Counting devices have come a long way since the days of the abacus and most of us now have a calculator to hand on our mobile phones. Many of these default calculation programs are pretty crude though and are far too basic for the likes of scientists, maths students or financial workers, who often need powerful equation-solving tools in their daily lives. Luckily there are plenty of third-party calculators you can install that will make your phone as smart as Stephen Hawking. Here are some of the best:
- MxCalc SE – Programmable calculator that specializes in financial mathematics
- Abakus – Perform complex engineering and business calculations on your Sony Ericsson
- Best Calc – Displays 24 digits and performs a wide range of scientific functions
- Calcium – One of the most gorgeous and enjoyable-to-use calculators you’ll see
- SpaceTime – Advanced Pocket PC calculator with support for 4D graphs
