Amy showing a typed food line with estimated calories

How it works.

Amy keeps the main loop short enough to use while eating: capture a line, check the estimate, and keep moving.

1 Write what you ate

Use plain text, a photo, a label, dictation, barcode lookup, or a saved meal from the Today screen.

2 Review the result

Amy attaches calories and macros to the visible food line so mistakes are easy to spot and edit.

3 Keep the diary local

Your goals, saved meals, corrections, imports, exports, and daily log stay on the device.

Built because Android needed this.

I wanted the fast note-like logging flow from the iOS Amy app on Android, so I built Open Amy and am sharing it free. It is early, public on GitHub, and shaped by real tester feedback.

Small on purpose

The first action should be writing what you ate. Stats, streaks, widgets, barcode lookup, and AI estimates support the daily log instead of replacing it.

Built in public

The app, releases, and issue tracker are on GitHub so testers can follow progress, report bugs, and contribute improvements.

Fast logging without the account wall.

The core loop is deliberately small: one line per food, AI-assisted calorie and macro estimates, local storage, and capture shortcuts when typing is not enough.

Text-to-calorie lines

Type a meal the way you would write it in a note. Amy keeps the text visible and attaches calories to the line.

AI logging from text, photo, label, and voice

Bring your OpenRouter key and Amy can estimate calories and macros from plain text, meal photos, nutrition labels, and dictation.

Open Food Facts barcode lookup

Scan packaged foods through Open Food Facts instead of a proprietary nutrition database.

Local data by default

No account is required. Diary data, goals, saved meals, corrections, imports, and exports live on the device.

Android widgets

Keep daily calories and mini Today actions close to the home screen for fast logging.

No ads or tracking SDKs

Amy has no Firebase, no Play Services dependency, no account wall, no subscription, and no ad SDKs.

The app stays close to the log.

Stats, streaks, capture, and settings are useful, but the daily note stays the center of gravity.

Looking for Android testers.

The most useful feedback is concrete: device model, Android version, launcher, APK version, and exactly what broke or felt slow.

Install and launch reports on different Android versions and OEM devices.
Small-screen, large-font, and tablet layout issues.
Widget resize behavior on real launchers.
Barcode misses or bad Open Food Facts matches.
AI logging misses from text, photos, labels, or dictation.
Export/import restore problems.
