Tap the + button on the home screen (or open the Log tab) and choose how to add your food: snap a photo of your plate, describe it in a sentence, or scan a barcode. Overheal's AI reads it and fills in the calories and macros for you. You can also search a food by name or enter custom nutrition values manually, then adjust the portion before saving.

They're two separate systems. Healthy actions — logging meals, hitting goals, completing daily quests — earn XP, which fills your health bar and raises your level. Your rank is earned through ranked play (duels and consistency) via Rank Rating (RR), and climbs a nine-tier ladder: Stone, Copper, Iron, Gold, Platinum, Diamond, Sentinel, Prismatic, and Zenith. Leveling up and ranking up are tracked independently.

It's a daily measure of eating quality on a 0–100 scale — a calorie-weighted average across your day, not a running total. It looks at things like macro balance, how close you land to your calorie target, your ratio of whole foods, sugar and sodium intake, and micronutrient targets. A score near 100 means an excellent day of choices.

Overheal estimates your Basal Metabolic Rate (BMR) with the Mifflin–St Jeor equation, then multiplies by an activity factor to estimate your daily energy expenditure. That figure is adjusted for your goal (lose, maintain, or gain) to set your daily calorie and macro targets.

Yes. Open the day or the Meals view, tap a meal to adjust its portions or items, or swipe / use the trash icon to delete it. Your totals, health bar, and Purity Score update immediately.

Missing a full day normally resets your streak — but everyone gets one free Streak Shield each week that automatically protects your streak so a single off day doesn't wipe your progress.
