I worked with a friend to created and release the warchest apps some time ago. We went down the same road you did but had to scale back the project as no one was interested in supporting the app and there was not enough interest in the concept to merit the hundreds of hours we put into it.
Not saying there isn’t an opportunity but it seems very few people that would actually use the app are playing AA.
One suggestions is to focus on Ios. We had thousands of downloads compared to less then 30 on Android.
If I can help provide any direction let me know.
