Soulver is a smart notepad with a built-in calculator. It gives instant answers to any calculations it finds in your text. It's a better way to work stuff out than with a traditional calculator, and a more lightweight tool for quick calculations than a spreadsheet.
A playground for ideas involving math
Soulver is great as a simple calculator replacement. But it really shines when you use it to explore different scenarios and experiment with numbers. You can you use words and numbers alongside each other and you almost never encounter an error. And all your work is automatically saved for you so you can reference it later.
A better math machine
With Soulver you can see and edit all your calculations, all the time. Unit conversions, including live real-world and cryptocurrencies are built-in. Use headings, labels and comments to give your notes structure, and enjoy automatic formatting features and tasteful syntax coloring.
Take a load off your brain
Soulver comes with a set of natural language functions that make it easy to do common operations. For example, working with dates, times, percentages and proportions is easier than ever. And we're always thinking of new ways to make common tasks involving numbers more natural for the human brain.
An easy to use, versatile tool
Soulver comes with a stack of handy features for doing multi-step calculations. For instance, you can reference previous lines, kind of like a spreadsheet. And like a programming language, you can assign names to numbers and use them as variables in your calculations.
A total at the bottom automatically adds up all your line, and you can make subtotals of specific lines.

OpalCalc is a brand new type of calculator for the PC. As easy to use as Notepad or a word processor, OpalCalc allows natural language in the sum and multi-line support so you can go back and adjust your previous calculations on the fly.
For years, PC calculators have been trying to copy handheld calculators in both functionality and appearance. OpalCalc sets out to disregard previous conceptions, and instead we considered how a calculator should behave with a full keyboard in mind. The result is simplicity itself, but with almost spreadsheet-like capability.
OpalCalc features include percentages, currency conversion, custom functions/variables, excellent documentation, colour coding, lightweight size, configurable GUI, hundreds of measures and functions, and lots more. The full version can be obtained with a donation of any amount (even a few pence). There is no time limit in the 'lite version', just a 5 line limit which is very useful for most purposes.
