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. :)

Feels like false advertising. the few you have are okay but it feels like a constant cash grab. five base generators, $0.99 at LEAST for a single generator on top of the five, nearly $30 for all the generators unlocked. shouldn't be a free app, or at least shouldn't claim to have 'a ton of generators' when only five are free.

As a DM for many different ttrpg games, this provides countless options for building many different campaigns. I love the simplicity, and overall feel of the app. It's not too complex, and I appreciate that I'm not bombarded by endless ads enticing me to buy stuff. Are there paid options within this app? Yes. Do I get to choose which ones I want based on clarity? Also yes. Will I purchase the some of these add-ons? Also yes.
