Diagnostics Dont work

I have had Hum for three months now. Until this week I thought hum worked great. My check engine light came on yet hum says my car is working perfectly. After calling their "trained" support staff line the woman assured me that if anything was wrong with my car the app would notify me. Well almost $1000 later, my car is fixed. Fixes included a new battery, computer failure fix, and a few other things. The bottom line is, this app should have notified me that my battery was completely bad yet it still gives me a perfect bill of health. Worthless.
