Roast my iOS app(detailed stats inside)
Hi everyone
I have been working on my app for the last 1 and half months
The app allows you to review flashcards before opening any app. You have to review 5 flashcards before unlock. The app idea found a lot of good feedbacks from learn Russia subreddit(really cool guys). Here is the post: https://www.reddit.com/r/russian/comments/1sgw5v0/i_made_an_app_that_allows_you_to_learn_russian/
But, after the initial boost from the reddit post - now, I have no success in growing my app
Totally I have 179 downloads
In May, I have only 33 downloads from ASO. Also, now I receive around 70-150 impressions per day and 0-5 downloads per day just from the ASO.
BTW, app is translated into 8 languages, and keywords, app name, title are different for each country available in App Store. But, for some reason only few keywords are ranking. And for some reason they are in France(anki keyword) and US(different positions from 100-200)
But, from 100~ users that come from ASO - I received zero purchases and no one started my free trial.
Not sure where is the problem, at this point I want to give up. I spend more then 1 week researching for good keywords, app name and subtitle.
So, want honest feedback about my app. Like, how bad it is? Is it complete fail at this point or there is some chances to improve my app somehow?
Also, I have no idea how to find negative feedback about my app. I have six 5 stars ratings and 2 positive reviews, which is good. But, without negative feedback from users - I do not know what is wrong and what can be improved. Any idea how to collect negative feedback?
