## What is Protein Tracker?

The AI protein tracker for muscle gain. Set your daily protein target, log what you eat in seconds, and watch the streak build — no spreadsheets, no math.

FREE — NO LIMITS, NO COUNTDOWN
• Daily protein target — auto-calculated from your weight, gender, and training frequency
• Unlimited logging — log as many meals and as many days as you want, free, forever
• Quick Add — one-tap log for your most-eaten foods
• Meal windows — every log is bucketed automatically, and the windows follow your training. Train in the morning and you get a Pre-Workout and Post-Workout window where they actually belong, alongside Breakfast, Lunch, Afternoon and Dinner
• Full history — every day you've logged, kept for good
• Progress analytics — your last 7 days and whether you're trending up, down, or holding against target
• Streak tracking — see how many days in a row you hit your target
• Lock-screen widget — daily progress ring without opening the app
• Apple Sign In — fast, private, no passwords

MUSCLEFUEL PRO
• Voice food log — say "two eggs, chicken breast" and we log it
• Photo scan — snap a meal and AI identifies the food and estimates the protein
• Weekly progress reports
• AI Nutrition Coach — ask it anything about your intake
$4.99/week or $39.99/year, both with a 3-day free trial. Auto-renews until canceled in Settings > Apple ID > Subscriptions.

## Version history (last 5 releases)

### 1.0.11 — 2026-08-27

No new features this time. We rewrote our App Store description so it's straight with you about what costs money and what doesn't.

Free, forever: unlimited logging, your full history, and progress analytics. We had been listing those as Pro features by mistake.

Pro: voice logging, photo scan, weekly reports, and the AI nutrition coach.

### 1.0.10 — 2026-08-23

Fixed: the kg/lbs switch in Settings now actually saves. The app also starts in pounds if that's what your region uses.

Fixed: a bug that could leave your profile empty after signing up, so your daily target was stuck at 0g.

Fixed: when a sign-in expired the app quietly stopped saving with no explanation. It now tells you and gets you signed back in.

### 1.0.9 — 2026-08-09

New: a 'More from PLAYRIOT' section in Settings — small, focused apps from the same team. Plus minor polish.

### 1.0.8 — 2026-08-05

“Leave a review” now opens the App Store directly — right where the stars are, no dead end. Plus small fixes under the hood.

### 1.0.7 — 2026-07-07

Smoother logging when you're between Wi-Fi signals at the gym — protein you log offline stays visible in your ring and history right away, and syncs automatically once you're back online.

Fixed a rare display bug where an unset daily target could show incorrect stats.

General reliability and polish improvements.
