DotMemo is as basic as any app can get. The problem, however -- and this crops up a lot in apps developed to take on that "simplicity before functionality" mantle -- is that DotMemo is too simple, at least for most people jotting down notes while on the go.
The idea behind the app is very simple. Open DotMemo and you are greeted with a white screen that says "note here." You tap the white space and can start typing. That's it. There are arrows to move your cursor back and forth on the screen (a nice touch for any text editor) and an option to remove the keyboard from the screen, but there are no other functions. All notes are automatically saved to the app and there are no file saves. It's like having a notebook in your pocket. You can't remove and save it for later. For many people this is perfect. It's a great place to jot down quick notes or take memos for later reference. But for chronic note takers, it is less compelling simply due to the lack of features.
To be fair, DotMemo is free and it loads quite fast, something that a lot of other apps do not. It also works offline and doesn't require wireless syncing, but then again, it doesn't sync between devices - all notes will need to be copied and pasted into another file at some point or transcribed. DotMemo is well executed and the fast loading times are much appreciated, but the sheer lack of features is often confusing - what audience is this app trying to appeal to and how? We can think of many apps in this very niche that offer just enough additional functionality to be a better download than DotMemo, without being function-heavy.
