I didn't click your link, but I checked for the app in the Google playstore and I didn't see it there. I make use of an android phone and I'm not the kind of person that downloads just any app I see online and not on playstore, because they are likely not going to be safe… I know that for sure. So I will suggest that you should get your app on the major app stores like Playstore and App store for iPhone users. No one is going to download your app if you are just giving them a strange links to downlaod it, everyone is staying safe these days, cause there are lots of happening in this world. That's what I have got to say, you do what you like.
