Abstract
Most people quit One Sec because it only stops you from opening an app, not from staying trapped inside it, because its effectiveness fades after weeks of use, and because it punishes quick message checks alongside endless scrolling.
One Sec vs Screen Time vs Brick vs Freedom: compared according to reddit
Gets in the way when you need it 1 = Didn't notice · 2 = Mildly annoying · 3 = Noticeable · 4 = Frustrating · 5 = Made me want to quit
Reduction strength 1 = No real change (~0-10%) · 2 = Slight decrease (~10-30%) · 3 = Moderate decrease (~30-60%) · 4 = Large decrease (~60-90%) · 5 = Total reduction (100%)
The Unscroll hypothesis (dotted circle): Unscroll is new and doesn't have independent Reddit data yet. Read more on the transparency of this research and the weaknesses of this approach below.
How these scores are chosen
Both axes are 1-5 scores averaged from real Reddit users' answers to a fixed-choice question — see the answer-dictionary legend for exactly what each answer means. Hover any point for how many people are behind each score, and a verbatim quote from the median-scoring one of them.
15 of 16 solutions here have both axes directly measured from real Reddit users; the rest borrow a score for at least one axis — shown as hollow, dashed dots.
The quote shown for each axis is the median-scoring user of everyone found for that solution, not the most quotable one, so it represents the score rather than the extreme. Axes with a borrowed or manually seeded score have no quote, by design.
Gets in the way (X)
Gets in the way — how much the tool disrupted the user in the moment (a blend of how often and how intensely it did, judged as a single gut-feel answer rather than two separate scores, since either factor alone can dominate the felt experience)
Reduction strength (Y)
Reduction strength — impact on scrolling screen time
Show all 16 tools and their evidence
The rare person able and willing to give up the smartphone entirely.
"I’m addicted af. I just can't stop. YouTube, X, facebook, reddit, even Pinterest and more … I keep uninstalling those but then I'm weak and I go back … I’m tired of my phone being constantly glued to my hand."
"I work in the influencer marketing space ... I've literally uninstalled instagram (been > 6 months now) and hardly use any other social media platform. Seemed hard earlier, but it's been so great lately."
People wanting a reset (a weekend or week off) rather than a permanent system.
"I had a similar thing happen to me. I went cold turkey and my anxiety increased. I also started waking up with existential dread… I would recommend a sharp reduction (not gradual) but also not cold turkey."
"Cold turkey. Quit fb and insta… Had my spouse change my passwords so I couldn’t cheat easily… almost immediately I was feeling better mentally… Still cheating a little via Reddit though 🫣"
People ready to go cold turkey on specific apps and who can still access them via browser if truly needed.
"I have uninstalled instagram, and logged it on to the browser version. Reels barelly load, the overall surface is much slower and everything is so annoying that I just close the app and find something elso to do."
"social media is such a problem but then I also love it haha. … it also ruins me and I have adhd so i get easily sucked into the doomscrolling cycle. I delete social media of my phone quite frequently."
Heavy doomscrollers with decent baseline discipline who don't need blocked apps for messaging friends.
"Opal is too easy to bypass, but I still use it as a second block on top when I do ‘unbrick’ (I know it’s excessive but i truly have not self control). I think anything that I can unblock apps from the phone became too easy for me..."
"block apps like fantasy, reddit, barstool completely from 5-7p after work during play time, dinner, and bath Opal is a good one."
The Unscroll hypothesis — our target, not yet tested against independent Reddit data. That's why it's a dotted circle.
People who need their feeds for work/social life but want real-time awareness of how long they've been scrolling, without hard blocks they'll just bypass.
People who want a physical commitment device: tap a hardware tag to unblock, so bypass has real friction.
"Even when I work from home I find it is way better than other options because you have to make a choice to get up from your desk and go to wherever the brick is."
"I use it and love it! I have it set to auto-brick at like 6am so its a choice I have to make every day whether or not I want to unlock it or not... It’s been a big game changer for daytime distractions."
People willing to carry a classic feature phone and lose smartphone apps.
"I'm autistic and also have ADHD… going to a full dumb phone made things like checking my bank, accessing my calendar… so much harder."
"I’m also in Australia and have the Barbie HMD version of this same phone and I'm also loving feeling more present and in the moment when I'm out and about either by myself or with friends."
People who want to break the automatic open-and-scroll habit without losing access to the app entirely.
"I love it because sometimes all it takes is me seeing that I’ve opened Reddit 21 times in 24 hours and it’s just like… wtf man… Other times, just knowing that it’s not going to open right away ... feels like so much dumb work that I just don’t even bother. Highly recommend."
"Every time I try to open Instagram, I get redirected to the one sec app where I’m forced to wait 10 seconds. This is just long enough for me to think about what I'm doing… Since I started using the one sec app in December, I've saved a whopping 16 hours of time."
People on Android who want a built-in, free, zero-setup daily app-category limit (the Android equivalent of iOS Screen Time limits).
"Android has the digital wellbeing feature under settings and the grey scale is under bedtime mode. I also use the focus mode which blocks some of my apps - it's easy to circumvent but clocking ‘use the app for 5 minutes’ again and again makes me more aware that I'm just scrolling."
"If anyone else is trying to decrease their phone use, I'd recommend the Digital Wellbeing app… You can see your total phone use time, and set time limits for certain apps. Putting a 30 minute daily limit on Reddit helped cut my screen time significantly."
People who want a minimal-but-usable phone (maps, messaging) without infinite feeds.
"I had an Alcatel Smartflip for exactly 6 months… As time went on, it just got so frustrating. More crashing, freezing, shorter battery, texts not being received sometimes etc… it turned into a game of how I could still binge the internet, no matter how slowly things loaded."
"I’m an environmental scientist employed at an engineering company. My work provides a smartphone for field employees, so I use that for authentication and any apps that I need for work … When I’m not working, the phone goes in my desk drawer and I just use my LPII."
People who want a dumbphone feel (grayscale, text-only launcher) while keeping their smartphone.
"yes, a lot, i didn't use it anymore. olauncher is also 1/10 times frozen when open too. I didn't use those anymore but I keep blackscreen. Now I use plain oneUI that come with samsung."
"I thought about getting a dumb phone but didn't want to part with a decent mobile camera, so I got one of those dumb phone overlays which has honestly cut my screen time right down."
People who want a free, instant, no-app tweak that makes the phone slightly less rewarding.
"Helps me not go down the rabbit hole of scrolling through instagram stories!! My ADHD brain isn’t stimulated by the boring colorless stories."
"I don’t think grayscale has been the main reason I’m getting less screen time, but it definitely helps me. If anything, it just feels good to have less stimulation in my eyes and brain. At first I hated it, but now I don’t think I could go back."
Users who want a breathing/pause gate plus blocking on chosen apps.
"I just downloaded the app and I’m trying to do a squat challenge and it is not recording my squats."
"i find that apps that truly block you from accesing your socials are more effective than this motivational ones..."
Users who want friction added to opening specific scroll feeds, app only unlocks when you do exercise.
"guys, i have installed push scroll to reduce my screentime on my phone, but my screentime on the app wont go down, like if I have 30m, and i use my phone for 10, it still remains 30m on the app, whyy any solution?"
"Hey you can try out this app called PushScroll. It makes you do pushups if you want to doomscroll. So kills two birds with one stone. Get gains and reduce scroll time."
People who want a built-in, free, zero-setup app limit and have enough self-discipline not to tap 'Ignore Limit'.
"I wish apple would make it harder, my fingers just default to clicking the ignore this limit button instead of clicking off the app. It’s a reminder but you have to stop and think about your actions yourself…"
"I don’t think I’ve ever hit anything other than ‘ignore limit for today’. It maybe gives me a bit of a jolt and I then use the apps less for the rest of the day than I would otherwise have done, but over the peace I’d say they don’t work for me."
Cross-device users (phone + desktop) wanting scheduled, hard-to-bypass blocking for deep work.
"I have used Freedom for several years and like it. I have layered scheduled block lists across the work day and bedtime. I use the stricter mode that doesn't let you delete apps or edit blocklists when a session is running..."
"Freedom is very annoying from my experience, the VPN will get in the way of some apps even if they are not in the block list. I found I was constantly having to delete the app to use a train ticket app…"
Surprising findings about One Sec
iOS Screen Time limits, a free built-in tool, scores worse on both axes than the paid app One Sec.
Why this is surprising A reasonably informed reader would assume the free, platform-native option is less intrusive and at least as effective as a third-party app, not more intrusive and less effective.
Evidence iOS Screen Time limits scores 3.75 on gets_in_the_way (n=12) vs one sec's 2.86 (n=14); iOS Screen Time limits reduction_strength 2.3 (n=20) vs one sec's 2.73 (n=26).
One Sec's own research indicates the optional dismiss button is the most effective component, not the breathing pause that the app's marketing primarily highlights.
Why this is surprising The app's landing page and store descriptions center on the deep-breath intervention, yet their own preregistered experiment shows the dismiss button (a simple 'skip') contributes more to behavior change.
Evidence Extended research finding: 'A complementary preregistered online experiment found that the optional dismiss button was the most powerful component, with the time-delay friction and the deliberation message also contributing, meaning the effect is not driven by the bare 10-second static pause alone.' (onesec.app research page).
The real reasons people leave One Sec
Single-moment intervention gap
It only blocks the first open, not continuous scrolling. Users can open an app once then scroll indefinitely, bypassing the core interruption.
Diminishing returns through habituation
Effectiveness fades over weeks as users habituate to the breathing pause or find creative bypasses, returning to old usage patterns.
Too aggressive for messaging use cases
Re-interventions during quick message checks make social app use frustrating, pushing users to disable it for those apps entirely.
Is One Sec worth it, according to app store reviews?
Users report that One Sec effectively reduces screen time (e.g., from 6 hours to 2 hours or less) by introducing a breathing pause that helps break automatic app-opening habits. Many describe it as life-changing and more effective than alternatives like Opal.
The free version limits blocking to one app, and many essential features require a subscription. Users also encounter bugs, crashes, and unreliable behavior (e.g., not working on latest iOS), along with a complex setup process requiring Apple Shortcuts.
"Cut my screen time dramatically instantly"
"my Instagram is down to 1/3 of last week"
"screen time went from 6 hours a day to an average of 2 or less"
"Free version allows only one app to block"
"Will only let you put controls on one app if you don't pay"
"Having app switching locked behind the subscription was already enough"
"I realized I was navigating to Instagram without even thinking about it"
"it's really eye opening to see how many times I opened this app"
"This app effectively broke the muscle memory habit of opening up Instagram"
"Just giving me this few seconds to think about it helps save me so many hours"
"I love taking a deep breath, changes everything"
"makes you take a deep breath – most of the time this makes me put my phone down"
"it just does not work anymore"
"App keeps crashing, so no other apps work either"
"Sometimes it just doesn't open and skips the screen"
"Changed my life, no exaggeration"
"genuinely changed my life"
"This app brought a change to my life that was desperately needed"
"intentional app switching behind a paywall"
"almost every single feature is paid"
"then overnight they say that they will only lock you out of 1 app"
"Too complicated to set up, It takes 2 apps to set up"
"I have to manually set up a shortcut to get even basic functionality"
"the fact that I have to memorise the steps and manually setup the automations was just an immediate huge hurdle"
"it doesn't work on the latest iOS"
"Wake up block? Doesn't work. After 5 minute interval block? Also doesn't work"
"Safari says extension has failed"
"Used to use Opal but this is the superior app"
"I've used and paid for subscriptions, apps like opal etc. This app is by far the most effective"
"Screenzen is a better app. (negative, but the positive ones say it's better)"
What the research says about One Sec's mechanism
The research on screen-time interventions is modest but points to several mechanisms and outcomes. The evidence base is still developing, with key studies showing small average effects and important individual differences.
In the closest controlled comparison of self-nudge mechanisms, the 'one sec' app found that requiring an active choice pause and imposing a passive delay produced similar reductions in app opens, suggesting neither friction design clearly out performes the other.
Multiple randomized controlled trials consistently find that assigning participants to limit social media to ~10 minutes per platform per day or to deactivate for 1-4 weeks leads to small improvements in well-being (depression, loneliness, anxiety). The largest RCT with 3,225 students found no net effect on overall well-being but noted trade-offs.
The evidence increasingly shows that the effects of social media are highly individual: some users benefit from reduction while others (e.g., those relying on it for active social connection) lose well-being from abstinence. No universal dose-response threshold has been established, and blanket reduction may harm vulnerable groups.

Who does One Sec actually work for?
When One Sec works best
One Sec fits heavy doomscrollers who open apps out of habit and have no messaging needs. It reduces screen time from 6+ hours to 2 hours or less by adding a breathing pause at each app launch. But only if you don't need to check messages quickly and can resist bypassing it over weeks.
- Heavy doomscrollers (6+ hours daily)
- Habitual app openers, not message checkers
- Willing to accept a single intervention per launch
- Baseline discipline to not bypass over time
- No need for quick app access during the day
Why does One Sec fail long term?
Friction-based pause interrupts habitual app opening, relying on user intent over enforcement
One Sec introduces a brief breathing pause before a target app opens, breaking the automatic muscle memory of habitual use (s87). This friction creates a deliberate decision point, redirecting reflexive scrolling to conscious choice. The trade-off is that the intervention depends on the user's follow-through: it blocks only the initial open, not ongoing use, and its effectiveness requires the user to engage with the pause each time.
Best alternatives to One Sec that work differently
Screen time blockers
Requires upfront setup and discipline; easily bypassed by disabling the blocker or deleting the app; can block legitimate use.
By blocking the app entirely during set periods, these tools prevent any access to the scrolling feed, not just at the first open. This eliminates the opportunity for continuous scrolling because the app cannot be opened.
- Single-moment intervention gap
- Susceptible to bypass via app deletion or ignoring limits; can be too aggressive for messaging apps if not configured properly; long-term habituation to the intervention schedule.
Freedom
Users who want scheduled, cross-device blocking with a locked mode that is harder to bypass.
Supported by a preregistered RCT (n=467, dz=0.45)
Brick
People who want a physical commitment device requiring a tap to unblock, adding real-world friction.
No direct study; mechanism reduces ease of bypass.
Live screen time
Less forceful than blockers; requires trust in the mechanism; may not be enough for heavy habitual users.
Intervenes continuously during scrolling, not just at app open, so the gap is eliminated. Uses random button placement and cheap exit to reduce habituation. Only blocks the feed, not the app itself, allowing messaging without friction.
- Single-moment intervention gap
- Diminishing returns through habituation
- Too aggressive for messaging use cases
- Still requires self-discipline to respect the intervention; weaker immediate reduction than hard blockers; effectiveness depends on user buy-in.
Unscroll
People who need their feeds for work/social life but want real-time scrolling awareness without hard blocks.
Based on internal data showing 52% average reduction.
Small hacks
Minor visual inconvenience; no direct blocking; may be insufficient for heavy users.
By globally reducing the visual reward of the phone, grayscale dampens the allure of scrolling throughout the session, not just at open. It doesn't create a recurring intervention that users can learn to ignore.
- Single-moment intervention gap
- Diminishing returns through habituation
- Does not reduce how often users pick up the phone; relies on sustained effect which may fade; no protection against checking with color apps.
Grayscale mode
People who want a free, instant, no-app tweak that makes the phone slightly less rewarding.
Replicated finding: d≈0.39–0.46 reduction in session duration.
Abstinence
Drastic reduction in functionality; requires strong resolve and lifestyle compromise.
By completely removing the app or device, there is no opportunity for the single-moment gap to occur, no intervention to habituate to, and no conflict between blocking and messaging.
- Single-moment intervention gap
- Diminishing returns through habituation
- Too aggressive for messaging use cases
- High friction for maintaining long-term; social and logistical challenges; browser access may still allow scrolling.
Deleting the apps
People ready to go cold turkey but who can still use browser if absolutely necessary.
Analogous to Facebook deactivation study on reduced use.
Temporary digital detox
People wanting a reset (a weekend or week off) rather than a permanent change.
Supported by 14-day abstinence RCT results.
Dumbphone
Significant lifestyle change and cost; requires carrying two devices if apps are needed.
Replaces the smartphone with a device that physically lacks infinite-scroll feeds, eliminating the source of the problem entirely. No app to open, no gap, no habituation, and messaging remains functional.
- Single-moment intervention gap
- Diminishing returns through habituation
- Too aggressive for messaging use cases
- Loss of essential apps (maps, banking, work tools); requires separate devices; may not be practical for everyone.
Dumb touchscreen phone
People who want a minimal phone with maps and messaging but no feed apps.
Analogous to full-blocking RCT evidence.
Nokia (feature phone)
People willing to carry a classic feature phone and lose all smartphone apps.
Analogous to strongest evidence on full channel closure.
