The Simple Hub is simply a device to provide a lower cost way of running Simple Sync – which is now available for OS X and Android platforms. We expect it to be available hopefully this month or shortly thereafter. It will be available at store.simplecontrol.com.
The Harmony Hub is comparable to a Simple Blaster not to the Simple Hub. The Harmony Hub simply outputs infrared and is a pure blaster rather than a flexible device like the Simple Blaster which has 3 discrete IR outputs and can even switch to serial control or relay control with many additional options totally outside the scope of Harmony which is 99% an old-school IR product. The Simple Blaster is also open so it is compatible with many products, and much more easily integrated into scenarios like a cabinet where a single point can't reach every controlled device.

The Simple Hub is a totally different beast – the Simple Sync page goes into what that does:
simplecontrol.com/simple-sync/
For most users, the primary function is synchronization between multiple devices. It also provides triggers (both time based and device feedback based), Remote Access and more. Use of Simple Sync/Hub also provides SmartThings Integration and soon will be the core component for our Amazon Alexa integration.
Thank you.
