Really annoying for widgets ### 2/5 — Was awesome. *2018-12-09, version 4.0.6* The history used to save all of my previous calculations, which was super helpful. Now it doesn’t. Don’t know why. Frustrating. ### 5/5 — Works like it should *2017-12-12* Great developer support. App works good on the iPad, which is missing a stock calculator. **Developer response:** We've rolled out a fix to this problem. Should be able to work now. If you encounter any other issues, please reach out and we'll help you resolve it. ### 1/5 — No scientific calculator????? *2016-09-02, version 3.5* You are making it the worst one V3.6 you can't select numbers from history and there is No scientific calculator I like the previous version can't change it to scientific calculator!!!! ### 1/5 — Error *2016-07-06* Show ERROR in result when you arithmetic many numbers without equals. Also, long string is not visible in full. And, you can't get back to any result in history - you need start everything over. Useless. ### 4/5 — Good App *2016-05-27* The implementation of parentheses puts this app ahead of almost all other math apps. The only limitation- only 2 significant digits after the decimal point. ### 5/5 — Simple but good *2016-04-18* I love this app it's awesome. I like the fact you can delete your history with just a swipe at a time. Wish the (c)button would delete all but it only deletes one number at a time. ### 2/5 — Not good *2016-04-18* This would have been good if it gives you the right answer but a simple calculation is bad,so would NOT recommend this specially if your a machinist. Example 2.756 -.551 and it gives you an ans. of 2.2 instead of 2.205 ### 1/5 — No scientific function *2016-04-18, version 3.3* In the description this app compares itself to a graphing calculator, but I can't find any way to have it perform anything more than simple addition and multiplication: no log, no exponents, not even any trigonometric functions. This calculator just doesn't do anything useful. ### 2/5 — Decimals *2016-04-18* I can't make an operation with decimals like 8 x 0.1 because the app fails. ## Frequently asked questions about Kalculator ### What makes Kalculator different from a standard phone calculator?
