Free to download. Try Hellog free for 7 days, then keep it for life with a one-time purchase. No ads, no subscription, no account. A gym log with no ads, no subscriptions, and no sign-up. Check off a set in one tap, and your rest is timed for you. Rate the machines at your gym, and create any exercise that isn't on the list. Hellog focuses on two things: logging your sets and timing your rest. There are no ads and no subscriptions, and you can start right away without creating an account. BRAND AND EQUIPMENT RATINGS Every gym has different equipment, and even for the bench press, some machines just fit you better. Add the equipment you've used with its brand and model, then leave a rating and a note. Your equipment list is sorted by rating, and when you save equipment in a routine, your next workout starts on that same machine. CREATE YOUR OWN EXERCISES Enter a name, then choose the equipment, body part, target muscle, and how it's measured. Your new exercise is ready. Custom exercises are logged just like the built-in ones. ONE TAP PER SET Pick your weight while looking at last time's numbers. Check off a set and the rest timer starts right away. The time left shows on the Lock Screen and in the Dynamic Island, and a sound lets you know when rest is over. Tap the set number to mark warm-up (W) and drop sets (D). In regions that use pounds, such as the US, Hellog starts in lb. You can switch between kg and lb anytime in Settings. PR ALERTS When you finish a set and your estimated one-rep max (e1RM) beats your previous best, you get a PR alert. RECOVERY ON A MUSCLE MAP Fatigue for each body part shows up as color on a muscle map, so you can pick today's muscle group at a glance. STRENGTH GAINS IN NUMBERS See your weekly volume and how it changed from last week. ROUTINES THAT ARE EASY TO UPDATE If your weight, reps, order, or equipment differ from your routine, Hellog asks at the end of your workout whether to update the routine. Press and drag an exercise card to reorder it. YOUR RECORDS STAY ON YOUR PHONE Each set is saved to your phone the moment you check it off, so your log keeps going even where the signal is weak, like a basement gym. Hellog has no server collecting your records, so not even the developer can see them. Turn on iCloud sync in Settings to keep records matched across devices that use the same Apple Account. DATA EXPORT Export your workouts, routines, body measurements, and equipment ratings as a single JSON file. FREE TO START, PAY ONCE Hellog is free to download, and you can try it free for 7 days. After that, a one-time purchase unlocks Hellog for life. There's no subscription. When the trial ends, your records stay visible; only starting a new workout is locked.
