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.

About

senkora

Senkora helps you keep track of regular activities — private lessons, sports, arts — for your children and for yourself, all in one place. The Today screen answers one question: what now? You see the day's lessons on a timeline and close out a lesson that has already passed with a single tap. Every lesson can be marked as full, partial, missed or postponed. Planned and actual are kept apart: package credits are used only by the lessons you mark, while the number of lessons planned in the calendar is counted separately. The two numbers never get mixed up. Highlights: - Track lessons and activities per person (your children or yourself) - Timeline view with one-tap marking - Full, partial, missed and postponed records, with makeup dates - Hourly, monthly and package payment models - Prepayment for several months at once, split evenly across the months - Payment and package reminders - Statistics: attendance rate, lesson and payment charts - Planned and actual side by side in the calendar - Apple Watch app and a watch face complication showing the time left - Home Screen widget for marking without opening the app, plus Lock Screen widgets - Siri shortcuts and a Live Activity for the lesson in progress - iCloud backup and family sharing - Light and dark theme, iPhone and iPad Instead of complicated spreadsheets, Senkora gives you a clear daily flow and a calendar you can trust.
