History Tape.
Every calculation you enter gets saved to the history tape. Refer to calculations later or send them right back to your current calculation.

Expression View.
Calcbot's original expression view allows you to see everything you have typed so you'll never forget what you entered or miss a typo.

Apple Watch Extension.
Perform basic calculations, conversions, calculate tips, and split bills right from your Apple Watch.

Convert any of your calculations with over 500 units across 22 different categories including auto-updating currency rates.

Fave a calculation and get instant access to its result via the Favorites Key. No more cryptic memory keys.

Scientific Functions.
Rotate your device into landscape mode to gain access to common scientific functions.

Get instant access to scientific constants like Pi, Atomic Mass, or add your own*.

Round for Currency.
Have all of your results rounded to two decimal places.

Customer Reviews

The best is back!

Version 2.2 Update: I’m so happy that Calcbot now supports split screen and slide over. It’s a big help when wanting to do a quick calculation on iPad where Apple doesn’t give you a calculator out of the box.

Calcbot is my favorite calculator app. It keeps the simplicity I want and adds the little extras I desire. The tape feature is great. I really like enabling the currency option because most of my calculations involve money. Being able to easily convert units is icing on the cake.

This is a huge update to Calcbot and it shows. So much more than just a coat of paint.

awesome but calculations are SO SLOW

idk if anyone else is having this issue but whenever i press the “=“ sign it always takes at least 4+ seconds to calculate... I know it pre-calculates before but in order to save a calculation in the history, I have to press the equal sign. It’s literally only when you press the equal sign that this app lags. It makes no sense because I have an iPhone 8 so I’m sure the A11 bionic isn’t the problem. Please PLEASE P L E A S E fix this bug and i’ll gladly change this review to 5 stars; the rating it should
and i’d gladly give! i love you developer pls dont roast me

Love this app

But it would be great if there is option that C (clear) is always visible.
Sometimes I have much calculations, and often have to delete and start all over, holding back button to clear is then very annoying.
Maybe to have option to remove fav button, and replace it with back, and back to always be clear would be great.
I really dont see why would I fav something in my callculations since I already have history.
