RPN 28x Calc
Version History

Version 2.2.1

Januarr 2016

  • Added an option reduce motion in the startup animation. Prior to iOS 8, the default is "Off". On iOS 8 or later, this setting will be pre-set to mirror the value of the "Reduce Motion" setting of the General > Accessibility pane of the main Settings application. However, once the value is changed in the settings panel within the app, that value will be retained and used from then on, irrespective of what may be set in the Settings application.
  • Fixed: The grey Copy & Paste Shortcut bar will no longer appear, whether or not Bluetooth is enabled. Previously, it would appear when Bluetooth was on, and the bar would then stay until the app was restarted.
  • Updated the startup animation to animate the app icon rather than the entire launch image.
