Find a strength coach, talk through your goals in chat and train to their program. You log sets, cardio and planks on iPhone or Apple Watch, the app counts volume and records, and your coach reviews every session. Next to your workouts sit a nutrition guide and your body measurements. COACH DIRECTORY • Coach profiles: focus areas, experience, city, format (online or in person), languages and working terms. • A profile goes live after a moderator reviews it. Coaches state their own experience and qualifications. • You write first. If it's a fit, send a request right from the conversation. The coach sees your workouts only after accepting it. • Already have a coach? Connect with an invitation code. CHAT WITH YOUR COACH • Message your coach inside the app, no phone numbers exchanged. • Share a workout or its result in chat, your coach opens it with one tap. • Read receipts and notifications for new messages. • Block or report anyone you talk to. WORKOUTS • Today's workout with target weights and your coach's notes. • Log a set in two taps. You enter weight and reps, the app counts volume. • The rest timer follows your coach's targets: add time or skip it. • The summary puts target and actual side by side. • You can also build a workout yourself, no coach needed. CARDIO AND TIMED EXERCISES • Treadmill, indoor cycling, elliptical, stair climber and planks with a time goal. • An interval timer you can pause. Forgot to start it? Enter the time by hand. • The summary shows goal and actual for every interval. HEART RATE • The app reads your average and max heart rate for the session from the Health app. You and your coach both see it. BODY MEASUREMENTS • Weight, height and measurements: chest, waist, glutes, left and right biceps and quads. Every field is optional. • A goal for each measurement and charts of your changes. • A monthly reminder to update your measurements. • Only you and your current coach see them. Your coach sees your age, not your date of birth. NUTRITION • A guide in its own tab: macros for regular and training days, a meal plan, cheat meal rules and other notes from your coach. • On a training day the app highlights your training macros. You can switch the day type yourself. • You get a notification when the guide changes, and the history shows what changed. • No coach? Write the guide yourself, the app works out calories from protein, fat and carbs. • Optional daily check-ins and a weekly report for your coach. This is guidance from your coach, not a calorie counter: there is no food diary. APPLE WATCH • Start the session on iPhone, the watch joins it on its own. • On the watch: current set, weight, reps, rest timer and cardio timer. • The watch records heart rate and active energy through HealthKit. The phone can stay in your bag. • Without a watch the app works the same way, from the phone. RECORDS AND PROGRESS Four kinds of records update after every session: heaviest weight, estimated 1RM (Epley formula), best weight for 1, 3, 5, 8 and 10 reps, and session tonnage. Charts show weekly volume, how closely you hit your targets, and the 1RM curve per exercise. You see the lifts that grow and the one stuck at the same weight for four weeks. FOR COACHES • A profile in the directory: new athletes find you. First messages land in Inquiries, and you accept a request right in the conversation. • Workout builder: exercises, sets, reps, weights, timed cardio and planks, rest, a note to the athlete. • A nutrition guide in the athlete's card. • The review queue and set-by-set review: target and actual in one table, heart rate and calories. • Athlete progress and body measurements on charts. PRIVACY Sign in with Apple or Telegram, no password to set up. A conversation doesn't give access to your training, nutrition or measurements: only the coach who accepted your request sees them. Health data is never used for advertising. Free, no in-app purchases.
