Diary, water and weight
Food diary app: log meals, water and weight in seconds
Calorie Genie is a food diary app for iPhone and Android that logs meals from a photo, water in one tap and weigh-ins in a single line. Every entry counts against your daily calorie and macro target, and your history is there for 7, 30 or 90 days. Free to download.
Meals go in through the AI calorie counter: photograph the plate and the calories, protein, carbs and fat are logged for you. Your daily target is set during setup; check it against the calorie calculator if you want to see the working.
What is in the diary
Everything a food diary should track, on one screen
The daily log
Calories remaining, protein, carbs and fat against your target, water so far and today's quest, all on one screen. Meals are grouped into breakfast, lunch, dinner and snacks.
History by day and meal
Scroll back through every day with its total against target and each meal's calories, and open any entry to see or edit the ingredients.
Water in one tap
Set a daily water goal, then add 250 ml, 500 ml, 750 ml or a litre with one press, or type a custom amount. The pup cheers you on.
Weigh-ins in a line
Type today's weight and save. Recent weigh-ins show the change since the last one, so the trend is obvious without a spreadsheet.
Why it sticks
Why a photo food diary beats typing one
Most food diaries are abandoned within a couple of weeks, and the reason is nearly always friction. Here is what changes when the camera does the logging.
Logging takes seconds, not minutes
A photo replaces the search box. Genie estimates each ingredient and portion; you glance, adjust if needed and save. Packaged food is scanned by barcode.
Nothing to remember later
Because logging is quick, it happens at the table rather than at bedtime from memory, which is where most food diaries go wrong.
Any food, any cuisine
Home cooking, takeaways, restaurant plates and foreign supermarkets all work because the app recognises the meal instead of searching a fixed database.
The trend, not just today
History and weigh-ins sit together, so you can see whether a week of logging moved the scale and by how much.
Keep it going
A diary that rewards you for filling it in
Each logged meal, glass of water and weigh-in completes a step on the daily journey. Steps earn gems, streaks build day by day, and 26 badges mark milestones such as your first scan or a consistent week.
The consistency grid in Achievements shows your active days over 7, 30 or 90 days, so a good month is visible at a glance and a missed day is just a gap, not a reset of everything.
