Google AI Edge Gallery (via) Terrible name, really great app: this is Google’s official app for running their Gemma 4 models (the E2B and E4B sizes, plus some members of the Gemma 3 family) directly on your iPhone.
It works really well. The E2B model is a 2.54GB download and is both fast and genuinely useful.
The app also provides “ask questions about images” and audio transcription (up to 30s) with the two small Gemma 4 models, and has an interesting “skills” demo which demonstrates tool calling against eight different interactive widgets, each implemented as an HTML page (though sadly the source code is not visible): interactive-map, kitchen-adventure, calculate-hash, text-spinner, mood-tracker, mnemonic-password, query-wikipedia, and qr-code.
(That demo did freeze the app when I tried to add a follow-up prompt though.)
This is the first time I’ve seen a local model vendor release an official app for trying out their models on in iPhone. Sadly it’s missing permanent logs – conversations with this app are ephemeral.
