Almanac: Voice‑first outdoor journal for zero‑signal walks

Description and use

Almanac lets users quickly record outdoor observations via voice, works offline, keeps data local and encrypted, and reduces screen time to under five seconds.

Problem

Journaling outdoors is hard because it requires screen time, battery drain, and cellular connectivity, making it impractical for hikers and evening walkers.

Outcome

Almanac reduces screen time to <5 s, works offline, preserves battery, and keeps notes private, enabling hikers to record observations quickly and reliably.

Workflow

• Download the Almanac app and lightweight open models (Gemma 3 1B LiteRT on Android or Whisper in the browser).
• On the trail, tap once, speak what you saw, and tap save.
• The phone returns to pocket; screen stays on for <5 s.
• Notes are stored locally (IndexedDB on web, Room on Android) and encrypted with AES‑256‑GCM if backed up.
• When reconnected, the app uses Gemma 4 on Cloudflare Workers AI to map speech to consistent entities and answer queries.
• The app nudges users with seasonal predictions from TabPFN‑3.5.
• Optional end‑to‑end encrypted backup sync via a 24‑word recovery phrase.

Evidence

Writing after a long day feels like homework. And three months later, I can never remember when any of those moments actually happened.
