Notes that stay on your iPhone. Write them, sketch them, lock them behind Face ID, and put them on your Home Screen. No account, no cloud, no ads, no in-app purchases and nothing to subscribe to. WRITE IT, OR DRAW IT Type a note, or sketch one with pen, marker and pencil — Apple Pencil or your finger, with adjustable width and color. Start a drawing over a photo from your library or straight from the camera. Undo and redo sit under the keyboard while you write. Check items off inside the text: a checklist line is part of the note rather than a separate list, and the box responds wherever you tap it. EVERYTHING WHERE YOU LEFT IT • Pin the notes that matter to the top • Color-code them, tag them, and filter by a tag in one tap • Search titles, bodies and tags at once • Compact, standard or detailed rows, remembered between launches • Deleted notes wait 30 days in the trash, and can be opened before you decide • On iPad the list and the note sit side by side, through rotation and Split View alike REMINDERS THAT ARRIVE Set a date and time on any note and it comes back as a notification — as a banner even when the app is already open, and tapping it opens that note rather than the list. If iOS will not schedule it, the app says so instead of losing it quietly. Notes with reminders also line up in a calendar view, by the day they are due. NOTES THAT REMEMBER WHERE THEY WERE A note keeps the place it was written, and the map shows them all — notes made in the same spot share a pin. Useful for a trip, a viewing, a walk around a site, or anywhere the location is half of what you wrote down. LOCKED IS LOCKED • Lock any note behind Face ID or Touch ID • The notes file is unreadable while the device is locked • An unlocked note is covered before iOS takes its app-switcher snapshot • A locked note's reminder reaches the Lock Screen without its title or its text • Search does not look inside a locked note ON YOUR HOME SCREEN AND LOCK SCREEN Small, medium and large Home Screen widgets show your most recent notes, pinned first — and tapping one opens that note, not the list. All three Lock Screen shapes are there too: the newest note as a line, as a title with a line of text, or just how many notes there are. A locked note shows its padlock and nothing else, in every size. Ask Siri to create a note, or put it in a Shortcut. BUILT FOR EVERYONE Every icon-only control is labeled for VoiceOver, and a note's row is announced as one thing rather than as the seven pieces it is drawn from. A checklist line says whether it is checked. Text follows your Dynamic Type size, including the checkbox and the area you tap to check it. The unlock button shows the method your device actually offers. YOURS, AND ONLY YOURS • No ads • No in-app purchases, no subscription • No account, no sign-in, no cloud, no data collected • Works completely offline • Back up and restore everything as a single file • English and Czech • iPhone and iPad Just your notes. Nothing else.

Verdict

The call

The clearest difference is review sentiment: J at 100% against Notes Writer's 45%. J also leads on rating (5.0 vs 4.5) and in-app purchases (none vs 8). Notes Writer's advantage is ratings volume (7.3K vs 1) and update cadence (weekly vs fortnightly). On price, ads and device support there is nothing between them.
