GainLock: Push Ups to Unlock

About this app

GainLock is the app blocker that actually works—an app locker that makes you earn screen time instead of scrolling it away.

Most app blockers stop doomscrolling for about a day, because they rely on willpower. You hit a timer, tap "ignore," and you're right back on TikTok. GainLock is different: the only way past the lock screen is to move your body.

Free with push-ups. GainLock Pro unlocks every exercise, with 7 days free to try it.

How It Works

1. Block apps that eat your day — social media, games, short-form video.
2. Open a blocked app — GainLock intercepts it instantly.
3. Do your reps — Exercise in front of your camera to bank screen time. Scroll once you've earned it.

Every minute of screen time is a minute you worked for.

Real Reps, Counted by Your Camera

Do push ups to unlock Instagram. Do squats to unlock TikTok. GainLock counts every rep with on-device pose detection — no honor system, no tap-to-skip.

Sloppy reps get rejected: land short on a squat jump and it banks nothing. Push-ups are free; Pro unlocks all 8 exercises:

• Squat
• Squat Jumps
• Push-Ups (pushups)
• Burpee
• Jumping Jacks
• High Knees
• Lunges
• Cross Crunches

Walk to Earn

Too sore to train? Connect Health Connect and your daily steps bank screen time. The walk to the shops pays for the scroll home.

A Focus App and a Digital Detox

GainLock is part app blocker, part fitness tracker. Block apps while studying or working, beat phone addiction, build self-control, and get a workout in every time you reach for a distraction. It's a digital detox that pays you back in health.

Set Your Own Difficulty

Choose how hard you want to work—from an easy warm-up to a brutal hard mode where every minute costs real sweat. Tougher exercises pay more screen time per rep, so equal effort earns equal rewards.

Want a hard screen time limit? Set a daily maximum — earn it, spend it, locked till midnight.

Build the Fitness Habit

GainLock turns daily exercise into an automatic habit. Every workout builds your streak—miss a day, and it resets.

Stat Tracking — Monitor your reps and total screen time earned.
Achievements — Unlock badges as your reps and streak stack up.

Private by Design

Your camera feed never leaves your phone. Machine learning pose detection runs 100% on-device. No video is saved, no data is uploaded, and no account is required.

FAQ

What does it cost?
GainLock is free with push-ups: block as many apps as you like. GainLock Pro unlocks all 8 exercises, with 7 days free through Google Play — cancel before it ends and you're not charged. After that it's AU$14.99 per month or AU$47.99 per year, billed in your local currency. Prefer not to subscribe? There's a one-time AU$69.99 lifetime purchase.

Do I need to allow camera access?
Yes—that's how GainLock counts your reps. The feed is analyzed live on your phone and never recorded.

Does any of my data leave my phone?
No. Your pose detection data, reps, stats, and blocklist all stay entirely on your device. No video, no account, no analytics, no servers — the only thing that ever talks to the outside world is Google Play, for your subscription.

Can I cheat the rep counter?
No. The AI pose detection rejects incomplete or fake reps. The screen time you earn is time you actually moved for.

Can I unblock an app later?
You stay in control — pick which apps to block and change your blocklist anytime in settings.

Will it drain my battery?
No. The camera only runs while you're actively earning time—never in the background.

No ads. Ever. No willpower required.
