This one feels good because both the Ad revenue and In-app purchases are increasing steadily.
Of course my cost is also increasing but I'm tracking the profit/loss and it looks like if the growth continues I can make this into a passive profit generating stable project!
Now that Ad revenue is 150% month of month, in-app purchases really picked up and increasing similarly.
Only problem is my churn, unfortunately people install the app and realize later they have to watch some ads to send a text and uninstall right away. And some really "mean" reviews. But oh well, it comes with providing a service for people...
