Wifi Hotspot Widget is a free app available for Android devices that allows users to share their mobile internet with other devices with just one click. The app is easy to use and comes with no advertising. Owners of devices with Android Oreo and above who make a donation have the chance to get a notification shortcut that changes color depending on the hotspot state (enabled/green, disabled/red). However, the developer does not guarantee that the notification will work on every device. It's important to note that the donation is only for supporting the developer and not for the possible notification.

The app is a great utility tool for those who frequently share their mobile internet with other devices. The one-click feature makes it easy to use, and the absence of ads makes the user experience more enjoyable. The app also provides an added benefit for those who donate and own devices with Android Oreo and above, as they can receive a notification shortcut that changes color depending on the hotspot state. Overall, Wifi Hotspot Widget is a reliable and efficient app for sharing mobile internet with other devices.
