Bein

Measure what your body does with what you eat.

Burnin works out your real metabolic rate from what you log and what you weigh. Cookin keeps the recipes your meals come from. Both are free, and their AI runs on your phone.

Both free. No account. iPhone and Android.

The architecture

One AI model, shared by both apps

Both apps run a language model on your phone. The model is about 2.4 GB, so the apps share one copy instead of downloading it twice.

B Burnin C Cookin 2.4 GB one model, on your device

Install both and the second one finds the model the first already has and uses it in place. On Android the app holding the model runs the inference for the other, and only apps signed with our certificate can call it. On iPhone it's a shared App Group. Either way, the inference happens on your phone. If a phone can't run the model, the AI features are switched off and logging stays manual; nothing is sent to a cloud model instead.

As far as we know, no one else ships two consumer apps that share a single on-device model this way.

What it means for you

No account, and your data stays on your phone

  • No account. Nothing to sign up for and no password.
  • Works offline. Logging, the measurement and the AI features work in airplane mode. Importing a recipe and searching the food databases need a connection.
  • Free. No subscription. Burnin shows one banner, on its profile tab.
  • Stored on your phone. Your food log, weight, recipes and photos are kept on the device. Bein has no server that holds a copy.

What does go online: anonymous product analytics (screen names and counts, never content or an identity), food database lookups, recipe pages you import, the one-time model download, Burnin's banner ad, and on some Android phones Cookin's voice dictation, which uses Google's speech recogniser. Details are in each app's privacy policy.
