“Go-To” For everything!
I am a self-taught Astrophysicist, Astronomer, and Rocket engineer (simulated).
I searched a long time, through a ton of different software to make unit conversions or specific mathematic formulas, easier. I then found 12 in 1 Calculator.
Very intuitive design, and has such an incredibly versatile library.
I really enjoy reading my biorhythm statistics!
I recommend this if you’re anything like me, I love chemistry, geometry, math, mechanical engineering, (coding soon). I do it all, and 12 in 1 has it all!

The best at conversion
Better than any I’ve tried. Includes virtually every option.
Crashes on 14.3
Was great now always crashes on launch
Bummed
I have used this calculator for years. Very disappointed that when I finally needed the mortgage calculator that I can’t print or share the amortization table. Reason for dropping my review.
Great calculator other than that.

Currency convert bug
The currency convert bug remains 😔
Absolute Best All Trade Calculator for iPad!
You won’t find anything to come close to handle whatever calculation you need!,
Thank you!!
Thank you!!
The Best iPad Calculator!
This is a great app, you don't need any other calculator at all and it takes full advantage of iPad's HD. Plenty of tools. The best deal for the price!
Skin pack
Skin color orange doesn't work. Only reason I bought this calculator because it reminded me of LCARS. Please fix and yes I bought the skin pack.
Just perfect
There is so far no better investment I have made on the App Store, I've been an apple user for 8+ years and this is my very first review I've written. I am yet to encounter any problems and if you are either in college or financing this calculator is perfect for you. Personally, I'm in college and I seriously doubt that I will ever encounter an equation that this calculator cannot handle. 10/10

bio rhythm problem
when switch to bio rhythm that interface not show probably, and could not switch to other function.
Significant information, quick to fix
I am impressed by the response of the team. I found a small glitch, reported it and received an email within a day. They quickly fixed the problem plus a few more I had not noticed. Well designed format.
Terrific app UPDATED
UPDATE: iOS10 initially disabled this calculator, but the developers have made it whole again, including the currency converter (which, alas, doesn't work on the iPhone version.) That said, this is the best iPad calculator I've found.
ORIGINAL REVIEW: I can't imagine needing any other calculator. I use it mostly for unit conversions and a little for statistical functions, taking advantage of a tiny fraction of its capability. This calculator is intuitive, very easy to navigate and use. Highly recommended.

Still one of the best calculators.
Covers many useful functions with input arrangements arranged for the function being calculated. The inclusion of a periodic table complete with element descriptions and videos explaining many of the elements. Cover conversions, time, statistics. It will even figure your tip for self or numbers of eaters.

Very nice app, conversion selection rather confusing
My go-to calc app now, though I was initially confused by the conversion selection panel. Took a long while before I realized that I could actually select multiple units and convert among them instantly.
Also, rvs160 is mistaken, in that kilo/mega/etc. prefixes are technically restricted to the decimal (base 10) world. The XXbi- prefix standard (kibi/mebi/etc.) for base 2 counting is at least 15 years old, and is correctly implemented by the author in the conversion panel.

Great App!
This App functions perfectly. I've had it for about a year and have never had any problems with it through with any of the iOS upgrades. If you need a multi-function calculator that works, I recommend this App!
Love It
I loved the free version so much, I upgraded to the pro version to, in part, support the developer. I appreciated that the free version had no ads, which made my upgrading feel more sincere. Additionally, I'm glad I did! This version is PACKED with features! I particularly like the date/time calculator since this helps me in my business, which is the other reason I upgraded. I also perused through the app and saw many other features that I didn't originally know about, but was glad to discover. And, after months of use, I'm still discovering features! Great job!

Cannot go wrong
I was looking for a calculator that would support RPN. I downloaded a couple that claimed to work on RPN and was disappointed to find that the developers did not seem to know what RPN is. To boot, this calculator may take over several other apps that I regularly use as a professor in engineering. I recommended the app to my children's middle school math teachers. For a dollar this app does more than what they need. Even if not quite as complete as some of the advanced calculators, the kids are not getting any more for the additional $130...

I upgraded from the previous version and added, or tried to, the optional biorhythm,
I upgraded to the new version hoping it would be an improvement but....... I tried adding the free skins, the biorhythm chart and periodic table, unfortunately these don't work. I tried the "contact us" from the menu and that didn't work either. Pretty disappointed especially since one of the additions cost me. Hope they fix this.

Great FREE calculator
I really like this app - I have tried many other free calculators, and they all have either blocked functionality or they run ads and nag you with pop ups. Not only does this app not do any of that, it has far more functionality than most of the other calculators I have tried - the graphing feature, works quite well. It also integrates and differentiates. A great calculator app.

12 In 1 Scientific Calculator's Clock...
I thought, "An ideal Scientific Calculator", but then, the Time and Date (World Clock) feature went nuts! It was doing fairly well, but then, the Seconds Hand began "ticking" at a rate of about 5 seconds in 1 second! It gains about 5-7 minutes in about 2 minutes! Absolutely useless as a time keeper. Otherwise, 5 stars! However, if the clock isn't accurate, how can I know if other features are accurate? Until this is fixed, sorry, but only 2 stars. And, why not make it a digital set of clocks. Very disappointed in this App! Fix this problem, and I will gladly rate it 5 stars! Thanks,
