Retain: Macros & Muscle

Build a routine that works for you. Retain brings workouts, food, water and progress together in one simple daily view. TRAIN YOUR WAY Find familiar exercises in a catalog powered by RepDB. Search alternate names, use muscle, equipment and difficulty filters, or describe a machine to find a match. Choose a ready-made routine or build your own. Organize exercises with easy up and down controls. Log sets, reps and weights, use a rest timer and pick up where you left off. Celebrate progress in weight, reps and sets with optional achievement settings. MAKE EVERY SIP COUNT Add water in ounces and see your daily, weekly and monthly history. Keep water controls within reach during your workout. Small habits, one day at a time. FOOD THAT FITS YOUR DAY Track calories and macros. Search foods with FatSecret, scan supported barcodes or add your own food and supplement labels. Use flexible portions, build recipes and account for the ingredients you actually use. Review amounts and available nutrients before logging. Food values are estimates; missing values stay unavailable. EASE INTO MOVEMENT Explore warm-up and cool-down moves with short, clear instructions. Optional reminders help you pause before an exercise, and you can turn them off whenever you like. SEE YOUR PROGRESS Keep your workout history, weight, measurements and progress photos together. Live Health can show daily steps, active energy and average heart rate from Apple Health, with your permission. Imported readings stay on your device and do not change your food diary or calorie target. Separately choose which eligible Retain records to share with Apple Health. MAKE IT YOURS Choose water, steps, nutrition and workout widgets, follow an active workout with Live Activities, and open Food, Water or Train with Siri shortcuts. Use pounds or kilograms and enable optional Face ID or Touch ID. Widget updates follow the schedule iOS allows; step widgets require separate permission. Retain is for adults 18 and older. It provides personal logging, estimates and general wellness information, not medical diagnosis, treatment or medication dosing advice. Follow your clinician's guidance for medical decisions. Food data: Powered by fatsecret Platform API. Exercise data: RepDB (repdb.co). Food and barcode availability varies. Apple Health is optional; readings depend on your permissions and available records. Widget sizes, Live Activities, Siri and biometrics depend on device and system support.
