Frank Illenberger I have just released pianoscope 1.6 to the App Store. Thank you all for your help with the beta test! These are the official release notes: New Features: Czech translation of the pianoscope user interface (Kudos to Milan Debelka!) Changes: pianoscope does now respond better when striking notes with a fast repetition rate in the high treble. Fixed bugs: On very small devices like the 1st generation iPhone SE, the tuning view layout could be wrong if all on-screen features were activated. On some devices, the app did sometimes not restart audio recording after the device had been put to sleep. Sometimes after beginning a pitch-raise tuning, the tuning view did not react to any notes until a different note was selected manually. If only the custom stretch was edited in a tuning style, the change was not saved. The onscreen keyboard could get a wrong size when pich-zooming it in portrait mode.
