Why do you guys not have a web interface where I can manage the account and pay for plans without buying credits from google play. This could be very useful in a business setting where one might want to provide inbound #s to employees who don't quite justify buying a phone for. One would need a web portal to manage them rather than having to have it touch every phone when a change needs to me made. And there are plenty other reasons to have a web interface for managing accounts and not just the app.
We don't currently have a way for total management of the app on our web app, but we do offer subscriptions outside of the app stores. Here's where you can upgrade to a subscription via our web app: https://www.brnr.me/supportupgrade.
We're looking into expanding the capabilities of the web app, we just haven't settled up what those are going to be yet. Thanks for your patience!
