Just focus on your ASO, There is a market for these kinda apps!
I tried to focus to different audience and I enhanced the caling and sms functions ....
I use the app in my daily life ...I hate speaking to assistents, that is why I do not have conversation modules and just some basic stuffs
I belive in using app without answering to a robot each time you want to make a call
I tried to localize as well recently I found out that a video testimonials bring 7 more downloads a day from Brazil while France does not seems to like video testimonial from a foreign french speaking person
