Most notes apps give you a list. Lists are where things go to be forgotten. CustosNotes keeps the note where you cannot miss it: the top of your screen. Hold the circle, say the thing, let go. Then tap once and that note stays pinned — in the Dynamic Island, on your Lock Screen, in your status bar — until you decide it is done. HOW IT WORKS • Hold the circle and speak. One button, no menus, no cursor to find. • Your phone's own recogniser writes it down, in your language. • Let go and the note lands. It starts switched off; you choose which ones earn a spot up top. WHERE IT STAYS • Dynamic Island — the mark and the time, beside the camera (iPhone 14 Pro and later). • Lock Screen — the whole note, readable without unlocking. • Live Activities & Status Bar — pinned notifications and status updates that stay visible until you dismiss them. REMINDERS, WITHOUT THE CEREMONY Tap the clock, spin the dial, done. It saves as you turn. No date to pick — a time that has already passed means tomorrow — and nothing to confirm. ALSO • Type instead of speaking, for when you cannot talk. • English and Spanish, app and mic together. • Dark mode that follows your phone. • No account, no sign-up, no server. Your notes live on your phone. CustosNotes does one thing. It makes sure you do not forget it and your data does not get out of your device.

Verdict
The clearest difference is update cadence: CustosNotes at every 3 days against Bigdata.com's every 2 weeks. CustosNotes also leads on rating (5.0 vs 4.8). Bigdata.com's advantage is ratings volume (21 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.
