Why it works

Friction where you need it. Reward where it counts.

Lock the apps that steal your day

Choose the feeds, games, and other apps that pull you in. Lock100 adds a workout checkpoint before you can continue.

The camera counts every rep

Prop up your phone and go. On-device vision tracks your form and tallies reps in real time — no footage ever leaves the device.

Climb the ladder to 100

Start where you are, even with a few reps. Your daily target grows gradually as you build toward 100 pushups in a day.

Watch the streak grow

Complete your full daily goal to extend your streak. Track daily progress, lifetime reps, weekly activity, and milestones along the way.

Open the app you
shouldn't. Earn it back.

Three taps from temptation to done. The flow is designed to be quick and clear.
01

You hit the wall

Open an app you chose to limit and Lock100 shows today's movement goal before access continues.

02

You do the reps

Set down your phone and complete your pushups. On-device pose tracking counts each completed rep in real time.

03

You're unlocked

Finish the goal to unlock your selected apps and complete another day on your path to 100.

The ladder system

Everyone starts somewhere. Everyone ends at 100.

Lock100 starts from your current ability and gives you a manageable daily target. As you improve, the plan gradually builds toward 100 pushups in a day.
