Is your test version available on the Google play?
the beta testing version is not launched yet. but you can try the demo apps on their website.
yes i already try their demo apps and it works perfectly for me.
I have tried the demo app and there are still work to be done, but i think is working great. I suggest they should let medical professionals to try their app to further improve its use.
yes there some improvements that needs to be done, i think hearthy also see that but thats not bad for a demo apps.
