• Performance improvements.
Simple. Powerful. Easy to use. jCalc is a scientific calculator that makes sense.
Enter fractions and decimals:
•  [.]  = 1.2
•  [n/d]  = 1/2
•  [n/d]  [Nn/d]  = 1_2/3
• 1–16 decimal places
• Irrational, rational, decimal and scientific results
• Trigonometric functions in radians, degrees and gradians
• [Ab/c] ⟺ [a/b] ⟺ [a.b] ⟺ [a.b×10^c]
• [del]: Delete last entry
• [C]: Clear current expression
• [AC]: Hold down [C] to clear all entries
• [sci]: Scientific calculator
• [2nd]: Additional functions
• [ans] Memory of the previous answer
• Automatic parenthesis
• Percent button
• Scientific notation
• π button
• Powers and exponents
• Logarithms and logarithms base x
• Trigonometric functions
• [hyp]: Hyperbolic functions
• [prob]: Permutations, combinations, and factorials
Hi John, great to finally see this update. One question and suggestion. The original formate in a dark back ground with bright colors as the text, could you please offer that as well? Also, I am unable to get my simple additions to layout in a running tape format like they did in your original version. Could you either tell me what I need to do to get that running tape format or along with the original color scheme of Version 1.0 I asked for could you please offer that as well. Again, so happy to see Version 2.0!! Thank you!!!
Loved this app until the latest iOS update. When you open the app, the display is not working correctly. About 1/4 of all characters on the page are displayed. If you tap them one by one, they display correctly.
This is my favorite calculator. I’ve tried many but always go back to this one. It just works well for me. Thanks for the update to iOS 11.
I actually like the fact that there are only the basic keys because it means bigger buttons. I like the running tape feature too. I only wish it had the option of locking into each of the layouts. I need to use my phone calc strapped to my wrist at work but the only way to lock the screen is in portrait mode. Locking landscape mode would give this calc a feature that would set it well above the others. It's still great for what I do with it but it would be a dream come true with its large keys and a locking landscape mode.
I think that this app was very useful although I would have liked to see some other tools. I wish that they would have had tools such as sin, cosin, and tangent. Also it good have used a squaring tool and a square root.
jCalc is a pretty standard calculator. It works well and I like hat is is colorful and you can change the theme. Also the i button is very informative for those who aren't sure they are correctly using a calculator. However, the fraction, decimal, and percentage buttons don't work, so that should be fixed. Overall, it is a pretty good calculator app.
It's like a normal calculator. It's helped but I just didn't like that fact that it doesn't have all the signs and buttons I need
Apart from having easy access and simple mechanisms, I love the different color-schemes and themes it includes. Making it all the more interesting!! So great!!
It's a good app for managing your calculations. I find it very used for mathematics and science.
This app is a good app once you figure out how to use it. I wish that there was a tutorial in the beginning that taught you how to use it, but after a while I figured it out. I like how you can swipe down and see all of your work.
I like this app because it is extremely helpful and has many options to choose from. I can use this calculator for my math class and In my chemistry class when dealing with hard mathematics problems. I definitely recommend this app for people who need a good calculator app. Incredibly useful
This app is very useful and easy to use And very artistic. There are many settings with different types of calculators with different colors. Another thing i like is in the settings is it gives you answers to mixed numbers and converted numbers.
Very good app. It is very helpful especially when using it for fractions and decimals. At first it is confusing, but after you use it for a couple days it becomes very easy for math. I just wish that you didn't have to pay for additional features that would regularly be on a calculator.
i actually like it but its just more convenient to swipe up on my lock screen & click the calculator button, but its still a good calculator.
I use it for my geometry class and it works well.
This app is a very good application to use. There are many options on it. It's hard to use at first but as I used it every day it got easier. I'll be using it in my math class often. I recommend it for everyone.
Honestly, cool colors. Honestly, when I opened the app for the first time, I stared at the mass of numbers and words. There is no tutorial whatsoever, and when I tried to type the fraction 4/3 it only let me type the 4 and converted it to .25. Although A+ on the colors.
This piece of crap does not work at all you can't even use fractions which you know if your trying to find a calculator that uses fractions then you probably want one that actually uses fractions
I just downloaded this app Is great the thing i don't like is that you have to know the answer then it will convert it to whatever option you want, fraction, decimal, etc what if I want to add a fraction and don't know the answer? It doesn't let me know that, but if I know the answer then I could change that to the options but can't add fractions!
This is the worst it kept on giving an answer of.33333 repeating it was annoying don't nuy
