Adaptive TDEE for iPhone

Stop restarting from a calculator.

BurnCurve learns from your weigh-ins and optional intake, then turns the trend into today's target.

BurnCurve Today screen showing a measured calorie target, uncertainty curve, and one adjustment

The number is useful. The memory is the product.

A static calculator gives you a confident estimate, then forgets you. BurnCurve keeps the history and shows when the estimate starts earning your trust.

Day one

An honest guess

Start with a standard formula estimate and a wide range. It is useful today, but clearly labeled as a guess.

This week

The band begins to narrow

Weigh-ins and optional intake reveal how your trend differs from the formula. BurnCurve shows the disagreement instead of hiding it.

Next month

A burn with a memory

See adaptive TDEE, weight, intake, and target history together. Get one concrete adjustment when the trend misses your goal.

The band is the product. It starts honest and wide, then narrows as weigh-ins and intake arrive. A salty dinner or a two-week plateau does not reset it, the band just stays wide a little longer. Nothing about your burn is ever hidden behind false precision.

Uncertainty, shown

A range you can reason with.

BurnCurve never turns a noisy estimate into fake precision. The ember curve shows where your burn most likely sits, while today's target reflects your chosen pace.

Guess, Learning, and Measured stages stay explicit.
Cut, maintain, or bulk at a pace you choose.
One next move replaces a feed of generic advice.

Eating left of the curve loses. The further left, the faster.

The trend becomes the instrument.

History is not a streak or a judgment. It is the evidence behind your target, preserved on your iPhone.

BurnCurve History screen showing adaptive TDEE, uncertainty, Apple Health comparison points, and burn versus intake — Adaptive TDEE and Apple Health remain separate estimates. Health never overrides what BurnCurve learns from weight and intake.

BurnCurve Goal screen showing cut, maintain, and gain choices with five pace options — Explore the energy tradeoff behind a goal before changing it. Fast paces carry plain-language cautions.

Your health history stays on your iPhone.
