OneNote is a comprehensive digital notepad that was developed by Microsoft Corporation. This app includes a highlighting option and a wide range of formatting tools. You can place the OneNote widget on your phone's screen to quickly access content without opening the app. The search function lets you find any type of content that the app generated, including notes and drawings. On devices that have a touch screen, OneNote can be used to create drawings and to convert hand-written notes into typed text. OneNote syncs content across your devices. The OneNote app is compatible with Android versions 4.0 and higher.
