Gym Data records your training and your food by the numbers. Enter the weight and reps, and it shows what you lifted last time, counts your weekly sets for every muscle and adds up your calories and macros. In English or Arabic, and everything you log stays on your phone. ■ Log every set at the gym • Weight, reps and effort for each set, or seconds for holds like the plank, with a built-in stopwatch. • "Last time" sits next to every set. One tap fills it in. • Supersets: two exercises back to back on one screen, with rest after the round. • Rest timer, warm-up sets, notes and an A, B or C rating for how each set went. • Kilograms or pounds, and exercise names the way the gym says them. ■ Ready programs, or your own • Space: weekly programs from 2 to 6 days, staged plans and diet plans. Pick one, import it in English or Arabic, and your next workout is waiting on Today. • Or build your own plan with days, exercises, rest days and other activities like walking or yoga. • Or plan it with the AI assistant you already use, using the ready instructions in the app, then import the file and review it before it is added. ■ Food and calories • Log what you eat and track calories, protein, carbs, fat and fiber. • Add a meal from a photo or a description: copy the instructions, send them with your photo to the AI assistant you already use, then bring the reply back and review each food before adding it. • The calorie calculator works out cut, maintain and bulk targets from your measurements and activity, shows how it got there, and lets you edit them. • Ready diet plans with clear servings and calories for every meal. • Supplements and courses with doses, schedules and reminders, plus a Face ID lock for details you want to keep private. ■ See your progress • Personal records and a progress chart for every exercise. • Weekly training volume for every muscle. • Body measurements, weight and body fat, with optional read-only access to Apple Health. • A report for any period as a PDF, Excel or Word file to share with your coach. ■ Your data stays on your phone Everything you log, from workouts to food to measurements, is saved on your device. Gym Data does not upload it to us or to any cloud service. You sign in with Apple, Google or email, and nothing you log is uploaded to your account. To move to a new phone, use the backup file in the app. Gym Data records and calculates; it does not give medical advice.
