Arcane Tracker is what I use, but YSK there's also Elephants Guide. [Play Store] [reddit thread]
A bit off-topic: I play a lot on my phone also, and recently found this one to track my games: https://play.google.com/store/apps/details?id=com.purplesquare.elephantsguide Hope will help you :wink:
Back on topic: I will definitely try this one. I got kicked my arse with my Aggro Pala and Tempo Rogue by decks looking like this one. Imho next month the meta will be really dominated by Pala and Priests and Locks, we might see decks like these more often I guess...
If you have an Android phone there are a couple options now! Check out /r/ArcaneTracker and Elephant's Guide. I think ArcaneTracker has track-o-bot integration, and Elephant's Guide has added match tracking into the app. (/u/Stepwolve fyi)
personally I like elephant's guide tracker because you can build decks offline and it will pick up on what deck you are playing automatically. the only wierd part about it is that you have to launch hearthstone though the tracker app, but I built a automate task that will do it for me. the UI is nice and it has a bit of customization. not perfect, but its still in beta.
edit: apparently 7.1 messed with the tracker apps and they aren't working right now. I mainly play on my computer so i had not noticed.
I've used it a couple times and haven't had any issues. That said, have you tried this app? I am the dev, but it sounds like a good fit.
Try Tracker for Hearthstone. It allows you to import and export decks using deck codes.
