Onyx: Home Workout

This app acts like a virtual trainer. It automatically tracks your exercises and gives you accurate statistics on how you performed. We are now part of the Cure Fit family after being purchased in 2020 and we're constantly adding more and more features to this beloved product.

AnyMote: Smart Remote

This iOS app lets you use your phone to control the smart devices in your home. We have built this app to connect to smart devices and we even designed and manufactured a multidirectional IR blaster that the app would connect through BLE for not-so-smart devices, including TVs, air conditioners, and more.
