Yemma 4 is an AI chat app that runs entirely on your iPhone. Your conversations never leave your phone — not even for a moment. And it's completely free.
Chat with Google's latest Gemma 4 model entirely on your device. No provider connection, no cloud relay, and no account required.
You can. It's great. But every message you send passes through someone else's servers, gets stored, and can be used to train future models. Yemma 4 works differently.
You shouldn't need to wonder who's reading your chats. With Yemma 4, there's nowhere for your data to go — everything runs on your phone, period.
Download the AI model once, then use it anywhere — on a plane, in the middle of nowhere, or just with Wi-Fi turned off. It's always ready.
Cloud AI services slow down when everyone's using them. Yemma 4 runs on your phone's hardware, so responses start immediately — every time.
No account, no subscription. Open the app, grab the model, start chatting.
Ask follow-ups, change your mind, think out loud. It keeps up.
App and model are both open source. Read every line on GitHub.
