Make a simple app for a simple life. The first project from the Charles App. www.charlesnote.net Simplified the features as much as possible by taking out all the unnecessary ones, based on my experience of using memo apps for the past 10 years. "It is only finished when you can no longer make it any simpler." That was what I had in mind and I really did make it as simple as possible. I took out the features that I don't use and even steps that are not needed, and I'm finally satisfied with it. I will update the features that may be needed later. All the features are located at the bottom, so keep your grip on the phone as you use the app. Features ㅇ Web service launch [www.charlesnote.net] ㅇ Use charles note in iphone, ipad and web ㅇ Notepad name settings ㅇ Slide down to create a note ㅇ Touch the content to edit a note ㅇ Slide to the side to search ㅇ Slide to the side to change settings ㅇ Delete memo ㅇ Delete note ㅇ Copy memo ㅇ Delete multiple selections ㅇ Note favorites ㅇ Adjust font size ㅇ Select among 20 different themes ㅇ Export note ㅇ Share note ㅇ Sign up, login
