It is pricey for being an Android app but for sure cheaper than Push...
To read he whole review go here:
Here is the stolen summary...
+ No in-app purchase needed to control Live devices
+ Split-screen view
+ Smooth and fast to get around
+ Wi-Fi or cable connection
– No cheap upgrade from previous version
– You might miss pots and faders
touchAble Pro is the best app controller for Live, and a solid rival for Ableton’s Push – each has its unique advantages. Not cheap, as apps go, but a bargain for what it does. Absolutely recommended.
