The Today screen: next action, energy, protein, carbs, fat, water and exercise

Everything you eat, everything you do, in one place

Stop guessing. BYOHack turns meals and Health data into clear, daily nudges.

Snap a meal

Take a photo or describe what you ate. A.I. estimates energy, protein, carbs, fat and more. Save favourites to re-log with one tap.

See every nutrient

Track vitamins, minerals, sugar, sodium, fibre and water against your own targets, with colour bars that show what's behind.

Menu ideas that fit

Get breakfast, lunch and dinner suggestions built from your meal history and what you still need today.

Health Track

Weight, body fat, cardio fitness, sleep, steps and mood from Apple Health, by day, week, month or year, with plain-English explanations.

Health Coach

Ask for keto targets, a high-protein swap or a weekly adjustment. The coach knows your targets and recent days.

Private by design

Your logs, targets and Health data stay on your iPhone. No ads, and we never sell your data.
