Open the weight loss hubWe're targeting summer 2026. Waitlist members get access in waves as we expand capacity, with earlier signups going first. We'll only email when there's news worth your inbox.
iOS, Android, and Web on day one. Apple Watch and Wear OS companions ship soon after.
Independent research on commercial food vision models finds calorie estimation error from a single photo lands roughly in the 10-30% range for typical Western plates, widening for mixed dishes and stews. That is comparable to portion-size variance in manual logging. CaloriesCam will show a confidence cue and an edit slider on every scan so you can correct the estimate when the meal includes hidden ingredients (oils, sauces, dressings) or unusual portion sizes.
Yes. The on-device model handles barcode scanning and most photo calorie estimates without a connection. Restaurant menu lookups and health-app sync require network.
You don't have to. Manual search and a saved-foods list are first-class. The camera is the default because it's faster, not the only path.
Photos are processed and immediately discarded. We keep the nutrition data, not the image. On-device-only processing will be available as a toggle for full privacy.
