Simple Memo is a straightforward sticky notes program available on the Android platform. The developer, John M.C.Huang, created it as a favor for his wife, who wanted an uncomplicated and ad-free app to take notes on her phone. The program lives up to its name, providing a simple and easy-to-use interface that allows users to write and save memos quickly.

One of the standout features of Simple Memo is its support for four background colors, allowing users to customize the look of their notes. However, the program doesn't offer any advanced features like reminders or collaboration options. Despite its basic functionality, Simple Memo is a reliable and useful option for anyone looking for a no-frills sticky notes program on their Android device.
