I started voice-journaling because I couldn't sleep. Then I rebuilt the app around it to run entirely on-device.

I moved to a different country earlier this year for my studies. Somewhere around then I started having nights where my head wouldn't stop, one
thought leading to the next, lying there for hours. Not every night. Maybe
once every couple of weeks at first, then more often.

I'd never journaled in my life. Tried typing it out at a laptop for a few
days — lasted three, because I kept editing myself into the version of the
day I wanted to remember, not the one I actually had. Switched to just
talking into my phone before bed instead. That one stuck. Two and a half
months in, I've made 37 entries across 75 days. Skipped almost half the
days and it didn't matter — voice doesn't let me self-edit the way typing
did, and that's the whole reason it works.

I built Weave to make that habit easier to keep. First version was a cloud
AI web app — worked fine, until I actually sat with what that meant: every
one of those 2am entries was going out to a model provider I didn't own.
That's not a small thing to hand over. So I've spent the last few weeks
rebuilding the entire reflection pipeline to run on the phone itself.

Stack: Llama 3.2 3B (Q4_K_M) via llama.rn, Whisper small.en via whisper.rn
for transcription, MiniLM for semantic embeddings — all local, SQLite,
nothing synced anywhere. Metal on iOS, CPU on Android. Works fully in
airplane mode after the one-time model download.

Numbers from device testing: iPhone 17 goes save-tap to a complete
reflection in ~11.6s. OnePlus 9R on CPU is ~59s — still working on that
gap. Reflection quality on a 3B model isn't going to out-nuance GPT-4, and
older phones sit right at the memory edge. Wanted to say that upfront
rather than have someone find it themselves.

iOS TestFlight is open: testflight.apple.com/join/wpPKnRXg — if the "talk
for two minutes before bed" habit sounds like yours, I'd love for you to
try it and tell me what's broken.
