Some notes are worth a folder and a title. Most are not. JKST Note is for the other kind — the thought, the todo, the expense, the password you just made up — captured in seconds and then left alone.
Tap the plus, pick a type, type, save. No folder to choose, no title to invent, no screen to navigate afterwards. The loop is capture and done.
CAPTURE WITHOUT A DETOUR
Start a new note from Control Center, the Lock Screen, or the Action button. Or say "Jot this in JKST Note" to Siri; five spoken shortcuts open the same capture form. Use the share sheet to send a webpage, selected text, or image into JKST Note. Attach a photo from your library or take one with the camera, or record audio for an on-device transcript.
NOTES WITH A SHAPE
A note here is a small typed card rather than a blank page. Seven types come built in — Jot, Todo, Log, Account, Expense, Contact, Link — each with its own fields, and Todo items tick off as a checklist. Invent your own types on your iPhone or Mac: add a field, choose its kind, mark it required, prefilled, or secret. Editing a type never rewrites the notes you already captured.
SECRETS THAT STAY SECRET
Mark a field secret and its value is encrypted on your iPhone, shown as dots, and left out of search. Revealing it or copying it takes a fresh Face ID check (or your passcode) every single time, however recently you unlocked the app. A revealed value re-hides after ten seconds. A copied one clears itself from the clipboard, and never travels to your Mac or iPad.
Write down the six-word recovery code and a lost phone does not mean lost secrets. It is also how a new iPhone or Mac opens your secrets: until you enter it there, they stay locked on that device. The app tells you that plainly instead of burying it.
PRIVATE BY DESIGN
No account to create, no analytics, and no server of ours. iCloud Sync is optional and asks first. With it on, your notes go to your own private iCloud, which we cannot open; secret fields stay end-to-end encrypted with a key only your devices hold, and everything else uses Apple's iCloud encryption, which is end-to-end too if you turn on Advanced Data Protection. With it off, the app makes no network requests at all. The app locks behind Face ID, and the app switcher shows a cover instead of your notes.
FIND IT LATER
One reverse-chronological stream, filter chips per type, and full-text search across everything you captured — except your secret values, which are never indexed. Deleted notes wait thirty days in Recently Deleted before they go.
ON YOUR MAC TOO
The same notes in a native Mac app, with Quick Capture from any app on a keyboard shortcut. Turn on iCloud Sync on both to keep them in step. One purchase covers JKST Note on iPhone and Mac.
THE NAME
Jot, Keep, Search, Trust. Also Jot, Keep, Secure, Type. Between them they name the five things this app is about, which is more than four letters usually manage. And, simply: Just keep stuff together.
Requires iOS 18 or later on iPhone. The Mac app requires macOS 15 or later. There is no iPad version.
