Quick comparison table

Protein Tracker: Muscle Gain tops this table for speed and simplicity. No ads, no accounts, just a clean protein count.

1. Protein Tracker: Muscle Gain

Best for: no-fuss daily protein logging with zero ads.

Most protein calculators bury you in calorie menus or demand an email before you log a single gram. Protein Tracker does the opposite. You set a daily target once, then tap a quick-add button or search a local food database. Each entry takes under five seconds.

The home screen widget pushes speed even further: one tap logs a favourite food without opening the app. A clean progress ring shows grams consumed and what’s left, so you know at a glance whether you’re on track.

• Logs protein in seconds via a distraction-free interface, with no calorie clutter or social feeds.
• Home screen widget and weekly streak calendar keep logging quick and consistent.
• All data stays on your device: no account, no data collection, no ads, ever.
