Hidden Cost

It was not clear that the “free” version has a 100-fic limit. I understand you need to make money, but I spent hours setting up and organizing my library before discovering the limit. I probably would have subscribed had I known from the beginning. The app interface is great. $4 is still too much for what the product does considering how much other apps cost.

Response from developer

Hi there! I'm very sorry to hear it wasn't clear since that wasn't my intention. There is a paragraph in the App Store description that details the free limit, and it's mentioned right at the top of the website's landing page and then explained further down. I'll move the paragraph about the pricing tier higher up in the App Store description so that it's easier to find, and consider other ways I can make it clearer before someone fills their library! I appreciate the feedback on pricing and I definitely want to lower it in the future. The app is still very young and so the price needs to sustain the costs on a smaller user-base. I appreciate that people who want to use the app need to take on that extra cost to help the app get going. Thank you for a thoughtful review and I hope you can come back in the future!
