Privacy-first nutrition scanner · iPhone

Nutrition, made clear. And kept to yourself.

Scan a barcode or photograph a label. Theli reads it in a beat — calories, macros, the whole panel — and logs it. No account. No ads. No tracking. Your food diary never leaves your phone.

The loop

Scan. Confirm. Log. That's the whole app.

Two ways in, one calm review screen, and it's in your day. No menus to wrangle, no profile to build first.

01 / Barcode

Point at the barcode

Theli looks it up in Open Food Facts, with a USDA fallback for US products that aren't there yet. Facts appear, scaled to your serving.

02 / Label

Or photograph the label

No barcode? Fresh, local, or imported food? Snap the Nutrition Facts panel. Apple's on-device Vision reads it — the photo never leaves your phone and is discarded after parsing.

03 / Log

Check it, then log it

One review screen. Adjust the serving and every number recomputes instantly. Tap to log. It lands in today's diary, grouped by meal, totaled against your targets.

Why Theli is different

Most nutrition apps are data businesses. Theli isn't.

✓
No account, everOpen the app and start. No sign-up, no email, no profile to hand over before you can scan.
✓
No ads, no analytics, no trackersZero third-party SDKs. Nothing watches how you use the app or what you eat.
✓
Labels read on-devicePhotos are processed by Apple's Vision framework on your phone and discarded. No image is ever uploaded or stored.
✓
Your log stays localYour food diary lives in on-device storage only. There's no Theli server, no cloud sync, no backup we can read.
✓
The only thing that leaves is a barcode numberScanned barcodes go to Open Food Facts / USDA purely to look up a product. Nothing personal rides along.
✓
Apple Health is opt-in & write-onlyIf you ever turn on Health sync, Theli only writes entries you logged. It never reads your health data.
Pricing

Free. The whole thing.

no paywall

Every feature is open — scanning, label OCR, your daily log, targets, history. Theli is built as a labour of care, not a funnel. If it earns a place on your home screen and you'd like to chip in toward the Apple Developer fee and keep it growing, there's a small, entirely optional tip jar. That's the only thing money touches.
