About

OTN

Read full description

OTN applies the mental model of a one-time password to your notes. Every note is born with a lifetime — 10 minutes, an hour, a day, a week — and quietly disappears when its time runs out. Most notes are one-time information: where you parked, a wifi password, today's to-do. They don't deserve permanent storage. OTN is built for exactly this — write it in five seconds, let it go, and never watch your list pile up again. WATCH IT FADE Notes visually age as their time runs out, dimming and blurring until they dissolve. The list itself is the timer. KEEP ONLY WHAT MATTERS Tap a note to Keep it forever, or Release it now. Keeping is a deliberate act, not the default. NOTHING IS LOST BY ACCIDENT Expired and released notes rest unseen in the Archive for a while — then they're gone for good. Restore anything before it vanishes. DESIGNED TO DISAPPEAR A dark, minimal, single-screen interface. No folders, no tabs, no clutter. Choose from three typefaces to make it yours. OTN PRO A single one-time purchase removes ads on iPhone and syncs your notes between iPhone and Mac via iCloud. Nothing piles up. As it should be.

Verdict

The call

The clearest difference is in-app purchases: eeva at none against OTN's 1. eeva also leads on ads (none vs shown). OTN's advantage is update cadence (every 3 days vs every 8 days) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
