About this app
Since the iPhone was born, there have been tons of note-taking apps. Evernote, OneNote, Notion, Craft are awesome. The iPhone's default memo application is also beautiful. But there’s still missing! As note-taking apps have become heavier, we need a simple and tiny secondary memo app for short memo. Penna is super small app to keep short text memo quickly. Use Penna to write some key words that suddenly hit your brain! Never forget your ideas! You don’t have to be paused a moment to make or edit note pads anymore. All you need to do with Penna is just to type short text as fast as you can!
