Jotters is a fast, private notes app for writing to yourself like a message. Open the app, type what is in your head, and send it to your own timeline. No title, folder, or setup required. Quick thoughts become TODO, MEMO, and LOG cards so you can review them later without turning notes into a project. Write before it disappears - Capture thoughts in a chat-style timeline - Choose expressive bubbles to match the mood - Keep TODO, MEMO, and LOG cards easy to review - Separate life, work, and projects with categories - Save text and links from other apps with the share sheet Get reminded when it matters - Schedule a TODO for tomorrow, next week, or a specific date - Repeat notes daily, on weekdays, weekly, monthly, or yearly - Create custom day groups for personal routines - Write a note now and let it come back when it matters Keep your words yours - Notes are stored on your device - No account required - No ads and no tracking - Export your notes when you need to keep them outside the app - Readable Markdown copies are kept on your device for review Important note about your data Jotters does not sync to the cloud. Your posts live only on your device. To prepare for a new phone or app deletion, export a backup file (.jottersbackup) from Settings and save it outside the app, such as in Files, iCloud Drive, Google Drive, or another place you control. If you delete the app, the posts stored on your device are lost. Write it down. Send it forward. Keep it yours.
