I tried them. Integrating their SDK is a breeze. 30 minutes and you&#x27;re ready to go. I also signed up for their paid analytics package. It&#x27;s OK - nothing revolutionary but enough to track events.<p>A few weeks later I wanted to cancel the subscription (app development would take a little longer). But there&#x27;s no button to cancel. So I wrote them an email and all I got was a reply where they&#x27;d like to give me a Skype call to &quot;talk over my decision&quot;.<p>That and their regular &quot;customer engagement&quot; emails (I just want to use your service, I don&#x27;t want to video chat every weekend) made me choose Devmate instead.<p>(I still pay the $10&#x2F;month for the analytics so I guess their plan worked).
