This is a dead simple app. Write a note it will save it with the date and time it was made. That is pretty much it. You can edit the content, but not the date, or delete the note. There is no alarm or reminder or anyway to sync it with any other app.
It is compiled against Lollipop (api 22) with a minimum requirement of Jelly Bean (api 17)
It was written to run on my 5" (13cm) phone and will default to your SD card.
