Default [Q] Ascend Mate 2 owners?

I am interested in the Ascend Mate 2 but in order for me to purchase one, I need to know if a certain call recording app works on the phone. The app is "Call Recorder - ACR" found here:

Can someone install it from the Playstore and verify if this app works without any issue? Thanks
