The dashed forecast is what the app generates — a straight-line trend through your real morning weigh-ins, with a confidence band that updates as you log more days. The estimate moves when your pace changes.

We log your meals from just your voice

No more tedious manual tracking. Just tap the microphone and say what you ate. We extract food items, estimate calories, and adjust your goal date automatically.
