Hey all, I built a simple, but not pretty, set of tools in my spare time for Diablo. I use them myself all the time and wanted to share with others and see if other people find them useful. While not nearly as robust as the amazing http://d3planner.com, my tools are just a quick way to get some simple information about specific things. As a bonus, all the tools work great on all devices including mobile.
Weapon Reroll Calculator: A helpful tool to quickly see how different reroll options will affect your weapon. Use it to see if you'll get more damage by rerolling base damage or Increase Damage % and more. http://rerollcalculator.com
Paragon Calculator: Use this to calculate your total paragon level when the season ends or use it to see how much experience you need to get from one level to another. http://rerollcalculator.com/paragon
CDR Calculator: Calculate how different combinations of CDR will affect the skills you use. Quickly check what your uptimes, downtimes and the time between repeated uses of the skill. http://rerollcalculator.com/cdr
