First, the honest bit about Opal
Opal does exist on Android. But the app that built the brand, the one the press covered and the testimonials rave about, is the iOS version. The Android release is newer and Opal's own help says some iOS features are not yet available on Android. If you searched for an alternative, you may have noticed the gap. This page is a disclosure too: Broc is our app, and it's in the list. We've kept the comparison factual so it's useful even if you pick something else.
The six worth considering
| App | Mechanic | Bypass difficulty | Price |
|---|---|---|---|
| ScreenZen | Pauses and reflection prompts before apps open; usage goals | Low. Prompts can be clicked through | Free |
| one sec | A breathing pause before every open | Low. The pause ends and the feed is there | Freemium |
| Stay Focused | Timers, schedules, a strict mode | Medium. Strict mode helps, still timer logic | Freemium |
| Forest | Grow a virtual tree by not touching the phone | Low. The tree is imaginary and you know it | Paid |
| Unrot habit app | Habits earn coins via timers or photo checks; coins unlock apps | High. Its official site currently links only to iPhone | Subscription |
| Broc | Apps locked until daily habits are done, verified by AI photo or timer | High. No snooze; the only way through is doing the habit | Subscription, 7-day free trial |
Which one fits you
You want gentle friction and zero cost: ScreenZen
The best free option here. Pauses, mindful prompts, per-app schedules. If your problem is mild autopilot opening, gentle friction may be all you need. If you've ever clicked through a prompt without reading it, you already know the limit of prompts.
You saw Unrot on TikTok, but you're on Android
Unrot's habit app uses earned screen time on iPhone: habits earn coins through timers or photo snaps, coins unlock your apps, and a little buddy grows when you follow through. Its official site currently links only to the App Store. A separate product that used the Unrot name links to an Android app now called Untap, with a different developer and mechanic. On Android, Broc offers the habit-gated approach: habits verified by photo or timer, apps locked until they're done.
You want an Android unlock tied to habits: Broc
Broc treats screen time as something you earn with your real habits. Block Instagram, TikTok, YouTube; set the day's habits; each one unlocks minutes. The wall has no snooze button, and AI photo verification checks the open book or the gym before a habit counts, so ticking the box from bed doesn't work. It's a habit app blocker: strictness tied to your goals, not to a clock.
What about Opal itself?
If you're deep in the Apple ecosystem, Opal on iPhone remains a polished choice with focus sessions and app-difficulty levels. On Android, judge the Android app on its own merits, not the iOS reviews: check the recent Play Store ratings before subscribing.
Common questions
Why trust a comparison written by one of the apps?
Fair question. The mechanics and prices above are stated plainly so you can verify each one on the Play Store in two minutes. Broc wins on exactly one axis, strictness tied to real habits, and we've said where the others win.
What does Broc cost?
Broc is a subscription with a 7-day free trial. One plan, everything in: unlimited habits, custom unlock durations, AI photo verification and full history. No ads.
Can any of these survive being uninstalled?
Broc does not prevent uninstall. Some Android device-management modes and strict blockers can restrict uninstalling or settings changes, but those protections vary. Broc instead makes quitting visible through your streak.
