How do you guys keep track of everything?

Just had my second game of AoS, 1000 pts. Currently I’m just using the GW app for all my info. Needless to say it was a lot of clicking and going back and forth and I still don’t think I kept track of everything I could do. Is there any resouces or printouts that you guys use to better keep track of everything for your army? I thought about getting the faction card pack but I’m not sure. Any advice is great.
