iOS 7 Users Update:  (9/25/2013) We are working toward a fix with the “text saving” issues in the audio & stopwatch modules – please note that the app will save your recordings and times, but will not label them -you are able to edit the audio name after saving.  

We also are aware that many of you are being “dumped” out of the ScorePDF module.  We are currently working on the solution for this as well.   These issues are currently affecting both the A.P.S. MusicMaster (iPhone) product and the A.P.S. MusicMaster Pro (iPad) product.   We are currently unaware of any issues with iOS 7 and the A.P.S. Tuning Trainer.
