SimpleMemo is a free utility and tool app developed by SKYSENSE Inc. for Android users. As the name suggests, it is a simple and lightweight memo app that allows users to take down notes easily.

The app offers basic memo functionalities such as adding, changing, copying, and deleting memos. Users can also input their memos by voice if they find text entry difficult. Sorting memos is also possible by simply dragging and checking the "Sort" checkbox.

To view detailed information about a memo, users can tap on it, while a long tap will display the context menu. The app also saves the sorting state after sorting, so users don't have to worry about losing their sorted memos.

The app's future plans include adding a grouping feature for memos, a widget feature, and a setting screen. The latest version of the app, 1.0.18, includes a "Make your original color" feature with a color picker, a new text size "Huge," and the ability to switch between full-text and abbreviated-text display styles.

Overall, SimpleMemo is a great app for users who want a no-frills memo app that is easy to use and doesn't take up too much space on their device.
