I used this app a lot and about a month ago the voice coaching stopped working. The "helpdesk" always tells me to switch on voice feedback etc etc which is of course already on. No one has been able to resolve the problem. My helpdesk tickets always end with a dismissive message telling me to uninstall & reinstall the app and restart my phone. It doesn't work. I would warn against getting wasting your money on an app which used to be great but now doesn't give voice feedback/ coaching.
