About

Sensory Switch Flip

Features
Read full description

Switch Flip is a switch enabled classic style fun activity, to help develop assistive switch or alternative device usage – and also enjoy a trampolining challenge. Switch Flip has modes to support a learner developing access switch use. Since iOS14 the Microsoft Adaptive Controller (and XBox Controller) are fully supported by iOS devices, so we are adapting our range of apps to work with the impressive access device. Switch Flip also responds to screen tap, mouse pointer device as well as external keyboard control (space, enter, 1, 2). Flipping starts on keypress down and stops on keypress up, so if you have an access switch that works on key press down and up, then Flip can be controlled well with that device. Any queries please contact us at support@sensoryapphouse.com. There is a live demo on the app website link. The trampolining has a detailed scoreboard, counting the amount of single/double/triple flips, and the heights achieved when bouncing. The score can be reset from the settings panel. The settings panel allows the switch input to be changed between a "Tap" mode and a "Press/Hold" mode which can be helpful for a user. You can also mute the sounds and change the flipping speed to up the challenge. This game could be used by two people controlling the bouncer. Sensory Switch Flip contains no adverts, does not require a subscription and does not collect data.
