Describe it
Type what you ate and how much. Amounts matter: "a bowl of pasta" could be 400 kcal or 900.
An estimate you can check
A photo can't weigh your food, so a scan is a starting point. Tracker Turtle shows how it got there and lets you correct it. Nothing goes in your log until you press Save.
Estimated from your photo.
Assumed the chicken was cooked with a little oil. Check the numbers before saving.
It says what it assumed
Each scan comes with a short note on the guesses that move the numbers most. If the photo was hard to read, it tells you the estimate is rough.
Oil and dressing get their own line
Things that are usually there but hard to see are listed separately, so you can take one out if it wasn't on your plate.
Wrong kind? Pick the right one
When it can't tell white rice from brown, or how lean the beef is, it offers the likely alternatives with their numbers.
For meals you can't photograph
Scan the barcode
Packaged food is looked up in Open Food Facts, an open product database that anyone can edit. Check the numbers against the label before you save.
Log it again
A food you've logged before goes back in with one tap. You can also type the numbers in yourself.
Every meal counts down from your target
Answer four questions and Tracker Turtle works out a daily calorie and macro target from your goal and your weight trend. It shows each step of the math, and you can change any number or enter your own.
- Meals stay in order
- Entries group into breakfast, lunch, dinner and snacks, or a name you type.
- Any day can be fixed
- Go back to an earlier day to add what you forgot or change what you logged.
The target is an estimate from a standard formula, Mifflin-St Jeor. It is not medical or dietary advice.
The scale lies. The trend doesn't.
Your weight swings from day to day with water, salt and sleep. Tracker Turtle averages the last seven days and tells you whether you're on pace for your goal.
- A minute each morning
- Type your weight on a number pad, then take front, side and back photos. Your last shot is ghosted over the camera so you stand in the same spot.
- See the change
- Compare any two dates with a slider, or play a pose back as a timelapse.
- Photos stay private
- They are stored inside the app behind Face ID, and never in your camera roll.

What happens to your photo
- A meal photo goes to our server and on to Anthropic's Claude, which estimates it. We don't keep the photo once the estimate comes back.
- Your weigh-ins, progress photos and food log stay on your iPhone and in your own private iCloud. We can't see them.
- There are no ads and no tracking. We hold your account details and a count of your scans, and nothing about what you eat or weigh.
Questions about scanning
Setup, syncing and subscriptions are covered on the Support page.
How accurate is a meal scan?
A scan is an estimate made from a photo, and it can be wrong, most often about portion size. Every scan opens on a screen where you can change any food, portion or number before saving. A photo from above, in good light, with the whole plate in the frame gives it the most to work with.
What if it gets my food wrong?
Tap the food's name to pick another kind, take out anything that wasn't there, or type over a number. If it's far off, try another photo or enter the meal by hand.
Is there a limit on scans?
Each account gets 20 scans a day. The count starts over once a day, and the app tells you when. Logging by barcode or by hand has no limit.
What does the estimating?
Anthropic's Claude. It looks at your photo or reads your description and lists the foods and portions it finds. Tracker Turtle adds up the totals.
Do I need an account?
Yes. You sign in with Apple or with an email address. The account carries your subscription and your daily scan count.
Which phones does it work on?
iPhone, on iOS 17 or later.
Is this medical advice?
No. Tracker Turtle is a tracker. Calorie and macro targets are estimates from a standard formula. If you have a history of disordered eating, talk to someone you trust before weighing yourself or counting calories daily.
