What are the main advantages of oRanges Calculator?

Of all its features, oRanges Calculator developers highlight the following ones:

oRanges range constructor

This tool allows you to mark the selected hands with a certain color, choose the frequency of actions with them and set a name of the action itself. Each hand can be assigned up to 4 colors with the corresponding frequency (weight) of the action. The created ranges can be saved as a tree for future use.

There is a statistics section that helps to determine the frequency of use of hands in different spots, which helps a lot when balancing ranges.

oRanges preflop all-in helper

This tool is designated to calculate equity against selected ranges and determine EV Call and EV Push in situations where an opponent is pushing you or a possible opponent's call to your push. 

Flop Texture Filters

This tool generates random flops with a given texture. It allows you to study how certain ranges will fall into the boards with selected texture. This tool will also find out how often flops with a certain structure fall out.

Fine selection of starting hands

Only by clicking on the desired hand, you will have the possibility to study all the possible combination of cards for the hand on a pop-up window.

Flexible hand-weight assignment system

All hand in ranges differ in the percentage of play. For example, pocket aces and pocket kings are played in 100% of the cases, and small pairs (22-66) in 50%.

oRanges Calculator allows you to fix the frequency of use of the hand in a range using the weight of the hand. This can be done in two ways: using a slider located above the table of starting hands, or through a pop-up window that appears after clicking on a certain hand.

Hands with weight in certain ranges (up to 20%, 20%-40%, 40%-60%, 60%-80%, more than 80%) have the same color. The number of assigned weights is unlimited and allows you to import ranges from PioSolver.

oRanges user filter

Custom filters are used to remove or add hands to standard oRanges Calculator statistics. For each post-flop street, the software has a separate user filter.

User Filter allows you to create new unique statistics by combining or modifying standard statistics, which can be used for quick analysis in different situations.

Filters can also be used to divide standard statistics into groups.

oRanges range tree

Working with ranges in the tree is greatly facilitated by the Drag & Drop function. Folders with ranges can be easily moved and copied just using the mouse. New branches of the tree can be saved on a file for further use.

In addition, oRanges Calculator has:

  • MacOS Support
  • Low price, the license for one computer costs just $15
  • The trial period is 7 days
