Barktein tracks your daily protein the effortless way: snap a photo of your meal, scan a barcode, or just describe what you ate — and Rex, your cartoon gym dog, reacts, levels up, and keeps you coming back. Whether you're building strength, keeping up healthy habits, or simply aiming to get enough protein every day — Barktein makes the habit stick, no spreadsheets required. LOG WITHOUT TYPING • Photo estimates (new): take or choose a meal photo and get an AI-powered, fully editable estimate of protein, calories, carbs, and fat. Optional and consent-based — first 3 free, unlimited with PRO. • Barcode scan: point your camera at any product. Known items log instantly from your own learned pantry; unknown ones can be filled by Open Food Facts lookup or label values you enter once. • Describe your meal: type "2 eggs and a cup of rice" for an instant on-device estimate — works offline. • Quick-add presets, repeat-last, and pinned favorites for everything else. REX EVOLVES WITH YOU Hit 70%+ of your goal for a valid day. Stack valid days and Rex levels up: Regular → Pumped → Legend. Unlock poses, free gear on the ladder, and PRO collectibles when you're ready. STREAKS & PROGRESS See your streak, a 7-day chart, this-week stats, a monthly valid-day calendar, and a weekly recap when last week wraps. BARK REMINDERS Local notifications (not cloud push) nudge you to log — and they're smart: they stop when you hit your goal and can pause for the day. Specific times and quiet hours with Barktein PRO. PRIVATE BY DESIGN Your logs stay on your device. No account required. Photo estimation is optional: photos are used only for the estimate you request and are never stored by us. All numbers are informational estimates — not medical or dietary advice. Barktein PRO unlocks unlimited photo estimates, custom reminder schedules, premium Rex gear, and more collectibles. Annual and monthly subscriptions auto-renew unless canceled; Lifetime is a one-time purchase.

All of it works offline with your own learned pantry, and you can turn online lookup off in Settings. More in this update: • Smarter bark reminders — they stop when you hit your goal, hold off right after you log, and can be paused for the day • Repeat-last chip and pinnable Quick Add favorites for faster logging • Rex's Protein Picks — product ideas matched to what's left of today's goal • Delete entries and meals right from the edit screen Your data still lives on your device.

Describe your meal in plain words — like "a restaurant burger and fries" or "two eggs, toast, and a handful of almonds" — and Barktein estimates the protein, calories, carbs, and fat. Review and tweak every number before it hits your log. Also new: smart protein suggestions on Home that show how to close today's gap, built from foods you actually log.
