App blockers for Android compared: which ones let someone else hold the key?
“Best app blocker” lists usually rank features. The question that actually predicts whether you will still be using one in a month is different: who can turn it off? This comparison sorts Android blockers by that answer.
The four kinds of app blocker
| Approach | Who holds the key | Examples | Best for |
|---|---|---|---|
| Built-in limits | You, instantly | Digital Wellbeing app timers, Focus mode, Bedtime mode | Awareness and gentle nudges |
| Strict-mode blockers | You, after a timer | AppBlock, Stay Focused, Freedom’s locked mode and similar | Fixed sessions you plan in advance |
| Friction tools | You, after a pause | one sec-style “take a breath” apps, grayscale, launchers that hide icons | Breaking autopilot opens |
| Partner-approved blockers | Someone you chose | FriendLock | Habits you keep failing alone |
Product details change often; this describes how each category works as of writing rather than any app’s current feature list.
Built-in: Digital Wellbeing
Free, already on your phone, and genuinely good at showing where time goes. App timers pause an app when its daily allowance ends; Focus mode greys out a set of apps for a session. The catch is one button: ignoring a limit is a tap away, and Focus mode has a “take a break” option. Treat it as a dashboard, not a lock.
Strict-mode blockers
The mainstream paid category. You set a schedule or start a session, switch on strict mode, and the app refuses changes until the session ends; some also block their own uninstall. They are the right tool for planned deep-work blocks. Their limit is structural: between sessions the phone is fully yours, and starting the next session is again a decision made by the person who least wants to. Reboots into Safe Mode and force-stop also end most sessions.
Friction tools
Instead of blocking, these slow you down: a breathing pause before Instagram opens, a grayscale screen, a launcher with no icons. They work well against mindless opens and badly against deliberate ones. Cheap to try and worth combining with a real blocker.
Partner-approved blockers
FriendLock takes the key off the phone entirely. A blocked app opens a lock screen; to get in you ask a paired friend, partner or parent, who approves from their phone or reads you a six-digit code. Unlocks are short and expire. The blocker has no settings PIN to forget or find, because there is nothing on your side to unlock with.
Honest limits: it needs a second person, and on a normal phone the owner can still bypass it with force-stop, Safe Mode or a reset. It tells your partner when that happens, which is the whole design: tamper-evident, not tamper-proof.
How to choose
- Haven’t tried anything yet? Start with Digital Wellbeing for a week to learn your numbers.
- Need protected work blocks? A strict-mode blocker on a schedule.
- Open apps without deciding to? Add a friction tool.
- Keep undoing your own limits? Give the key to someone else. That is the only change that addresses the actual failure.
