Your target and the knobs that drive the estimate.

Smoothing (α) 0.10

Smoother ≈10-day window Reactive

Regression window

A longer window filters out short-term water swings for a steadier TDEE, but lags real changes; a shorter one reacts faster but is noisier.

Starting estimate (optional)

While you have too little data for a real estimate, TrendCut can show a generic day-1 estimate from a standard population formula (Mifflin–St Jeor). It is clearly marked as not from your data, carries a wide range, and disappears the moment your real estimate is ready. Filling all four fields turns it on; leave them blank to skip it.

Age

years

Biological sex

Height

Activity level

Your activity level is the roughest part of this estimate — it's a broad guess and the biggest source of error, which is why the range is wide.

Backup

Export your data

Downloads all logged entries (date, weight, calories). Settings are not included. Keep a copy somewhere safe — this is your backup.

Import from CSV

A flat CSV with a date and a weight column (calories optional). Common header names and date formats from other apps are recognised; lb values convert to kg. MyFitnessPal's multi-file zip is not supported.

Danger zone

Delete all data

Permanently removes every logged entry (weigh-ins and calories). Your account, settings, target, and demographics are kept, and you stay signed in. This cannot be undone — export a backup first if you want a copy.
