"The only thing you need to remember, disappears neatly in 3 taps." Samsepan is a minimalist Lock Screen sticky note app that strips away all complex features and focuses entirely on 'simplicity'. A sudden idea, a verification code you need just for a moment, or a carton of milk to buy today. Don't bother opening an app to delete these highly volatile, temporary notes. Pin your note directly to the Lock Screen (Live Activity). When you're done, simply tap the widget. Tap exactly 3 times (The Rule of 3), and it vanishes from your screen instantly and conveniently. [Core Features] Instant Volatile Memo: Delete immediately from the Lock Screen with 3 taps, no app launch required. Minimalist Design: Intuitive, clutter-free yellow sticky note UI. Always in Sight: Pin notes instantly to the Dynamic Island and Lock Screen. [Pro Version Perks] Pin multiple notes at once (Up to 4 multi-posts). 4 vibrant theme colors to suit your taste. Accidentally deleted? Recover up to 10 recent notes from History. Pin it simply, delete it without hesitation.

Verdict
The clearest difference is ads: 3 at none against DNSwitch's shown. 3 also leads on iOS requirement (17.2 vs 26.0). DNSwitch's advantage is update cadence (weekly vs every 6 weeks). On price, in-app purchases and device support there is nothing between them.
