Onyx Tenet: Calorie Tracker

Onyx is the calorie tracker that learns. Your real burn rate, recalibrated every day from your real intake and your real weight. While other apps lock you to a formula on day one, Onyx watches what your body actually does and adjusts. The longer you use it, the more accurate it gets. LOGGING THAT GETS OUT OF THE WAY Snap a photo of your plate. Scan a barcode. Type "two scrambled eggs and a banana." Onyx fills in the macros in seconds. Save the meals you eat every week and log them with one tap. Tracking stops being the thing you give up on. A COACH THAT READS YOUR DATA Onyx Chat answers from your actual logs, not generic advice. Ask "did I hit protein this week," "when was my biggest deficit day," "why did my weight plateau." Real numbers, in plain language, on demand. BUILT FOR PEOPLE WHO WANT RESULTS No streaks holding you hostage. No rings to close. No notifications nagging you back. Onyx is calm, monochrome, and built to disappear once the entry is logged. The numbers do the talking. PRIVATE BY DEFAULT Your data stays on your device. Cloud sync is optional. No ads. No data sales. No third-party tracking.
