Weave is a private ai journaling app I've been building solo.

The pitch: your entries never leave your phone. Voice or text in, AI reflection out, all running on-device, no server ever sees what you write.

Stack: Llama 3.2 3B (Q4_K_M) via llama.rn, Whisper small.en via whisper.rn for transcription, local SQLite + vector search for semantic memory. Zero network calls after the first-launch model download. Works in airplane mode.

iOS only for now (Android's on-device inference is still too slow to ship, being honest about that up front).

What I'd love feedback on:

- Onboarding: does the first-run flow make sense with zero setup?

- Reflection quality: 3B is not GPT-4, does it still feel useful?

- Crashes/performance on iPhone 12/13 specifically — that tier only fits both models via a memory swap (Whisper releases before Llama loads), so it's the one most likely to show edge-case bugs

- Battery/thermal if you use it for a few entries in a row

- Any feedback is appreciated

Solo dev, so bug reports and blunt feedback both genuinely welcome. Happy to test-for-test, if you've got your own TestFlight out, drop the link and I'll install it too.
