01 — CALIBRATION
It learns from your data.
Every week Asidu compares what you logged with how your weight moved and adjusts its estimate of your expenditure (Pro). Formulas are only the starting point.
COMING SOON TO IPHONE · FOR ENDURANCE AND STRENGTH ATHLETES
Eat for the training you actually do.
Asidu estimates your energy needs and refines the estimate with your own weight trend — and helps you time meals around the training in your calendar. Targets are shown as ranges, not single numbers.

HOW IT WORKS
Built on your data, layer by layer.
02 — RANGES
Targets as ranges.
Protein, carbs and fat are shown as target zones based on published sports-nutrition guidelines. You see where you stand, not a number that pretends to be exact.
03 — FUELING
Fuel around your sessions.
Add your training and Asidu suggests how to time your meals around it — what to focus on before and after, with two sessions merged into one timeline.
04 — HONESTY
Honest about uncertainty.
A data-quality barometer shows how reliable your estimate is right now, and what would make it more reliable.
05 — CYCLE
Cycle correction.
Water retention before a period can move the scale. Asidu looks back at your past cycles and reduces this effect on your weight trend. It doesn't predict your cycle. Free for everyone.

Log in seconds
Snap a photo, type a sentence or scan a barcode. Portions and favorites remember how you eat — and if the AI gets something wrong, tap Fix and say what's off.
Daily carryover
A short day or a surplus carries over to tomorrow's target — within small limits. A day you couldn't log fully can be skipped.
Recovery signals
HRV, resting heart rate and sleep against your own baseline — shown as data, never as a verdict.
Sensible limits
Your target isn't set below your basal rate without your confirmation, Asidu points out targets below common sports-nutrition recommendations, and protein rises in a deficit.

Taking a training break? Pause calibration and carryover so a few unusual weeks don't skew your estimates.
