Ratings and Reviews
Goooooooooooooooooooooooooood
I like this app because I like how you can scroll back and look at the numbers you've entered. It is simple and easy to use. Using decimal fraction, and the mixed number button is a real time saver. It also looks cool when you are doing your work. This calculator definitely beats the standard one that Apple provides. I honestly think this is a cool and better calculator then the ones I have used before.

Thank you for taking the time to write a review, it is greatly appreciated! I hope that you enjoy the jCalc 2.0 update :)
Simple is good
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.

Thank you for taking the time to write a review, it is greatly appreciated! jCalc 2.0 was a huge update and took longer than anticipated, and I made sure to include the ability to lock it in landscape mode :) I hope you enjoy the update!
Jcalc
This calculator is really helpful. If you don't have a calculator with you, you can download this app on your iPhone. One thing that I didn't like is that this calculator isn't a scientific calculator. It would help with even better since I am taking Geometry but other than that I really like using the calculator. It's really helpful and I definitely would recommend this to others.
