Dire Studio updated their popular ShutterCount app (MacOS and iOS only) with a rich feature pack:
The Plus Pack contains graphs and forecasts, outdated firmware warning, simple time and date synchronization and history log duplicate removal. The Plus Pack is an optional add-on, and can be purchased from within the Mac and iOS versions of ShutterCount.
The Plus Pack’s graphing and forecasting features take advandage of your existing history logs, with no need to round-trip the data into another application to visualize your camera usage habits. ShutterCount also knows your camera’s shutter durability rating, and calculates the forecast based on that number.
