About Barktein

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. Where Apple offers it, eligible subscriptions may include a free trial shown clearly on the purchase screen.
