Optimized for macOS 12 Monterey. Native both for Intel and Apple Silicon Mac

TS Calc implements numeric resolution of calculation models you can use for any mathematical technical problems.
It is a complete different approach to solve math problems respect to the usual one using a spreadsheets.
Document based. You can create a different documents for any model to solve.


• A list of equations solving the problems
• A list of variables used by equations (also auto inserted while you input equations)
• A list of constants used by the equations (also auto inserted while you input equations)
• A description of the problem in RTFD with rich text and images


• The equations are automatically solved and output value filled
• Which functions is used as input for any variable
• Which function is used as output for any variable
• Which functions is used as input for any constant
• Which variables and constant as input for any function
• Which output variables for any function


• Uses standard math syntax with parenthesis and standard operators
• Provides and extended diagnostic tool to catch errors
• Automatic insertion of variable parsing equations
• Popup for insertion of available functions
• Variables and constants have a table listing them
• Uses a math calculation engine entirely developed internally with an impressive speed and efficiency.
• Variables and constants can also be manually added and edited
• Import/Export of functions and constants
• Allows to see where variables and constant are used and how
• Any variable can be moved to the constant table and vice versa
• Any view offers an info panel with additional info
• Can specify acceptable range value for input and output
• Values can be imported/exported using a powerful import/export functionalities
• Up to 16 decimal digit precision
• RTF note to provide additional info regarding the document

Almost there

I've been using TkSolver since it was first release in 1984. This app is getting there. ChicoSolver was close, very close. The biggest drawbacks of this app is that it is clunky to input variables and equations. When you hit enter it should give you another line to start another input. Also, it would be nice to see variables solved, constants and equation all at the same time. This app has great potential for people who see equations. Another thing, the variables and constants should atuo popuate as an equation is enter, a huge time saver.
