FitBoost: Workout Log

Your log picks the next weight

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

FitBoost is a training log for strength and cardio that turns your history into a concrete answer: how much to lift next. ■ A coach inside every workout Finish a set, log how hard it was, and your next set's weight is set for you. When fatigue starts costing you reps, it tells you to stop, and rest times adjust to how hard that last set was. The more you train, the more it learns your own stopping point and how you rate effort. ■ Your routines go up on their own Start a routine and today's weights and reps come from your last sessions. Hit the top of your rep range and it goes up; miss it and it holds; miss twice and it eases off. Each kind of equipment uses its own step, and after a long break you come back gently. ■ Muscle recovery map and pain notes A body map shows how recovered each muscle is from recent training. On days you'd hit something still recovering, the home screen tells you first. Log pain and the lifts that use that muscle get lighter, with substitutes suggested. ■ Strength balance Compares your squat, bench press, deadlift, overhead press and barbell row against typical ratios. If one is lagging, it suggests an extra set or an accessory for your routine. ■ My gym and plate math Add your bar and the plates you own to see what goes on each side and in what order. Suggested weights snap to loads you can actually build, in kg or lb. ■ Your records are free and unlimited Workout records have no cap. No account needed, and your log stays on your device. iCloud keeps your iPhone and iPad in sync for free, and a backup file moves your log to another device. The free plan includes up to 3 routines and 5 custom exercises. ■ Train with your coach Pick a date range and send your trainer a workout report. Trainers keep each client's log separate from their own. ■ Apple Watch Finish a set on your wrist and pick the effort. The rest timer starts, and a tap on your wrist says when it's time to go. ■ It works out your next load Completed sets of 12 reps or fewer feed Epley, Brzycki and Lombardi estimates, and we take the median. Log RIR and the reps you had left sharpen it further. ■ 535 exercises, every one with a guide Every exercise carries setup, execution, breathing and precautions. Filter by muscle group and equipment to find what you need. ■ Five languages Korean, English, Japanese, Simplified Chinese and Traditional Chinese. FitBoost PRO adds routine auto progression, a personal 1–15 rep load curve, the in-workout coach, targets that learn from you, strength balance fixes, plateau detection, gym-ready loads and a weekly coaching report, with unlimited routines and custom exercises. PRO+ adds a block-periodized program, daily intensity tuned to your readiness, weekly sets per muscle and nutrition targets.

1.4.1 - Plan warm-ups ahead: set warm-up sets apart from working sets in routines, schedules and the pre-workout screen. Auto-fill adds steps for your working weight and bar (PRO+). - Edit exercises from your schedule: tap an exercise to change its weight and sets for that day or for the routine (PRO). - Generated program routines made before warm-ups existed now include warm-ups for the main lifts. - Open the intensity program and cardio calculators right from the menu, and go from a 1RM result straight to an intensity program. - Warm-up sets are now marked on the watch. - Weights and reps you change in a routine or schedule are used as-is in your next workout. Auto progression picks up again after that workout. - Fixed exercise names staying in the old language after changing the app language, saving a schedule when notifications are off, and other small issues.
