Slide Remote is a free Android application that allows you to remotely control your presentations. You can download the app and the Windows app from the developer's website. With Slide Remote, you can control any presentation software you want, including Prezi, Microsoft PowerPoint, Slideshare, and many more.

One of the best features of Slide Remote is the QR code sync, which allows you to start using the app in less than two seconds. You can also use the laser pointer and jump to specific slides with ease. Additionally, the app supports multiple controllers, making it easy for team members to control a presentation.

Another great thing about Slide Remote is that it doesn't require registration and doesn't have any ads. The Windows app is plug and play, and the app has unlimited usage with high performance. It also works with proxies without any additional effort. The native material design interface looks pretty great as well.

Please note that Slide Remote 2 has been released, and it is recommended to download that version instead of this one. This app will soon be removed from the Play Store in favor of Slide Remote 2, so be sure to update soon!
