Twenty seconds on the scale.
Slide the ruler to your weight and you're done. Kept turns it into a 7-day average, so one salty dinner never ruins your day.
Works with
Apple Health
and any smart scale that syncs to it
What usually happens
Most weight comes back slowly. That's the part you can catch.
Regain after stopping doesn't arrive overnight. It creeps up a kilo at a time, which is exactly when a small change still works.
⅔of lost weight regained within a year of stopping semaglutide, on average, in the STEP 1 trial
75%of people keeping weight off long term weigh themselves at least once a week, in the National Weight Control Registry
+1.5 kgwhere Kept taps you on the shoulder, measured from your own lowest weekly average
Sources: Wilding et al., 2022, STEP 1 extension; Wing and Phelan, 2005, American Journal of Clinical Nutrition. A 2026 BMJ review of 37 studies found similar regain. The dashed part is a projection. Averages describe groups, not what will happen to you.
How it works
Small, boring, every day. That's the whole trick.
See the drift at one kilo, not ten.
Your band runs from your lowest weekly average to +1.5 kg. Drift above it and Pip nudges you while the fix is still small.
A plan for when the food noise gets loud.
Write it while you're calm. When it gets loud, one tap opens it and Pip breathes with you.
this will pass
Name the noise.
One tap a day. Over a few weeks you see what turns it up and what quiets it.
Days in a row that feel good.
Each check-in lights up a dot. Miss one and nothing breaks.
Every week
Pip reads your week with you.
One thing to keep and one thing to try, built from your own check-ins. Finishing feels like a small win.

Questions
Good questions.
Is this medical advice?
No. Kept is a wellness and habits app. It never asks about or advises on doses, and it doesn't tell you whether to stop or restart a medication. Those decisions belong to you and your prescriber.
Do I need to have stopped already?
No. It works if you've stopped, are cutting down with your prescriber, are taking a break, or are still on it and planning ahead. Your band adjusts when your stage changes.
What happens to my weight and hunger data?
It stays on your phone. We never sell health data or send it to advertisers. You can export or delete everything from the You tab at any time.
What do I need?
Just an iPhone. Type your weight in each morning, or let your smart scale fill it in through Apple Health. Android is on the way.
What if Plus isn't for me?
Cancel during the free week in your App Store settings and you won't be charged. The daily check-in, your band and your loud-moment plan stay free.
