Electra is a simple, straightforward stimulating app for people with special/complex needs of all ages. It is visually stimulating and suitable for a range of abilities. Electra responds to taps and up to 3 finger simultaneous touch movements. Tap to change effect. Touch with 1, 2 or 3 fingers to (simulate) shock! You can also create neat lightning effects for screen capture.
This app is best used on a phone in landscape mode. If you would like to lock the app on the phone to be landscape, you could use the Android Accessibility Interaction Control. Go to Settings/Accessibility/InteractionDexterity/ and turn on interaction control. Once the phone is running Electra and in landscape display, Press and Hold the Power Key and the Volume Up key for 2 seconds to activate the interaction control. There are some options within interaction control to also block out areas of your screen such as the Navigation Bar.
