Simply Gym for Android
Pick a program, choose your training days and equipment, and Simply Gym plans the whole block. During a workout, every planned set is pre-filled from last time — tap any value to change it with the built-in number pad, then swipe the row to check it off. After the final set of an exercise, rate how it felt; that rating guides that exercise's next suggestion.
It's per-program now. Change it during setup (Duration step) or any time in the program editor.
Settings → Export & backup → Save a JSON backup, copy the file to the new device, install Simply Gym, then Restore. Everything — programs, history, notes — comes back.
Weight programs → Build a custom program. Add days, add exercises (cardio included), set sets, reps, rest, supersets and drop sets, and drag to reorder. Start it like any other program.
Cardio programs → pick one of the ready-made plans or build your own: steady sessions, intervals with an on-screen timer, outdoor and classes. Quick cardio on Today logs a one-off session, and can start from any day of a plan.
Settings → Premium → Restore purchase, with the same Google account that bought it. Billing entitlements only work on Play-installed builds.
