Never clean up notes again. Bubble Note turns note-taking into texting. Jot a thought, send it like a message, and it quietly deletes itself when its time is up — so you never waste a second tidying done notes again. Like a bubble, every note simply pops and floats away the moment it expires. That's how Bubble Note got its name. WHY YOU'LL LOVE IT • Auto-deleting notes — every note expires on its own schedule, zero cleanup • Chat-style capture — writing a note feels like sending a text • Time-based "friends" — organize by how long a note matters, not by folders • Photos & screenshots — attach images in one tap, view them full screen • Mark as done, forward, edit or delete — all inline, no clutter • 30-day Trash — recover anything you deleted or that expired CHOOSE A LIFESPAN • Forever — keep it permanently • 1 Month — disappears 30 days after you send it • 1 Week — disappears 7 days after you send it • This Month — clears at the end of the calendar month • This Week — clears at the end of the calendar week • Today — gone at midnight tonight Create your own custom friends with any lifespan, color and icon. PRIVATE BY DESIGN • No account, ever — just open and write • Works 100% offline — no internet needed • Your notes never leave your phone — nothing is uploaded, synced, or shared PERFECT FOR • Daily to-do lists that clear themselves out • Quick reminders you only need for a few hours or days • Screenshots and links you'll act on soon and forget later • Temporary thoughts you don't want cluttering a permanent notebook Capture it fast. Forget about it. Let your notes clean up after themselves.
