OnDevice LLM runs powerful open-source AI models 100% on your iPhone — no internet, no cloud, no account.

Your conversations never leave the device. Every word you type, every reply you get, stays on your phone. There is no server to log it, no company to mine it, no account that can be banned.

## Version history (last 5 releases)

### 1.42 — 2026-08-18

New model: Qwen 3.5 2B.

A generation newer than Qwen 3 at 1.28 GB, so it fits most iPhones. Apache 2.0 licensed and, like everything here, it runs entirely on your device.

Also: models that reason before answering now show a quiet "thinking" indicator while they work, instead of their raw notes.

### 1.41 — 2026-08-12

• Fixed: the app could briefly show the trial-ended screen at launch to customers who had already purchased, before their purchase was confirmed.
• The chat screen now says a model is loading instead of showing an empty state while it opens.

### 1.40 — 2026-08-11

• After your first answer, the chat now offers a next step so you can start a fresh task without losing the current one.

### 1.39 — 2026-08-11

• The chat screen now shows real download progress instead of an empty state, so you can see how long the first model takes.
• You can type your first message while the model is still downloading. It sends by itself the moment the model is ready.

### 1.38 — 2026-08-08

• Fixed: Workspace could stay locked even after subscribing. If you own Lifetime and subscribed to Workspace, it now unlocks correctly.
• Stability improvements.
