Between “open” and “write,” there is nothing. Byosoku Memo is a zero-friction notepad: the moment it launches, a new note and the keyboard are already there. No hunting for buttons, no flipping pages — the app finally keeps up with “let me jot this down before I forget.” ■ Open = start typing Tap the icon and a blank note with the keyboard appears at once. No splash screen, no confirmation dialog. ■ Auto-save, always There is no save button. Every keystroke is saved instantly. Close an empty note and nothing is left behind — no junk notes. ■ Lock Screen & Home Screen widgets Jump straight from a Lock Screen widget into a new note. The Home Screen widget lists your recent notes; tap one to open it directly. ■ Control Center (iOS 18) Add “New Note” to Control Center and start writing from anywhere with one tap. ■ Smart full-text search Kana, full/half-width and upper/lowercase are all treated alike, with multi-word AND search to find any note fast. ■ Export & share Share a single note, or export your whole list as a text file. All data is stored on your device. No account required. [Pricing] Every feature is available. A banner ad is shown at the bottom of the screen. A one-time “Remove Ads” purchase hides it permanently (no subscription). Privacy policy: https://honki.ai/byosoku-memo/privacy.html
