Yes. Gainz is offline-first, so no signal is no problem. Workouts save locally, and optional sync catches up when you're back online. Perfect for basement gyms, outdoor training, or gyms with bad reception.

After finishing a workout, tap "Save as Template". Name it, and it's ready. Next time, just tap your template to start. You can also create templates from scratch in the Templates tab, or browse our library of pre-built programs.

Swipe right on any set to log it instantly. Or tap to enter custom weight and reps. The app pre-fills your last session's numbers so you just confirm or adjust.

After logging a set, the rest timer starts automatically. You can customize rest periods per exercise in Settings. The timer works even when your phone is locked.

Go to the History tab to see all past workouts. Tap any workout to see full details including sets, weights, and notes. You can also view progress charts for each exercise.

First, make sure you're running the latest version. Go to App Store → Updates. If the issue persists, try closing and reopening the app, or restart your device.

Gainz saves workouts locally first, so a weak connection should not block logging. If data appears missing, avoid reinstalling the app and contact support with your device and app version so we can help safely.
