Scan
Camera and barcode
Point the camera at a food label and Crumb reads it. A corner-guided scanner picks up barcodes live as you turn the pack.

Read the label before you eat it.
Crumb is a food diary for people living gluten free. Point the camera at a label or a barcode and it returns a gluten read with the reason behind it. When something is uncertain, it says so instead of guessing.

What a read looks like
The reason, the uncertainty, and what to check.
Ingredients Wheat flatbread, chicken, marinade seasoning, tahini sauce…
Crumb · ingredient readHigher risk
The wrap bread is a clear gluten source.
Uncertainty: marinade and shared prep. Not a safety determination; verify the label. For restaurant food, confirm with the venue.
Data: saved to your Crumb log only after consent; /delete erases it.
An example read from the Crumb chat. Real reads name what needs checking, not a verdict you have to trust blindly.
The Android app
Six mechanics, in the app you install.
Everything here ships in the production build on Google Play: com.nomoi.crumb, version 0.5.16.
Lexicon
It knows the traps
A conservative ingredient lexicon that catches the things people miss: shared fryers, malt vinegar, soy sauce, oats, and "gluten free" claims from a gluten kitchen.
Standards
Regional rules
Regional labelling rules are applied, including the stricter Australian and New Zealand (FSANZ) gluten-free standard.
Log
The meal behind the read
Log a meal by chatting or by choosing a photo. Crumb estimates calories and macros so you can track daily energy.
Balance
Intake against burn
Connect Health Connect and Crumb reads your activity and calories burned from Garmin, Fitbit, Whoop, Samsung Health, Oura or Google Fit.
Control
Your log, your call
Edit or delete individual meal logs inside the app. A read that sits in your history is a read you can take back out.
The floor
What Crumb will not do.
- Crumb is not a medical device. It does not diagnose, treat or prevent any condition.
- Crumb never claims a food is guaranteed safe. It flags what to verify and gives the reason.
- Payment never changes the gluten-risk answer. The gluten-risk core stays free.
Two ways in
The app on your phone, or the chat in your pocket.
The Android app
Scan labels and barcodes with the camera, log meals by chat or photo, track calories and macros, and connect Health Connect to see intake against burn. Edit or delete any log inside the app.
The Crumb chat
Send a photo, a label, a menu line or a voice note and get a gluten read with the uncertainty named. Nothing is logged before you consent, and /delete erases it.
Gluten-risk reads stay free. Adults can add a calorie layer for $1 in the first month, then $5.99/month, or $49/year. Paying for it never changes the gluten-risk answer.
Start with one label
Free to read. Honest about the rest.
Install Crumb from Google Play, or send your first meal to the Crumb chat and see what it says before you commit to anything.
