Download Pro Calculator

Version 1.2 is now available for download on Apple’s iTunes App Store.

The Download Pro Calculator (DL Pro Calc) is an iPhone application designed for software professionals and download power users looking to estimate the download time and the storage media required for any given download or file transfer.  It’s available now on Apple’s iTunes App Store.

Before downloading a large software or movie from the Web, simply launch the DL Pro Calc and enter the file size (in MB, GB, TB or PB).  The DL Pro Calc will automatically display the estimated download time for the most common connection speeds in a scrollable list.  Swipe the scrollable list to the left, and the DL Pro Calc will display the storage media (CDs, DVDs, external HDs, etc) required to save and store the download. Want to know the file size in GB (default is MB), select the GB button; same approach for converting to/from TB and PB.  To reset the DL Pro Calc screen for another calculation, simply select the “C” button or shake the iPhone.

The DL Pro Calc offer 3 settings for customization through the Preferences view accessible via the “i” button in the lower right corner.  Select from 1 of the 3 Backgound Color to change the look-n-feel.  Adjust the Network Overhead (default: 10%) to apply it in calculating the estimated download time.  Turn Precise Math (default: ON) on/off to control whether precise file size (1 kbytes = 1,024 vs 1,000 bytes) should be used in storage media calculations.
