App has serious bugs
Spent the $12 and downloaded this app. Was the most expensive app yet have purchased. Waste of money. PV Master would not open either on my iPhone 4s or iPad gen 4, with latest updates installed. Tried everything to get apps working. Called apple support and ran thru all techs ideas to no avail, deleted and reinstalled on both devices again. Still didn't work. App will only flash up onscreen for 1 second then disappear. Save your money on this one folks.
