Targets that adapt to you.
Every Monday, a check-in reads your week and proposes new targets. Accept them or keep yours. A check-in moves your calories by 250 a day at most.

How it works.
No guessing here. Fit Shapes compares what you eat with how your weight changes to find what you burn.

Your scale jumps with water, salt, and a late dinner. One high reading barely moves your trend weight. If your weight stays up, the trend follows.

What you burn
Your first target comes from a formula. As your logged days add up, Fit Shapes measures what you burn and relies on the formula less. After about three weeks, the number is mostly your own.
Questions?
How Adaptive Targets workDoes Adaptive Targets cost extra?
No. Adaptive Targets and the weekly check-in are included in every plan. If you would rather set your own targets, switch your Program to Manual in Account, under Goal, then Your plan.
Why did my target go down?
Your target follows what you burn, measured from your log and your weight trend. If the starting formula guessed high, the first check-ins trim it. As you lose weight, a smaller body burns a little less, so small trims later are normal too. It can go up as well, when you burn more than the formula thought. A check-in changes your target by 250 calories a day at most, and you choose whether to accept it.
How low can my target go?
Never below 1,200 calories a day, or below 60% of what you burn, whichever is higher.
How long until it’s accurate?
In your first week, your target comes from your profile. After 7 days of logging, Fit Shapes starts to measure what you burn, and after about three weeks the number is mostly your own. Import your history from another app and it starts from real data instead.
Do I need to log my workouts?
No. Your workouts are already in what Fit Shapes measures, because it works from what you ate and how your weight changed. Your target does not go up on the days you train, so you don’t eat your workouts back.
What about water weight or my cycle?
Fit Shapes follows your trend weight, not each weigh-in, and measures over about six weeks. A few days of water barely move the estimate. If a check-in still looks off, tap Keep current plan.
Do I need to weigh in every day?
No, but more weigh-ins make the trend steadier. If you skip days, the trend draws a straight line between your readings. A smart scale that syncs to your phone logs your weight for you.
Does it work for maintaining or gaining weight?
Yes. Choose to lose, maintain, or gain, and the check-in sets your targets for the weekly rate you chose.
