Defer is the app to get things out of your head. It's a task inbox or a capture inbox. Simply open the app, type (or paste!), and move on, knowing the thing will be there when you need it later. It works best with the accompanying Mac app: capture something on your phone, act on it when you're back at your Mac. - Private by Design: All your data is either stored on device or in a private iCloud container if you've got an Apple ID. - Simple: No bloat. Fast. Just write! - Synced Automatically: No account creation needed. If you're signed in with the same Apple ID on multiple iOS devices, everything will just sync. - Export anytime: Take your data with you in the form of a very compatible .csv file. - Integrated with Siri, Shortcuts, and Widgets (activate Siri and then say "Defer Something") - Add dates, or don't! Put stuff out of site / out of mind until you need it. - Pro feature: Make the app your own by customizing colors and fonts. - Pro feature: Export to Apple Reminders or JSON - Pro feature: Use webhooks to send tasks to other apps, on demand or automatically. We take privacy seriously. Really. We don't track anything about you or how you use Defer.

OTN
Read full descriptionHide 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 clearest difference is ads: Defer at none against OTN's shown. OTN's advantage is update cadence (every 3 days vs every 2 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
