Ichinichi
One note per day. End-to-end encrypted. No signup required.
What it does
A daily journal built on creative constraints. One note per day — no folders, no tags, no decisions. Yesterday's notes become read-only, keeping you present instead of endlessly editing the past. End-to-end encrypted so you can trust it with your most private thoughts — not even we can read them. Runs entirely on your device as a PWA. No internet required. No account required. Open the app, start writing.

Look, every journaling app out there wants you to organize things into folders and tags and templates. I just wanted to write something down every day. So I built this. One note per day. That's the whole deal. - Can't edit yesterday. What's done is done. Keeps you from fussing over old entries instead of writing today's. - Year view with dots showing which days you actually wrote. It's a streak chart. Works better than it should. - No signup required. Opens right up, stores everything locally in your browser. Optional cloud sync if you want it - E2E encrypted with AES-GCM, zero-knowledge,…


- DODailyNote – one-note-per-day app with local-first encryptionJan 2026 · ▲5
Hi HN and Happy New Year! I built DailyNote, a minimalist daily notes app: one note per day, a year-at-a-glance calendar, and local-first storage. The interesting bit is the encryption + sync model: - Notes are always encrypted locally before syncing to Supabase. - A dedicated data key (DEK) encrypts notes; your password only wraps that DEK (KEK). - So when you change your password, it just re-wraps the DEK — no re-encryption of note data. I built the whole project in one day using Claude + Codex with a spec‑driven approach (tight PRD → implementation). It’s React/TypeScript, IndexedDB…
- FDFree developer-first OneNote alternativeSep 2025 · app.janta.dev · ▲22
Hey Everyone, been working on a note-taking app called janta (Just Another Note Taking App) the past few months. You can try it out at app.janta.dev (you will be redirected to app.janta.dev/canvas/temporary, which is the locally-stored whiteboard you can access) I felt limited with OneNote, Excalidraw, and other infinite-canvas style apps, so I built an alternative. You have access to code-editors, Desmos graphs, and rich text editors (SlateJS). This is because the canvas is designed in a way that allows web components to exist on the same layer as pen-strokes, so you can annotate…
- TATomoshibi – A writing app where your words fade by firelightFeb 2026 · tomoshibi.in-hakumei.com · ▲25
I spent ten years trying to write a novel. Every time I sat down, I'd write a sentence, decide it wasn't good enough, and rewrite it. The problem wasn't discipline — it was that I could always see what I'd written and go back to change it. I tried other approaches. Apps that delete your words when you stop typing — they fight fear with fear. That just made me panic. I wanted the opposite: not punishment, but permission. "Tomoshibi" is Japanese for a small light in the dark — just enough to see what's in front of you. You write on a dark screen. Older lines fade, but not when you hit return.…
