Equalculator is an equation calculator. It is currently in the "pre-alpha" stage of development, so don't expect it to do miracles. You type in your equation, it will ask you for the variables and Voila!, it gives you the answer.

Evrika is a science simulator and advanced calculator, which is based on modules. Modules are libraries containing definitions of concepts that can be used in the simulation. By definitions we mean properties, actions, reactions, etc. Evrika is used for creating both simulations and modules, so you can build your own module of elements, then use them to create virtual experiments and simulations. Also, you can make advanced calculations. Evrika is basically an executable that reads and interprets code, outputing result. Each new version will offer new possibilities to define your elements and use them, so it is important to always have the last release. Of course, Evrika is backward-compatible, cross platform and free to use. In the near future an advanced editor and viewer will be created, so you can better manage your code and view the results.

The Film Stock Calculator is an application for calculating the film stock footage and cost for a film.

This web app uses the Google Web Toolkit, (currently version 2.6.1). No hooks to the Google App Engine are required, so the entire application can be contained on an HTML5 web page. The application is technically written in a restricted APIs version of Java 7, then compiled down to JavaScript. Any data storage needs use HTML5's data persisting capabilities Use this food storage calculator to help plan food storage preparedness. This calculator uses the three tier approach to food storage. The three tiers are: 1. Normal perishable food purchases like milk, bread, and ice cream. 2. Multi-month or multi-year perishable items such as canned goods, pastas and cooking oils. 3. Multi-decade non-perishable items such as hard wheat, sugar, and water.

A small command-line calculator, written in Haskell, that takes input like "14+(12+24)/(8.5-2.5)" and prints out the result. It's nothing special really, just a little project I did to learn Haskell.

A simple on-line calculator for high mathematical problems Version 0.1 will be able to manage with matrixes

HistoryCal is a practical calculator designed to work with historical dates and calendars. The calculator will allow you to work with many different world calendar schemes and calculate ranges and ages based on these calendars. The calculator also has a script language that allows you to create variations of the built-in calendars: calendars that shift the new year to a different day; hybrid calendars that switch between schemes; local observational calendars that depend on a particular location; year counts that change for specific eras (regnal calendars) and calendars that require adjustment due to subtle differences in calculation.
