About this app

You can write your diary with peace of mind only when it is in a place where no one can see it.

Appiso Diary is a diary focused solely on recording your day, without registration, ads, or servers.

Your diary is stored only on this phone, and if you set a password, the entire entry is encrypted.

■ One entry per day, one diary per date

· Press the [Today's Diary] button in the bottom right corner to open today's entry immediately.

· If you open the same date again, you can continue editing the entry you were writing without creating a new one.

· When you are finished, press [Done]; it will be saved automatically even if you exit via the back button.

· If you delete all the content, that day's entry will disappear.

■ The entire diary is encrypted if you set a password

· If you set a password in the options, a lock screen will appear every time you open the app.

· The saving method itself changes — the diary content is encrypted using a key generated from the password,

so if you do not know the password, no text will appear even if you look at the saved file.

· Even if you change phones and restore the backup, it will not open without the password.

· Since we do not have a server, we cannot find your password for you. Please be sure to remember it. ■ Unlock Conveniently with Fingerprint or Face Recognition

· If your phone supports fingerprint or face recognition, you don't have to enter a password every time.

· Your fingerprint is a secondary key that works only within this phone; the real key is your password.

Therefore, a password is required when unlocking a new phone for the first time.

· The screen locks again after you return from another app, and you can resume writing with a single fingerprint scan.

■ Browse via List and Calendar

· In the [List] tab, recent entries appear at the top. Tapping it opens the entry for that day.

· In the [Calendar] tab, a dot appears on the days you wrote an entry, allowing you to see at a glance how consistently you have written.

· Tapping a past date on the calendar allows you to write a new entry for that day or reread it.

■ If You Selected the Wrong Date

· You can move to a different date by tapping the date at the very top.

· It does not move to dates that have not yet arrived or dates that already have entries —

We have ensured that you will not lose entries by overwriting previously written ones.

■ No Server

· All entries are stored only within your mobile phone. There is no sign-up or login required.

· There are no ads or tracking SDKs, and all features work perfectly even without an internet connection.

· If you enable Android automatic backup, your diary is saved to your Google account backup, so your diary will remain intact even if you change phones.

If you have set a password, the backup is also saved in an encrypted state.

■ Eye-friendly screen

· You can choose between a light theme and a dark theme. You can also choose to follow your phone's settings.

· Dates and days of the week are displayed in Korean, and the calendar starts on Sunday.

■ Recommended for:

· Those who do not want to log in to a diary app

· Those who want to write a diary with peace of mind, even on a phone shared by family

· Those who value writing consistently over fancy decorations
