Food & nutrition

Log meals with AI — describe what you ate in plain English and Claude parses the calories, protein, and fiber automatically.

Maintenance Mode — the feature no other GLP-1 tracker has

You worked too hard
to give it all back.

80% of people regain most of their weight within a year of stopping GLP-1 medications. Maintenance Mode gives you the data to be in the 20%.

Your personal weight band

Set a target range — not just a number. A live tracker shows exactly where you are relative to your goal, with trend analysis so you catch drift before it becomes regain.

Appetite Signal — the early warning system

Track hunger 1–10 daily. As you taper, we detect rising appetite over 14 days before it turns into weight creep. The signal that predicts regain before the scale moves.

Calorie trend, month over month

"↑ +148 kcal/day vs. last month" is the number that tells you whether your habits are actually holding as appetite suppression fades.

Taper progress tracker

Visualize your dose ladder from peak to zero. The stability counter tells you exactly how many weeks you've been in range — so you know when you meet the criteria to step down.

Rebound Risk Indicator

A Low / Medium / High signal combining weight trend, appetite, calorie drift, and habit score. Act at 3 lbs, not 15.

"The medication gave you a window. What you build in that window is what lasts."
