Snap a meal, skip the search
Photograph the plate and Joules names what is on it and estimates the calories and macros. No hunting through a database for “chicken, grilled, 100 g”.

With a food diary you can see what you actually eat rather than what you remember eating. Whether you want to lose weight, put it on, or simply eat better, having the numbers in front of you is most of the work.
What it does that a spreadsheet cannot
Calories and macros in one view
Eaten, burned and what is left, with carbs, protein and fat tracking alongside. The number you care about is the first thing on screen.
A health score, not just a total
Every meal gets scored on protein, fibre, sodium and saturated fat, with a line on what to pair it with. Hitting your calories badly is still hitting them badly.
Fasting, steps and habits built in
A fasting timer that shows when fat burning starts, plus step and workout streaks. One app instead of four.
Reads your watch, does not double-count
Steps, active energy and workouts come in from Apple Health, Whoop, Garmin or your watch — and a workout only counts once you confirm it.
Watches the trend, not the morning
Weigh-ins smooth into a line with the goal marked on it, so a heavy Monday stops feeling like a verdict.

Not sure what your daily target should be? The calorie calculator works it out from your height, weight and activity, and the short quiz goes further — it asks about your pace, how you eat and what usually derails you, then sets the macros to match.
