SugarCurfew is now available on the App Store. It’s a small iOS app built around one simple idea: sugar should be easier to see before you drink or eat it.
It’s completely free — no subscriptions, no in-app purchases, no account, no ads.
Why I built it
Most nutrition apps want you to log everything: calories, macros, meals, portions. That’s a lot of friction for a question as simple as “how much sugar is in this bubble tea?”
SugarCurfew narrows the scope to just sugar, and makes the logging step as fast as possible. Point your camera at a nutrition label, a drink cup, or a dessert; the app suggests a category and a sugar amount; you confirm or adjust, then save. That’s the whole flow.
How it works
There are two ways to log:
- Photo Add — snap nutrition labels, drink cups, packaged foods, and desserts. OCR and recognition run on your device, and the result is always a suggestion: nothing is saved until you explicitly confirm it.
- Manual logging — when you already know what you’re recording, a quick-add path gets you there in a couple of taps.
Instead of dense nutrition tables, your day shows up as sugar cubes — simple cube-style counts that make daily totals, recent entries, and trends easy to scan at a glance. The app also remembers items you’ve confirmed before, so repeated drinks and snacks get faster to log over time.
Private by design
This part I care about a lot:
- Photos and OCR text are processed on your device — they are not sent to a third-party AI service or any cloud server.
- Confirmed records stay on your device. No account, no analytics SDKs, no tracking.
- Backups are manual export files you create yourself, and they don’t include photos.
The App Store privacy label is simply “Data Not Collected.”

SugarCurfew is young and I’d love feedback — recognition cases it gets wrong, categories it should know, or anything that feels slower than it should be. You can reach me at contact@kuroneko-cmd.dev or through the Support page.
