AI food journal for iPhone

A journal for what you eat.

Snap a photo of your meal. FitByte names the food, estimates calories, protein, carbs, fat and fiber, and writes it into today's page in seconds.

3 free scans every day Works with Siri Water tracking built in
Four ways to log

However you eat, it takes a few seconds.

Photo, barcode, a few typed words, or your voice. Every entry lands in the same daily journal with the same macro breakdown.

Snap a photo

Point your camera at a plate. AI identifies each food and estimates portions and nutrition.

Scan a barcode

Packaged food comes straight from a nutrition database. Not listed? Type its name and we'll estimate it.

Type it in

Write "two eggs and toast" in plain words. FitByte works out the rest.

Ask Siri

Log a meal or a glass of water without opening the app.
"Log water in FitByte"

Questions

Good to know

How accurate are the photo estimates?

FitByte identifies the foods on your plate and estimates portion sizes, so numbers are close rather than exact. You can edit any entry after a scan, and barcode scans use the product's published nutrition.

What is the health score?

Every scanned meal gets a score from 1 to 10 based on its overall nutritional balance. 8 to 10 shows green, 5 to 7 amber, and below that coral.

Can I change my daily goals?

Yes. The defaults are 2,000 kcal, 50g protein, 275g carbs, 78g fat, 28g fiber and 2 litres of water. Change any of them in your profile.

What happens after the free trial?

Premium starts on the plan you chose. Cancel from your Apple ID subscription settings at least 24 hours before the trial ends and you won't be charged.

Can I delete my account?

Yes. Deleting your account from the profile screen removes your account and your logged meals.
