"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.

Verdict
The clearest difference is in-app purchases: Folio at none against 3's 1. Folio also leads on iOS requirement (15.1 vs 17.2). 3's advantage is ads (none vs shown). On price, update cadence and device support there is nothing between them.
