Price issue

This app was in AppsGoneFree on June 2, 2019. The download was free, and the upgrade was supposed to be free, but I got charged for the upgrade. Not crying over the $2.15, but still not happy about being charged for something that was supposed to be free.

Developer Response ,

The free app promotion ended this morning 5/3 EST. The advanced features (in-app offer) were not part of the promotion. You can always ask for refund on any charges on the AppStore using Apple’s official refund procedures :-)

Bait and switch?

I downloaded this app as it was featured on appsgonefree this morning. When I downloaded the app, it’s asking for money to add the very features advertised for free.
I don’t have an issue with paying for a well made app like this, but something isn’t right with the pricing or someone got their wires crossed.

Developer Response ,

The app is free for a limited time during the president’s day weekend - however the in-app purchase to add conversions and basic graphing is additional functionality that requires purchasing. Hope this helps explain why when you try to convert it will ask to purchase - all other features are w/o pop ups.
