Features
Read full description

SimplNote is a notes app you actually want to scroll through. Notes are cards. Swipe through them like reels, double-tap to favourite, swipe left right to delete one. No folders. No tags. No clutter. Jot, list, share — that's it. • Quick status-style notes for one-line thoughts • Tick-off checklists that glide to the bottom as you go • Eight built-in fonts — handwriting, coding, display, serif • Eight one-tap colour themes for every mood • Favourite the ones worth keeping Made for friends, not feeds. • Pair with a friend by scanning their QR code or sending an invite • Share a note with one tap — they see it instantly in their own reel • Per-recipient avatars and shared favourites Built to feel fast. • Offline-first: every tap saves locally and syncs in the background • Smart 3-second debounce so a flurry of ticks becomes a single sync • Reanimated transitions everywhere — swipes, springs, smooth list reorders • Optimistic UI: no waiting for a server before you see the change Private by design. • Sign in with Google — we only keep your name, email, and avatar. • Note contents are encrypted. • No ads. No tracking. No third-party analytics. Designed to disappear. • Hand-drawn paper-cut sticker icons • Dark-first theme that's easy on the eyes • A first-time tutorial that gets out of the way fast If you've ever wished your notes felt less like a database and more like a feed of your own thoughts — this is for you.
