GainLock: Exercise App Blocker

About this app

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

Most productivity blockers rely entirely 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.

How It Works

1. Pick the apps to block — Select social media, games, or any distracting apps that eat your day.
2. Open a blocked app — GainLock intercepts it instantly.
3. Do your reps — Complete physical exercises in front of your camera to bank screen time. Scroll only once you've earned it.

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

Real Reps, Counted by Your Camera

GainLock counts your motion using advanced on-device pose detection. No honor system, no tap-to-skip.

Sloppy reps get rejected, and landing short on a jump squat banks nothing. Choose from 8 supported exercises:

* Squat
* Jump Squat
* Push-Up
* Burpee
* Jumping Jacks
* High Knees
* Lunges
* Cross Crunches

A Focus App and a Digital Detox

GainLock is part app blocker, part fitness tracker. Beat phone addiction, build self-control, stay focused, and get a quick workout in every time you reach for a distraction. It's a digital detox that pays you back in health, giving you a productivity boost you'll actually feel.

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, ensuring equal effort earns equal rewards.

Build the Fitness Habit

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

Daily Streak Tracker — Watch your progress grow each day you show up.
Stat Tracking — Monitor your completed reps and total screen time earned.
Live Time-Bank — See a live countdown widget right on your screen.
Evening Reminders — Get an alert before your streak breaks.

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

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

**Does any of my data leave my phone?**
No. GainLock operates fully offline. Your pose detection data, reps, stats, and blocklist all stay entirely on your device.

**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. You can pick which apps to block and modify your blocklist anytime in the settings.

**Will it drain my battery?**
No. The camera and processing only run while you are actively earning time—never in the background.
