About

monomemo Simple Memo

Read full description

monomemo is a memo app that lets you start writing the moment you open it. In fact, by the time the app launches, it already feels like you’re in the middle of typing. The keyboard pops up automatically from the start, so you don’t even need that extra tap on the screen. There is no network connection, only one memo, and saving happens instantly and automatically. The app is designed to be as light and fast as possible, keeping the same smooth experience no matter how long you use it. Even apps often called β€œsimple” usually come with features you’d naturally expect. monomemo has almost none of themβ€”there is truly nothing here except the ability to take notes. The design is so stripped down that you might hesitate to even call it β€œdesign.” But that’s exactly why monomemo feels unique: minimal, stress-free, and unlike anything else. Main Features - Only one memo. No files, no folders, no unnecessary management - Automatic, instant savingβ€”always stored locally on the device (iCloud not supported) - Maximum size: 32 KB (enough for about 10,000 characters) - Absolutely no network communication - No settings for font, size, or color - Light/Dark mode follows the system setting - Widget support (3 sizes) with small text; tapping opens the app - Portrait orientation only - Software keyboard always visible (hidden when an external keyboard is connected) - Supports iPhone with iOS 17 or later
