I tried them. Integrating their SDK is a breeze. 30 minutes and you're ready to go. I also signed up for their paid analytics package. It's OK - nothing revolutionary but enough to track events.
A few weeks later I wanted to cancel the subscription (app development would take a little longer). But there's no button to cancel. So I wrote them an email and all I got was a reply where they'd like to give me a Skype call to "talk over my decision".
That and their regular "customer engagement" emails (I just want to use your service, I don't want to video chat every weekend) made me choose Devmate instead.
(I still pay the $10/month for the analytics so I guess their plan worked).
Surprisingly good. They don't support anything out of the box but they always seem to have a workaround (for instance I am switching to a "nag" demo model instead of a time based one i.e. like Sublime)
Stuff like that is not natively supported by Paddle but it will be and there are ways to do it through their framework.
And as long as I price my app at around $10 or more it's cheaper than MAS.
I am writing a "year in review" post about Ghostnote where I am going to spill all the beans :)
