Move to unlock the apps that keep you sitting.
You said "most of it"
9h 12m
About 66% of your waking hours.
Recess opens by reading the motion data your phone has been keeping anyway, and telling you how long you sat on an average day this week. It is almost always more than people expect.
That figure is worked out on the phone and stays there. It is the one thing the app shows you before it asks for anything.
Choose the apps that pull at you
Two or three is usually enough. Maps, messages and everything else stay open.
Set your hours and your rhythm
Every 45 minutes by default, only during the hours you pick. Evenings and weekends are yours unless you say otherwise.
Move for a minute, and they open
Ten squats, or sit-to-stands, or arm raises. Your camera counts them, then the apps come back.
Six exercises, and you pick the one you feel like. The camera counts the reps, and never records them.
A moment of science
Ten squats can do what a walk can't.
In one study, short movement breaks every 45 minutes controlled post-meal blood sugar better than a single 30-minute walk. Frequency beats duration.

The camera counts your reps on the device and nothing else. No photo or video is saved, and none of it is uploaded, because none of it leaves your phone.
Recess never learns which apps you chose either. On iPhone that choice is handled by Apple's Screen Time, which tells apps nothing about it.
There is no target to miss and no streak to break. A quiet week costs you nothing. And when you genuinely cannot move, one link lets you through without pretending otherwise.
