Dev is a scam artist- avoid
The app should be labelled with in app purchases not free. Just like his other apps, scams.
Response from developer
Thanks for your feedback, Codowlsky Polopumus! On the app page in the "appstore" there is information that the app includes purchases, I'm very sorry you didn't notice. Also, the application has free scenes and functions available in full access, which are enough to understand the functionality of the application. We will try to add more free features and scenes for you in the future!
