The Gym Buddy home screen: this week's training days, today's Leg Day ready to start, and a body-weight chart falling from 82.5 kg toward a 77 kg goal.

Start with a plan, or write your own.

Four starter programs load in one tap: Push/Pull/Legs, Upper/Lower, Full Body and 5×5. Put any routine on any weekday, stack two routines on the same day, pair exercises into supersets, and move a session when the week gets in the way.

The Plan screen: a week schedule with Push Day on Monday, Pull Day on Wednesday and Leg Day on Friday, and rest days in between.

Log a set with one tap.

Weights and reps come prefilled from last time. Tick the set and the rest timer starts, with a quick −15 s, +15 s or Skip when you're ready early.

Every set type you use: warm-ups, drop sets, rest-pause, left and right sides, timed holds and cardio.
Effort, if you track it: rate sets as RIR or RPE.
Weigh in on the way in: a quick check-in before each workout keeps your body-weight curve honest.

The rest timer counting down from 1:28 at the bottom of the workout screen, with −15 s, +15 s and Skip buttons.

Your next weight, already worked out.

Gym Buddy reads what you actually lifted last session and sets today's weight, then tells you why. Hit every rep and the load goes up. Miss, and it holds. Keep missing, and it deloads.

Linear progression for steady beginner gains.
Greyskull LP with its AMRAP last set.
Double progression through a rep range before adding weight.
Added time for planks, holds and other timed work.

A Leg Day workout: Barbell Full Squat with last session's sets and the note 'Linear progression: every rep last time, 5 kg more', with 92.5 kg prefilled for each set.

See what you trained. And what you skipped.

Muscle balance maps your sets onto the body, so a missed leg week shows up in grey. Switch to fatigue to see what's still recovering, or strength to see where you stand.

A year at a glance: every training day on one activity heatmap.
Progress per exercise: top sets and estimated one-rep max over time.
Body weight against the goal you set.

The Stats screen: 32 workouts, 9 this month, a 13-week streak, 1.2 kg lost in 30 days, and a 12-month activity heatmap.

Muscle balance for the week on a front and back body map: shoulders, biceps and chest in bright green, legs in grey, with sets per muscle listed below.

1,324 exercises, each one animated.

Search by name, filter by body part or by the equipment you own, or pick a muscle and see everything that trains it. Every exercise has an animation, step-by-step instructions and a one-rep-max calculator. Missing one? Add your own.

The exercise library: a search field, body-part and equipment filters, and a list of exercises with thumbnails and an Add to plan button on each.

An exercise page for the 3/4 Sit-Up with an animated demo, muscle tags, Add to my plan, an estimated one-rep-max calculator and numbered instructions.

The whole app in 60 seconds.

Questions

Is it really free?

Yes. There are no ads, no subscription and no in-app purchases.

Is installing an APK safe?

Download it only from this site, and if you want to be sure, compare the file's SHA-256 with the one listed above. Gym Buddy asks for two permissions, and only when you use the feature: the camera to scan a gym membership card, and notifications for workout reminders and the rest timer.

What happens to my data if I lose my phone?

Your log lives only on your phone, so keep a copy. In Settings you can export a backup file, or turn on auto-backup to write one to a folder that your cloud-sync app of choice picks up. Importing that file on a new phone brings everything back.

Can I bring my history from another app?

Yes. Gym Buddy imports CSV exports from Strong, Hevy and FitNotes, and can pull your Hevy history directly with a Hevy Pro API key.

Is there an iPhone version?

Not yet. Gym Buddy is Android-only for now.

Which languages does it support?

English, German (with a Swiss variant), Spanish, French, Italian, Portuguese (Portugal and Brazil), Polish, Turkish, Russian, Chinese, Korean, Hindi, Thai and Hungarian.

Is Gym Buddy open source?

Yes. It's free software under the GNU AGPL 3.0, built on the open-source openGym project.
