I cannot restore my purchase and is not pleased with this. It doesn't matter how much I try it just is "Stuck" and when I go to tap to go buy, it tells me that I already own it. I love the app, but it's very frustrating to experience this! Also, it's very difficult for me to read more than half the time as I have Irlen's Syndrome. Dark mode is my friend in such a case. Will not consider a subscription if these problems are going to be present.

edit: Thank you for the help, sent an email with follow-up 4/23 This is a great tool and I'm enjoying using it, Characterize, and DungeonRoller app for Worldbuilding. I really like the content generators included. However my only problem is the Share Option is broken. Everytime I select the share icon, the app crashes out. My phone says there is a bug and to clear caches, but that doesn’t solve the problem.

I really do like this app. Too bad it's not affordable. All the individual pricing on it is extremely disappointing. You should really have an option to purchase it all for a single price or even pay by the month/year. The way it's priced now is ridiculous, in my opinion. I'd love to have access to what you have but not enough to put myself in debt. Rated 2 stars bc I like the app options. Otherwise, I would've rated lower.

Hey, thanks for the review. We have some generators that require money to use, it's true, but there are literally quintillions of characters that can be generated without spending any money at all. I'm an indie dev trying to make a living so having things for purchase is necessary, but it was important to me that everyone could use the app. :)
