If One Sec's breathing pause has stopped working for you, Repscroll is the stricter alternative. One Sec adds a short pause before an app opens so you can decide whether you really want it. Repscroll keeps your chosen apps locked until you earn screen time with exercise, and your iPhone camera counts the reps and checks your form.
One Sec is a good app, and for plenty of people a pause is all they need. This guide covers why people outgrow it, how Repscroll is different, and who should stay with One Sec.
What One Sec Does Well
One Sec puts a short intervention in front of the apps you pick. By default it's a breathing animation. After it finishes, you choose whether to continue or close the app. A re-intervention can end a session after a set time, so you have to go through the pause again to keep scrolling.
According to its help center and App Store listing:
- Free plan: one sec is free to use with one app
- Pro: unlimited apps, other intervention types, time tracking, website blocking and strict block sessions
- Pricing: Pro is listed at $6.99 per month, $19.99 per year, or $99.99 lifetime, with family plans also available (check the App Store for current prices)
- Platforms: iOS, Android and desktop browsers (some Pro features are iOS-only)
The idea is simple: a lot of app opens are automatic. A few seconds of friction gives your conscious mind a chance to step in.
Why People Look for a One Sec Alternative
1. The pause becomes a habit too
The pause works because it interrupts autopilot. But after a few weeks, some people go on autopilot through the pause itself: open, breathe, continue, scroll. It stops being a decision.
2. You can still say yes
One Sec is designed to make you choose, not to stop you. If you consciously want to scroll, a breathing exercise won't get in your way. That's by design, and it's also the main reason people go looking for something firmer.
3. Nothing good comes out of it
Ten seconds of breathing is better than nothing, but you don't come away from the pause any healthier. People who also want to exercise more often want the friction to do double duty.
4. One app on the free plan
The free plan covers one app. If TikTok, Instagram, YouTube and Reddit are all problems, you'll need Pro anyway, and at that point some people compare their options.
How Repscroll Is Different
We wrote a full side-by-side in One Sec vs Repscroll. Here's the short version for people who are ready to switch.
The friction is physical
Opening a locked app means doing reps first: pushups, squats, situps, planks, pull-ups or jumping jacks. A breath is easy to take. Ten real pushups are not, which is the point.
Reps are checked
Repscroll counts reps with on-device machine learning and checks form, so half-reps don't count. You can read about how the AI counts reps and why form correction matters.
You can't just tap through
With Hard Lock and PIN lock on, switching Repscroll off in a weak moment is much harder. There's still an emergency option for situations that really can't wait. See the Hard Lock and PIN lock guide.
Movement during the day counts
Steps, walks, runs, cycling and workouts from Apple Health can earn screen time too, so an active day pays off. More in how Repscroll uses Apple Health.
Friends keep you honest
1v1 challenges, including Double or Nothing, let you compete with a friend over screen time.

Who Should Stay With One Sec
One Sec is the better choice if you:
- Mostly open apps without thinking. If the habit is automatic and a pause reliably snaps you out of it, you don't need anything heavier.
- Only struggle with one app. The free plan may be all you need.
- Use Android or need desktop coverage. Repscroll is iPhone only.
- Can't or don't want to exercise to unlock. A breathing pause works for everyone.
- Want a lifetime purchase. One Sec offers one. Repscroll is a subscription.
Who Should Switch to Repscroll
Repscroll is the better choice if you:
- Breathe through the pause and open the app anyway
- Scroll on purpose, not by accident, and need a real cost
- Want to build an exercise habit at the same time
- Want strict controls that are hard to undo on impulse
- Like competing with friends
Other One Sec Alternatives
- ScreenZen works on a similar pause-first idea, with delays that can grow longer with each open and stricter blocking options. It has no subscription and is supported by tips. See our ScreenZen alternative guide.
- Opal is the step up if you want scheduled, hard blocks across phone and Mac. See our Opal alternative guide.
Switching Tips
- Keep the same app list you had in One Sec. Those are your real problem apps.
- Start with a small rep goal so the first week feels doable.
- Mix exercises. Squats and jumping jacks are easier to do anywhere than pull-ups.
- Connect Apple Health so your walks count.
- Turn on Hard Lock once you trust your setup.
FAQ
Is Repscroll free like One Sec's free plan?
No. Repscroll is a paid subscription with no free tier and no free trial. If you want a no-cost option, One Sec's free plan (one app) or ScreenZen are worth trying first.
Is Repscroll harder to bypass than One Sec?
Yes. One Sec lets you continue after the pause by design. Repscroll keeps apps locked until you've earned minutes, and Hard Lock and PIN lock make switching it off harder.
Can I use One Sec and Repscroll together?
You can, but it usually isn't necessary. Stacking a pause on top of an exercise unlock just adds steps. Most people pick the one that fits their problem.
Does Repscroll work if I can't do pushups?
Yes. You can use squats, situps, planks, pull-ups or jumping jacks, and Apple Health activity like walks and runs can earn time too.
The Bottom Line
One Sec is a smart, gentle tool for automatic phone checking, and its free plan is a fair place to start. If you've gotten used to breathing straight through the pause, Repscroll replaces it with something you can't skip: real reps before you scroll.
Swap the pause for a set. Get Repscroll and earn your screen time.
