Protein Tracker is the simplest way to hit your daily protein, fiber and iron goals - track one, two or all three. Most people fall short on at least one of these. Too little protein slows muscle gain and recovery. Too little fiber shows up as bloating and sluggish digestion. Too little iron leaves you tired and foggy. The fix is simple - know what you're eating. Protein Tracker makes that easy. HOW IT WORKS 1. Choose what to track: protein, fiber, iron, or any mix. 2. Set a daily target for each - from your body weight and goal for protein, your age and sex for fiber and iron - or type in your own number. 3. Add what you ate: search the food collection, snap a photo of the meal, scan a barcode, say it out loud, or enter a custom food. One log fills in every nutrient you track. 4. Check the portion and the amounts, adjust anything that looks off, then save. 5. Watch your rings fill, and use the weekly calendar to see how each day compares with your targets. FEATURES - One searchable collection of high-protein, high-fiber and iron-rich foods, with a filter for each - Photo, barcode, and voice logging with AI, and every result stays editable before you save - Logging food to any of the last seven days, with an editable time on every entry - Favorites and recent custom portions for the foods you eat often - Daily history and trends for each nutrient, streaks, achievements, and challenges - Goal and unit settings you can change whenever your training or diet does DATA AND AI No account, no sign-up, no ads. Your food log is stored on your device. Photo, barcode, and voice logging send that input for AI processing and need an internet connection - typing and searching stay on your device. AI estimates are approximations, so review them before saving. Protein Tracker is a tracking tool, not medical or dietary advice. That's it. A minute to set up, and you'll finally know exactly where your protein, fiber and iron stand - every single day. Questions or ideas? Hit the contact link in Settings and I'll get back to you fast. Food logging and tracking are part of Protein Tracker Pro, available as an in-app subscription or a one-time purchase.
