We don’t use ads or sell user data. Subscriptions support the infrastructure needed to maintain the app (belive or not, Microsoft, Google, and Amazon all want money for some reason). We understand that it might be expensive. You can try it free for 30 days to see if it’s right for you. Also, we are indie devs who need to eat and pay rent. Unfortunately, ad-supported monetization only works for the mass-appeal apps, whereas Vocaber is niche. We don’t have any investment capital either. Theoretically, we could cut some corners and reduce quality of some features to make the app free for the users who don’t care, but it isn’t planned at this point.
