Why Lyto

Tracking that gets out of your way.

Three ways to log a meal in seconds — no databases to dig through, no weighing every gram.

Speak or scan

Describe a meal out loud, or scan a barcode for exact label values from a 4M+ food database.

FAQ

Questions, answered.

How does Lyto count calories from a photo?

Snap your plate and Lyto's AI recognizes the food and estimates calories and macros — protein, fat and carbs — in seconds. You can adjust the portion or ingredients anytime.

How accurate is it?

AI estimates are close for most everyday meals and give you a reliable daily picture without weighing every ingredient. For packaged food, scan the barcode to pull exact values from the label.

Is Lyto free?

Yes. You can log food, scan barcodes, and track weight, water and fasting for free. Premium unlocks unlimited AI photo and voice scans.

Can I log without taking a photo?

Absolutely. Scan a barcode, search the food database, or just describe your meal out loud — Lyto logs it for you.

Does it track fasting and steps?

Yes. Run a 16:8 or custom intermittent-fasting window and see your steps and active calories from Apple Health, all alongside your food diary.

Is my data private?

Your food diary, weight and health data stay on your device and your private iCloud. Photos you scan are sent only for recognition and aren't stored afterwards. No ads, and we never sell your data.

Which devices are supported?

Lyto runs on iPhone with iOS 16 or later. Apple Health sync keeps your steps, weight and activity up to date automatically.

How do I cancel Premium?

Premium is billed through the App Store. You can manage or cancel anytime from your Apple subscription settings — access stays until the end of the billing period.
