Track protein without turning meals into homework. Buff Kitty is a protein-only tracker for lifters who care about hitting one number every day. No calorie diary. No macro spreadsheet. Just your daily protein target, fast logging, and a gym cat that reacts as you get closer. Set your goal once, then log protein in seconds: - Quick-add the amounts you log constantly, straight from the dashboard - Type the grams when you already know them - Say what you ate when typing is annoying - Snap a meal photo and get an editable AI estimate - Scan a barcode for packaged food - Every estimate is yours to edit before it saves - Today's total, what's left, your streak, and recent entries on one screen Works the same whether you're bulking, cutting, maintaining, or recomping. Build a streak by hitting your protein target, and choose the reminder settings that work for you. Sign in with Apple or Google if you want to back up your protein target, food log, and Kitty progress, then restore them when you reinstall or change phones. Sign-in is optional. Manage your backup, email preferences, and account deletion in Settings. Buff Kitty is a subscription app. Setting your target is free, and a subscription unlocks tracking, the AI estimates, streaks, and the home-screen widget. AI estimates can be wrong, so check them before you save. This is a tracking tool, not medical advice. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

Pro Cal and Buff Kitty Protein Tracker both sit at 4.8 stars, but that hides the real split: 100% of Buff Kitty Protein Tracker's written reviews are positive against 36% of Pro Cal's. Buff Kitty Protein Tracker also leads on monetization model (freemium vs subscription) and update cadence (weekly vs every 2 weeks). Pro Cal's advantage is ratings volume (14K vs 8) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
