what size boat do you have? i wouldn't go out on erie in anything less than a 16' or 17' deep v. and them only on good days. as for weather apps theres some good ones out there but i don't know them off hand. you can do a search on the web for lake erie weather. i just use the weather channel on my radio and the weather forcast. but mostly i use common sense. once you get the safety gear you can launch and be fishing the reefs in 10 minutes. you'll also want a good drift or trolling bag to slow your drift if needed.
