Sorry to hear about your software woes. I'm a pretty high end software guy who's been stuck in a codeless managerial role for three years while my teams have all the fun. Longest time I've gone without coding for 30+ years. Miss it badly.
Anyway, I'm open to a string of weekends worth of work to do the full deal ... custom iOS/Android apps (React Native) and web app (React) with real-time integration with whatever you all want (gmaps, supercharger.info, this forum, etc). I have some underused AWS instances lying around which could scale to 100s/1000s of users, with basically the same power as ... Netflix?
Best of all, you could all design the app you want... custom everything. Keep it lean and build out fun goals, filters, social stuff, etc.
And just for fun, no money, no advertising, no patreon or anything. Legally I can't do that anyway. Open source is only option.
Anyway, just a thought. Don't want to steal anyone's thunder. It's just really very easy for me to do this stuff. I make name-brand highly scalesble/configurable apps all the time and it's not much fun. But having a reason to obsess more about my Tesla. That's a win.
Again, don't want to diminish anyone's efforts or wade in and make noise.
