Clear Touch Collage™ is a powerful, yet easy-to-use, application that lets you share up to four devices directly to your Clear Touch™ panel. It enables you to encourage interaction and involvement, even in a classroom setting where each student has his or her own device. Helpful permission controls give you the ability to manage who is able to connect, ensuring you have the necessary control for keeping everything organized and running smoothly. Collage is especially useful for show-and-tell and student presentations, but it is equally useful in enabling teachers to teach cooperatively. For example, in a lab setting one teacher could moderate the presentation from his or her laptop, while another teacher or teacher’s assistant could demonstrate an experiment on a camera-enabled device. A teacher could even connect multiple devices in the classroom and then move easily from device to device without having to constantly disconnect and reconnect. The true genius of Collage is that it is a highly compatible solution that works seamlessly with nearly all of today’s most popular devices, including iPhones and iPads. On top of that, connecting to Collage is remarkably easy to do. Simply enable Collage on your Clear Touch™ panel, enter the displayed access code, and you’re ready to go!

ReceptionRating · Positive reviews · Number of ratings

Clear Touch Collage holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Clear Touch Collage has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Sphere2's written reviews are positive against 60% of Clear Touch Collage's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sphere2 ships an update every 2 months, Clear Touch Collage every 4 months. The most recent releases landed on June 11, 2026 and September 17, 2026 respectively.
