What is the best App to live stream games and keep detailed stats?
We do have an app. In our setup, with the groups we work with, we voluntarily don’t live stream. The app can be used either as a highlight reel generator or a more thorough coaching analytics platform.
Having said that I really don’t want to turn the forum into a listing of ads so if you’d like feel free to ping me via DM and I can send you some info. 
On the topic, something you may want to consider because I truly believer there is no “single best app”: Make sure you decide on what you are looking for and the specific use case you have in mind.
Here is what I mean.
Streaming ? You can do simple via Cloudflare or Youtube live all the way to mega complex with hardware, starlink and redundancy.
Stats? Vanity stats via 6-8, basic stats via Claude or GPT by snapping a pic of the score sheet, advanced with analytics…all the way to Huddle (that has its own flaws)
So mileage varies a lot with apps !
