Log dinner by pointing your camera at it.
Cut is an iPhone fat-loss tracker built around two ideas: logging should be one photo and one tap, and your maintenance calories should be measured from your own data, not guessed from a formula.
No account. No ads. Your food and weight data stays on your phone.
The logging problem
One photo, one tap.
Every food tracker fails the same way. Logging is friction, so you stop logging, so the data stops being true, so the app stops being useful. Barcode scanners, database search and serving-size pickers make it worse, not better: four taps where a photo could be one.
So Cut is built around the camera. Photograph the plate, get a description with calories, protein, carbs and fat, correct anything that looks off, save. An estimate that is slightly off but logged every single day beats a database that is exact and abandoned by Thursday.
The estimate also tells you how sure it is. A low-confidence guess is flagged above the numbers, before you read them, and any field you change is marked as edited. For packaged food, where a photo can't see the label, there is a barcode scanner and plain manual entry.
Weight
Your scale weight is mostly noise.
Day-to-day weight swings a kilo or more on water, salt, sleep and the size of last night's dinner. None of that is fat. So Cut never headlines the raw number. It shows an exponentially smoothed trend, where one strange morning barely registers and a real change shows up as a line you can believe.
Metabolism
Maintenance calories, measured instead of guessed.
Most trackers estimate your daily burn from height, age and an activity multiplier. That is a population average wearing your name. Cut derives it from what actually happened: what you logged eating, against how your trend weight moved.
tdee = mean intake − (trend weight change × 7700 ÷ days)
7,700 kcal is roughly one kilogram of body fat. Ate 2,000 a day and the trend fell anyway? You burn more than 2,000. That is the whole trick.
The result is a number that belongs to you. It updates itself as you lose weight, and it deliberately ignores your watch's calorie-burn estimates: energy balance already includes your movement, without inheriting the watch's error.
Your daily target comes off that number, with the deficit sized as a percentage of your bodyweight, so the cut gets gentler as you approach the goal. The target also has a hard floor it will never go below, whatever the arithmetic says.
And until there is enough of your own data to measure from, Cut falls back to the standard formula and labels it as a fallback, rather than dressing a guess up as a measurement.
Tone
Built not to shame you.
These rules are written into the code, not the marketing:
- Food is morally neutral. Nothing is earned, cheated or burned off. Going over target is information, nothing more.
- The calorie target never drops below a hard minimum, no matter what the maths suggests. The app will not talk you into a crash diet.
- An unlogged day is missing data, not a zero-calorie day. Gaps never distort your averages, and a quiet week is never read as fasting.
- The coach refuses the bad stuff. It will not help you eat below the floor, will not frame exercise as punishment for eating, and does not give medical advice.
Also in the app
The rest of it.
- A coach that has read your log
- Ask questions of your own history: why did I stall this week, how is protein trending, what should I eat tonight. Answers come from your logged data, and when the data is too thin to say, it says so instead of guessing.
- Voice logging
- Tell the coach what you ate or what you weighed and it logs it, then shows exactly what it recorded, with an undo button.
- Apple Health, both directions
- Reads weight, steps, active energy and workouts. Writes calories, protein and hand-entered weigh-ins back, so Health stays the source of truth.
- Fridge photo
- Photograph what's in the fridge and get dinner suggestions that fit inside what's left of today's target.
- Barcode and manual entry
- For packaged food, where photos are weakest. Barcode lookups come from Open Food Facts.
- One quiet reminder
- A single daily notification to weigh in and log. That's the only one it sends.
