A handy diary and memo app that I created after being asked by a friend to make it! It's so comfortable to be able to take notes with the same feeling as using your usual SNS app! You can easily take notes with the same sense of tweeting on SNS, and later you can review them on a daily, monthly, or yearly basis. By taking detailed notes and reviewing them later, they can be read as significant diary entries! For viewing the notes, there are three options: ・Timeline format ・Calendar format ・Bulk reading Please feel free to choose the one that suits your lifestyle! We paid special attention to usability during implementation. I would be grateful if it could be of even a little help in your note-taking life. 【Premium Service】 ■ Unlocked Features Removal of in-app advertisements Photo recording Customization of theme backgrounds Passcode lock function ■ Duration It will be automatically renewed one month from the application date.
