How it works

Lock it. Earn it.
Then open it.

Set it up once. From then on, screen time is something you earn.

STEP 01

Choose the apps to lock.

Pick any app on your phone. Add or remove apps from the list whenever you want.

STEP 02

Open one and GainLock steps in.

Before the app loads, GainLock asks you to earn it. Prop your phone up, pick an exercise and start moving.

STEP 03

Spend the minutes you earned.

Every clean rep adds time to your bank. A live countdown on your lock screen shows what you have left.

Pose detection

Your camera
counts the reps.

Prop the phone up and go. Pose detection tracks your range and body position on every rep, so half a squat does not count as a full one.

Range and alignment checked every rep
Live count on screen while you work
Works offline, no server needed

The blocker

Block any app
on your phone.

GainLock stops the app before it opens, not ten minutes in. The usage breakdown shows which apps are taking the most of your time, so you know exactly what to lock.

FAQ

Frequently asked questions.

How does the rep counting work?

Your phone’s camera and an on-device pose model track your joints in real time. GainLock checks your range of motion and body position on each rep. If you don’t hit depth or your form breaks down, the rep doesn’t count. Nothing is recorded or sent anywhere.

Is GainLock free?

GainLock comes with a 7-day free trial. You get full access and no card is required. After that it’s a subscription through Google Play. There is no free tier and there are no ads.

Which apps can I lock?

Any app installed on your phone. Most people start with social media, then use the usage breakdown to find the ones they didn’t expect. You can add or remove apps at any time.

What if I physically can’t do the exercises?

Walk to earn adds screen time from your step count through Health Connect, with no camera involved. There are also eight exercises at different intensities, and you set how much time each session is worth.

Does it work on iPhone?

Android only for now. iOS is on the roadmap, with no firm date yet.

Can I just uninstall it when I want to scroll?

Yes. It’s your phone and GainLock won’t hold it hostage. The goal is to put one deliberate step between the impulse and the feed. For most people, that step is enough.

Where does my data go?

It stays on your phone. Pose detection, your app list and your rep history are all stored on the device. There’s no account to create and no workout video is ever saved.
