Train with numbers you can trust. Log food in seconds. See what is changing. QuietGains keeps your training, nutrition and progress in one place. Log every set, follow weight and rep targets worked out from your own history, track calories and macros, and watch your numbers change over time. TRAIN WITH A CLEAR NEXT TARGET Pick a split or build your own, then log sets without leaving the session. Your last performance, the next target, warm-ups and rest sit right on the set you are logging. • Weight and rep targets calculated from your own logged sessions • Last session's numbers on every set • Personal records, spotted as they happen • Warm-up sets and rest timers • Strength, cardio and timed exercises • Supersets and custom exercises • Exercise videos, form cues and muscle maps • Full workout history and summaries BUILT AROUND YOUR GYM Save the places you train and the equipment each one has. Scan a machine's weight stack and targets snap to the weights it actually has. If a gym is missing something your plan needs, QuietGains swaps in an exercise you can do there, and you can restore the original with one tap. LOG FOOD SIX WAYS Search, scan a barcode, snap a nutrition label, take a photo, say it, or enter it yourself. Calories, protein, carbohydrates, fat, water and available micronutrients all sit in one daily view, with targets calculated from your details. SEE YOUR PROGRESS Follow strength, body weight, training consistency and muscle balance over time. Add progress photos and body-composition results, entered by hand or read from a supported scan sheet. ASK ABOUT YOUR LOG Ask how your training has gone and QuietGains answers from what you have logged: what the numbers show, how sessions compare, and what it does not know. It reads your log. It does not coach, and it never tells you what to change. ON YOUR WRIST The Apple Watch app runs alongside your iPhone during a workout. See your exercise, adjust weight and reps, log sets, follow rest and track heart rate without reaching for your phone. WORKS WHERE YOU TRAIN Basements and concrete walls do not stop a workout. Logging keeps working offline and syncs when you are back online. The free plan never expires. Premium adds more through a monthly or yearly auto-renewing subscription, which you can manage or cancel in your Apple Account settings. QuietGains provides general fitness and wellness information. It is not a medical device and does not diagnose or treat any condition. For individual advice, work with a qualified coach or health professional.
