About us

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 to break even? Often, 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 technology that will make every* calculation-based problem trivial for anyone to solve.
