An app that will transform your phone into a back massager.
Back Massager
This app can transform your phone/tablet into a back massager*. It's really easy to use, just select one of the two modes from the main screen(back massager or shoulder massager mode**) and press your device against the area that you want to massage.
*For this app to work your device must actually have a vibration function. Keep in mind that the strength of the vibration(and quality of the back massage) will differ depending on the device you're using.
**Right now there's only back massager and shoulder massager modes but we'll be adding new modes in the future.
