I purchased 2 codes for the app. The review sounded promising. I encountered the following issues.
1. There is no way to change the brand, respectively I did not find where the original information can be changed.
2. The generated calendar gave really good ideas, but the history was not accessible. I.e. after each browser close you have to generate the calendar again, which uses up your credits.
3. After I did the refund my account is still accessible with the credits from the purchase.
Overall the app is very well designed, the price is good but more work needs to be done on the features. I would purchase it again if the bugs are fixed, therefore I give 3 stars.
