Read full description

Atom Note is a local-first note app for people who don't want every record squeezed into the same template. BUILD YOUR OWN STRUCTURE: - Create a category for anything you want to track. - Add list items inside each category. - Each item holds a title, free-form contents, and an icon you pick. CUSTOMIZE EACH CATEGORY: - Pick a background color. - Choose a font style for the category header. - Choose an icon that matches the topic. ATTACH PHOTOS: - Snap a photo with the camera or pick one from your library. - Up to three photos per item, in the order you add them. - Photos stay attached on every device that opens the same item. ATTACH DOCUMENTS: - Add a txt, doc, docx, or pdf file to any item. - Up to three documents per item. - Open a document with your device's built-in viewer. Everything stays on your device. LOCAL FIRST: - All data lives on your device. - No account, no sign-in, no background syncing. - Export a backup as a single JSON file and restore it on another device — fully offline. LOCAL BACKUP AND RESTORE: - Export every category, item, photo, document, and setting into one file you can save anywhere. - Restore from that file on the same device or another one. - Restoring replaces the current data, so it's a complete bring-over. CLEAN, RESPONSIVE LAYOUT: - Minimal home screen with category cards and item count badges. - Layout adapts to phones and tablets. - Card text and icon contrast adjust automatically to your chosen background. MADE FOR DAILY USE: - English and Simplified Chinese. - Tap targets and text sizes stay readable across devices. Atom Note is built around freedom, clarity, and simple daily use.
