Yozzi User Guide

Based on app v1.1.17+26 · Guide updated 2026-10-07 · Deployed app now Checking…

In short: Yozzi keeps your memos (jotted down like a chat) and your to-dos (checklists) in one place. Everything is stored only on your device, and Google Drive sync is an optional feature you turn on only if you want it.
Note: The screenshots in this guide show the Korean interface. The screens are the same in English and Japanese — only the text differs.

1. Getting started

You can start right away — no sign-up or login. The app has three main areas.

The tabs sit at the bottom of the screen on a phone, and on the left when the screen is wide. On a wide enough screen, the list and its contents appear side by side. The magnifier at the top right is Search, and the gear is Settings.

If you are new 1.1.17+ — On first launch you get a Getting started list and two memo pads, Writing memos and Organize & find, so you can learn by tapping around (you can replay them from Try it yourself in Settings). Hidden gestures such as long-press and drag are explained once by an on-screen screen tip the first time you open each screen. Turn them off with Don't show again, and bring them back with Show screen tips again in Settings.

Install: on the web, use Settings > About > Install as an app to open it like an app without the address bar. On Android, get it from Google Play.

2. Memo pads

The memo pad list on the left, and an open memo pad called 'Ideas' on the right with a short memo, a collapsed long memo and a photo memo stacked as bubbles
The memo pad list is on the left and an open memo pad is on the right. Long text is collapsed with a Show all button, and photos are shown inline. (Screenshot shown in Korean.)

Create and write

  1. On the Memo tab, tap +, name the pad, and tap Create.
  2. Open the memo pad and type in the box at the bottom. Press Enter to send and Shift+Enter for a new line. On a phone's on-screen keyboard, Enter inserts a new line, and the up-arrow button on the right sends.

Uncheck all 1.1.17+ — for lists you reuse, like groceries or packing lists, tap Uncheck all in the Completed section header to reset them at once. When you check the last item, an All done prompt appears briefly so you can tap it right there. Both have Undo. It appears only when the filter is All.

Swipe to complete is off by default to prevent accidental completion. Turn it on under Settings > Gestures and you can swipe an item sideways to complete it. Swipe between lists Next update — on a list or memo pad screen, swipe left or right to move to the neighboring one (on by default; turn it off in the same Gestures section). When swipe to complete is on, completing takes priority on top of an item. After you move, a small marker at the top briefly shows which list you are on. The timer icon at the top right of a list is a Pomodoro timer for focus and break time.

4. Search

The part matching your query is highlighted. (Screenshot shown in Korean.)

The magnifier at the top right (Ctrl+F) searches memo pads, memos, lists and to-do items at once. Enter several words separated by spaces to find only items containing all of them. Korean initial consonants (for example ㅋㅍ) also work. Spacing differences, related words and compound words are matched too (for example 차사고 finds 자동차 사고). Korean only. Use the chip at the top to gather your Favorites.

FAQ

Where are my memos stored?

Only inside this device (or this browser). If you uninstall the app or clear the browser's site data, they disappear with it, so protect important content with a backup file or Drive sync. On Android, if the device's Google automatic backup is on, they may also be restored on a new device.

Can I get back a memo or to-do I deleted?

Only with the Undo that appears briefly at the bottom right after deleting. After that, you need to restore from a backup file or a Drive backup.

My locked memo pad won't open.

The lock opens with your device's screen lock, such as a fingerprint, PIN or pattern. If the device has none, you will see a notice — turn on a screen lock in your device settings first.

The web and app versions are different.

While Google Play is reviewing an update, it is normal for the web and the app to have different versions. New features appear first on the side where that version is released. Check the version under Settings > About.

This page looks different from the app.

Compare the Based on app version at the top with the Deployed app version. If they differ, the screens may look slightly different.
