Your watch snitches on the workout. We move today's fuel to match — and the weight trend keeps us honest.

One connection, at setup. Nothing to log twice — if a session reached your phone, it's already in.
The gap
Adaptive, but blind
The good adaptive trackers refuse wearable data on principle. Your target catches up to a training block three or four weeks late — they say so themselves.
Training-aware, but unanchored
The performance apps do read your sessions, but nothing checks the estimate against reality. Wrong in, wrong out, week after week.
Or just “you burned 800”
The mass-market ones hand your watch's number straight back as food. Anyone who has raced knows how badly that overestimates.
How it works
Your session nudges today. Your weight trend decides whether the nudge was right.
/01
The spine
Weight and intake over time give a measured expenditure, not a formula's guess about your body.
/02
The session
A logged ride or lift perturbs today's target — mostly carbs, because that's what actually moves.
/03
The correction
If your watch overstates the burn, the trend catches it and quietly shrinks the effect. No settings to tune.
iOS first, English and German at launch.
