I typed in "inskate" and "In Skate" into Google Play in Canada and nothing came up. Closest thing was "Figure Skating Coaches" app.
I'll give you general advice that I give to everyone I encounter who is trying to be successful with apps.
As you probably know, creating an app that's popular is very very difficult. 7-8 years ago people had more curiosity about apps so most had 30-50 apps on their phone that they used even a little. That number has reduced greatly because the excitement over apps has worn off and an app needs to be amazing for people to install it and use it. Now, people only have 15-20 apps on their phone on average, according to ComScore statistics.
Many people that I meet approach apps (and web sites and other businesses) the wrong way. They build something they like or think is interesting and then say "Ok now how do I get people to use this...?" and they go off trying to 'market' it. That could be a very long road that might not get you anywhere. If it does, it may take a few years of time/effort/money to convince people to try it and keep using it.
The thought process should be "people have X problem....or need to do Y task. And all the solutions/apps/websites/tools out there are not that great. My app is going to do this for them way better/easier so they will want to use it" Focus on this kind of thinking -- to serve a clear need for your user and do it better than anyone. You will end up having to do less marketing because people will open the app, think it's amazing, and tell people about it without you doing all the work.
This goes back to my 'features and benefits' question. Zero in on how you are serving your users in a unique and better way. This is your advantage.
The saying is, if you have no idea where your users are coming from and how they heard about you, you're on to something. That's where you're trying to get with your app.
Happy to answer any specific questions here or through DM if you want more specific thoughts.
Good luck!
