Calculator HD Pro App Reviews

This Calc is sooooooooooo much better than the one that ships with iOS. If you find yourself using the Apple one more than once a week, this calc is WELL worth the upgrade. You’ve been warned. 😃

Best calculator by far on the internet! Thanks!

Exactly what works for me

This is by far the best calculator I’ve ever used. Thank you very much for making it available.

An accurate, versatile, graphically, interesting, multi themed calculator. Perfect!

Update 2025: This is such a vastly superior calculator. Lots of small but great features that make it so. I love that you can easily turn sideways to quickly see the "tape" results of previous calculations. See description for more. Still my fav Calc! Update 10-1-2018: still my fav Calc! Update: 6/13/2019: & Still! :-) Update: Sept 2021. Still like it.

i just love messing with this for fun even when i have a calculator in real life and have the app apple gave me :D

Has been reliable and offers anything from basic to scientific calls. One of the best things I added to iPhone

Simple, straightforward calculator with all the functions I need. Highly recommend.

Calculator HD PRO is a user friendly calculator with an attractive display .

I’m happy to have it on my home phone screen.

I really enjoy using this app. Very easy on the eyes and like that it saves your calculations.

Only thing it lacks is a tax button to to set a tax rate.

Two things I want in this calculator: 1. The ability to sync with all my iOS devices 2. The ability to manually sort the history tape

This is the best calculator I have ever seen. More functions than I will ever use.

This is my go-to app for every day math. I’m a detail oriented person and, although retired, keep careful daily logs, many of which require the basic functions of adding, subtracting, multiplying, and dividing plus percentages. I love the layout and seeing a log of all my entries allows me to check quickly for data entry errors. I bought the ad-free version because I hate ads, love the app, and want to support the developers.

Great overall calculator. Got a new phone and was looking for this same app I had on my previous one. This is the ONLY app I paid for no ads. It is totally worth it. I am so pleased they still have it available. Thank you.

I have used this calculator for years. It is by far the best, most useful and intuitive tool on my phone. Thanks🤗

Best calculator program ever, hands down

It has an easy to use memory feature followed by an easy to use backspace when you’ve made a fat finger error. Also with parens you can string along a simple equation. In the horizontal position you scientists and mathematicians can have a blast. These features without ads were worth the one-time fee.

Good size keys. Full scientific in either portrait or landscape.

Best all around calculator for the $.

It keeps track of my input so I can clearly see if there is an error. It is as simple or complex as I need it. I like it ...

Best calculator app I have used in years! Paid for the no ads, well worth it. Use all the time.

I like it very much. It has all the features I need. Having the tape, ability to send to others and able to file. I have really liked this calculator ever since I saw it. Have used it more than any app I have ever used.

The best caculator on IOS. Enough for the basics and then some on the scientific side. Excellent well thought through design and user friendly. Updated regularly.

Thank you for developing!!

I’m a retired engineer. I no longer have the need for lots of computer power to solve design issues. This app serves me well.

I use this Calc for groceries, check book, recipes, everything. But the one feature I really want the developers to add is the ability to manually sort the result lines after calculations are complete, like the way we can manually sort the history folders after we create them.

I'll be using this for a while and it helps save my calorie count. I can't believe Microsoft and apple don't save the history of your calculations anymore? Update* I forgot that I love how you can customize it.

Used this forever on my first (ancient) iPad. Awesome, totally awesome!

I'm so grateful for the multiple features with this app. A huge highlight, that's super meaningful to me, is to easily track my calculations along the way, and having a back space feature. I love being able to process and think through intentions with the help of this app, that saves me lots of time, in harmony with my unique learning style. Thank you!

I bought it because I love it and got tired of Google asking me to sign up when I already am! I like how it keeps a running tally and let's you know your total as you go; as well as running a "tape" to check the numbers I put in and make sure I got the right ones. It's very helpful in having a back button and a clear button. I really like it.

I use it for my pre Calc studies regularly. Better than the HP 89

You can't get a better calculator. Would like RPN capability.

Works great had the free version but all the adds were getting. Bought the app and am quite satisfied

But, does it support family share? I have the pay version…

I have used this app now for over a year now. I have two other apps like this one , but this is the one I always use and is more useful and easier to use. (So I just deleted the others today). Highly recommend this one over others.

I'm a minimal-use calculator user and find this calculator to fit my needs well. Used another for a while; like this better.

Have paid for and used ma y of the calculators available in the App Store, they’re all pretty much the same, I just like the 3d feel and colors of this one.

I like this particular calculator. Reason being it shows me my numbers for golfing and it makes it so much easier.

I use it almost daily. It is on my phone so it is my go to calculator. Easily accessible and easy to use. Thanks so much for the handy tool.🤗

I absolutely love this calculator! It has been my go to for years. Over the past month an Apple pop-up warning appears every morning indicating that the app needs to be updated and asks if I want to keep the app or delete. Is a fix coming soon?

Use it all the time. Can do almost everything. Try it. You will love it!
