SIMPLE NOTE.

People who kept a paper notebook for years want the same thing on a phone: write it down in seconds, tick it off, be reminded at the right minute and never lose a page, with or without a connection. Most note apps give them either a blank white box or a workspace with more structure than a shopping list needs.

Every screen keeps the paper metaphor: ruled, squared, plain and legal-pad paper, five paper colours, blue, black and red ink, a pushpin for pinned notes, a highlighter and a red pen for circling, with 24 short desk sounds and haptics matched to each action. Writes go to Firestore's local cache first and sync field by field, so two devices, or two people, editing the same list never overwrite each other. Reminders are scheduled on the device, within iOS's pending-notification limit and Android's exact-alarm rules, and a Cloud Function pushes any reminder a phone has not already shown. Accounts are optional: anonymous notes merge into a Google, Apple or e-mail account later.

Simple Note 1.0 is built and being prepared for the App Store, Google Play and the web: notes and checklists, folders, pinned and archived notes, a 30-day trash, search, a month, week and day calendar with a journal page for each day, one-off and recurring reminders, PIN or biometric lock, notes shared by invite link, version history, home-screen widgets, share-sheet capture and JSON or Markdown export. The free plan holds 50 notes; Simple Note Pro, ready for RevenueCat, lifts the cap and unlocks the lock, recurring reminders and version history.
