Cheiron

Cheiron gathers the tracking a bodybuilder does across notebooks, spreadsheets and reminders into one place: what you eat, how you train, the supplements you take, and where your weight and cardio are heading. FOOD • Log a food in a tap; scan a barcode to add a packaged one. • Build a meal prep once and log it by the portion, macros worked out for you. • Separate macro targets for training days and rest days. TRAINING • A simple lifting notebook: your split, your exercises, and what you did last time beside what you are doing now. • Strength over time for each exercise, from your top set's estimated one-rep max. • Cardio counted against a heart-rate threshold, toward a weekly goal. • On Apple Watch: log every set and time your rest without taking out your phone. BODY • Phases (bulk, cut, maintenance, conditioning) with a goal and your pace toward it. • Your weight trend, and an estimate of your maintenance calories from your weight and what you eat. • Sleep, resting heart rate and blood pressure alongside, from Apple Health. SUPPLEMENTS • Your own list, marked taken each day, with reminders at the times you choose. FOR YOUR COACH • Make a one-page check-in of any recent period and send it from your phone. PRIVATE BY DESIGN No account, no ads, no subscription, no tracking. Your data stays on your iPhone and Apple Watch. You can export everything you have entered, any time, as one file. Cheiron is not a doctor, and its numbers are estimates: talk to a doctor before changing how you eat or train.
