In a surprisingly large part, our reality consists of calculable problems. Should I buy or rent? What's my ideal calorie intake? Can I afford to take this loan? How many lemonades do I need to sell in order to break even? Often times we don't solve these problems, because we lack knowledge, skills, time or willingness to calculate. And then we make bad, uninformed decisions.

Omni Calculator is here to change all that - we are working on a technology that will turn every* calculation-based problem trivial to solve for anyone.

Eventually we will solve thousands of problems so that every time you get any problem, you'll know that Omni Calculator has a solution for it. We will help millions of people make better decisions every day. We're not quite there yet - right now we're just testing the interface and gradually adding functionalities that will make that vision a reality. Enjoy!
