Become ADDICTED to exercise.

ExcerLock locks the apps you choose. They only open after you complete an exercise condition.

Sound familiar?

You said one more video. You said I’ll start Monday.

Let’s use your addiction to fuel exercise instead.

New rule: you can only scroll while walking.

How it works

Locked until you move.

Three steps. Then it runs itself.

1
Pick the apps to lock.

TikTok, Instagram, YouTube, games. Whatever eats your day. ExcerLock uses Apple's own Screen Time picker, so it never even sees your list.

They stay locked until you move.
2
Walk, and they open.

Prop up your phone and start walking. ExcerLock checks that you're really moving, then your apps unlock while you walk.

Stop walking, and the lock comes back.
3
Or arrive at the gym.

Save your gym once. Check in when you get there and your apps open. Skip the gym, and they stay shut.

A daily step goal or time at the gym counts too.

Why people stick with it

Hit your body goals.

When scrolling costs movement, you start moving a lot more.

Walk to scroll.

Your feed only works while you're walking. Suddenly a 20-minute walk sounds great.

Arrive at the gym to use your phone.

Make your gym the place your apps open. Showing up stops being a debate.

0steps today

More steps. Every day.

Set a daily step goal. Hit it, and your apps open. Miss it, and they wait for you.

Consistent at the gym.

No more "I'll go tomorrow." The gym visit is the price of your phone, so you pay it.

Fat-loss lock‑in.

Losing fat is mostly showing up on the days you don't feel like it. ExcerLock makes the walk and the gym session non-negotiable, so the streak survives.

ExcerLock is a habit tool, not a medical or weight-loss program.

Fitness continuity.

Miss one day and the next is harder. ExcerLock keeps the chain going, day after day, without a pep talk.

Block

Block the apps that eat your day.

Pick single apps or whole categories. Social, video, games. The lock is Apple's own Screen Time shield, not a hack.

Video
Games
News
Dating
