Still one of the good ones! I had this app before and removed from a previous phone for space. Just never had installed on my (then) newer phone. (Using Note 3) installed tonight  downloaded quickly and was ready to calibrate. Calibration took a couple of trys and did end up using the figure 8 method to do so. (Explained in app) Went from low accuracy straight to high. Everything lined up perfectly. Such a fun app that's also very functional. Now I'm eager to see if it will work just as well on my new(er) phone upgrade.. Note 5.
