Metrik for Samba fee/subscription

I noticed that on Google Play Store description it says that MetriK is free on a 60 day trial. What happens after 60 days? Will there be a charge or subscription?
I can’t find any other info about the cost of it.
I want to include it as a feature for my new customers but not sure if it is a paid feature or not.

Thanks,

Chris

Its still beta testing most reports don’t work yet just the main screen. My best guess is once it’s fully working then it will require the subscription.
