New: AI Math Solver (experimental) — photograph handwritten math and solve it, fully on-device.

- Hidden until you reveal it: tap AC 7 times quickly
- Runs offline on Google LiteRT-LM, GPU-accelerated
- Snap a photo or pick one from your gallery
- Several Gemma vision models; background downloads resume if interrupted and can be stopped
- Gated models unlock with a one-tap Hugging Face sign-in

Your photos never leave your device — internet only downloads the model you pick.
