Right? I felt like it was some kind of trick to at least get your email before showing you the app actually is a subscription only app.

100% this. I don't really care about the whole bubble thing. I just though oh cool, let me try this and find some iphone user to see if it works. Downloaded, auth'd my google account which was the only option which is not right either... and then bam, paywall. Yes it does say it costs $1.99/mo almost at the bottom of the linked page, but I 100% would not have downloaded this if I knew that up front. And absolutely would not have auth'd my google account.

There 100% should be a message BEFORE logging in that has the pricing. And allow for actual email signups too, not google or any other 3rd party logins.
