Auxa plans every set for you. Bring the plan you already follow, or tell Auxa your goal and the days you can train and it builds one. Either way, each set's weight and reps are ready when you walk in, worked out from your last session. Hit the target, and logging the set takes one tap. Auxa is free for good: logging, your plan and your history. YOUR PLAN OR OURS Already follow a plan? Build it day by day, turn workouts you've logged into days, or paste or photograph it. It is read on your iPhone and never uploaded. You keep your days and lifts; Auxa sets the weight and reps of every set and moves them up as you get stronger. Or let Auxa plan your week from your goal and your gym, and switch any time. EVERY SET, PLANNED Each set is planned so you finish with 1 rep left. Earn another rep or more weight, and the next session has it filled in, with a short note saying why. New to a lift? Your first set finds your working weight. Back after a break? Your first session back starts a little easier. TOOLS FOR THE GYM FLOOR A plate calculator shows what goes on each side of the bar. Warm-up sets come before your working sets. Rest starts on its own and counts down on the Lock Screen, in the Dynamic Island and on Apple Watch. Swap a lift for today or for good from over 550 exercises your gym can do. Save any workout to run again. LIFTING AND CARDIO, ONE PLAN Easy, interval and long cardio sessions are planned around your lifting, built on what you enjoy: running, cycling, rowing, swimming, walking and more. Change today's cardio in one tap, or log extra cardio on any day. Split your week as full body, upper and lower, or push, pull, legs. SEE YOUR PROGRESS A Record when you beat the plan, an Up when you hit it. A strength chart and full history for every lift, sets per muscle on a body map, your goals, and your streak. Every six weeks, a recap shows what moved. Tap any finished workout to see it again: a run's route on a map, its splits and its heart rate. Share a workout or a run as a story or a post. TRAIN WITH YOUR CREW Start a private crew for the people you train with, up to 20, and invite them with a link or a code. Each workout becomes a post your crew can give props to and comment on, with a record or a comeback called out. Runs show their route, with the start and end hidden. The Board compares everyone against their own plan, by week, month and year. You choose what each crew sees, and everything starts off. Crews are for adults 18 and older. YOUR LOG, YOUR WAY Edit any past workout or cardio session. Make your own lifts. Keep a note on a lift, like seat 4, pin 3. Coming from another app? Import your history from its CSV export. ANY GYM, ANY UNITS Save the places you train, and Auxa rebuilds the session from the equipment there. Set any lift to pounds or kilograms, with targets in real plate and dumbbell steps. Distances show in miles or kilometers. APPLE HEALTH, OPTIONAL Auxa can read workouts and their routes, the distance of runs, rides, swims and rows, heart rate, heart rate variability, resting and sleeping heart rate, sleep, bodyweight, VO2 max, and the calories and protein your food app logs. It saves each lift session to Apple Health as a workout. With an Apple Watch, the report shows your heart rate through a lift and the highest reading on each exercise. A Garmin works through Apple Health too. PRIVATE BY DESIGN No ads. No tracking. Your training log stays on your iPhone, and nobody else can see it, including the developer. You can save a copy of it at any time. Crews use a free account through Sign in with Apple, asked for only when you start or join one, and what you share with a crew is kept on Auxa's server so your crew can see it. Your cardio and heart rate are shared only if you turn them on. Your sleep, recovery, bodyweight and nutrition never are. Auxa is not a medical device and does not give medical advice.
