Great calculator. It has modules. Quite useful.
Even in the standard mode you can see your prior calculations by pressing a pen icon at the top right area of the calculator. The scientific calculator does logs and other standard functions. I use the unit converter all the time because I don’t remember the conversion factors. This was a fantastic purchase.

Great calc, but with a major flaw
This is really a great calc, but with a major flaw when in RPN mode. I reported the flaw repeatedly, with no fix and no acknowledgement of my reports, despite their promise in the help screen that they would ack bug reports and feedback. The flaw happens when the calc is in RPN mode, emulating a real HP RPN calc. It's about the key LastX. I am not going to explain how LastX should work - you either know it, or you don't, and if you don't, it doesn't matter; it means you are not in the RPN mindset. In this calc, LastX does NOTHING - it's totally, absolutely USELESS. I would have given it five stars, but because of their stubborness in handling - actually, not handling - customer's feedback and bug reports, I punish them with one star.

If looking for a Statistics calculator, keep searching
One of their calculator is a statistics Calc, and a sorry one it is at that. It has a small list of linear regression functions, some permutation and combination calculations but not even a standard deviation function. Forget about X2 function either or z values and probabilities, average, correlation, or even median. To call this a stats Calc is just wrong. I would rate it zero star if I could. Somehow they think inverse tangent, cosine, etc is part of the basic stats tools. Wish I could get my money back. Maybe they omitted a screenshot of their statistical calculator on their App Store description for a reason…

Being a must app on my cellphone for 10+ years
I’m a heavy user on currency exchanges and conversations. The currency updates had been a great help, I haven’t seen another Calc app feed this many diversions of math needs with in depth variations as this one. The only reason I give a 4 star is because lately the conversion update in the free version are about a couple days behind real time currency exchange. A must Calc app across my devices.

Well done
This calc app is the best I’ve used. I’ve only used it for basic math, whereas it has 8 or 9 other functions, which I haven’t used so I can’t assess those. I like the options for personalizing the display. At top right is an icon of rolled tape, which switches to a page showing the inputs for review. It’s easy to calc tax. If you’ve used a ten-key, it’s a bit different but easily adapted to. There’s no login or ID for it. I used it for a long time and finally (happily) paid the $7.99 to remove ads. But after deleting in error and reloading it, I have ads back again. I emailed them and I expect a correction. I recommend this app.

Hurray the best calculator is back
Perhaps during development of this upgrade, CalcPro was grayed out and mine was not opening with the latest IOS. I feared it was no more. I looked at other app and none came close. I confess I took a free ride but more I paying as I should have before. An app this good should be supported.

Great app but...
Functionality I give 5 stars. Having to watch Joe Biden every 5 minutes and itching waiting 5 seconds to skip ad -3 stars. BTW its only Joe Biden ads, no other type/kind of ad. Throw in some Home Depot or some 20-year-old telling me about testosterone levels and the 5 foods to avoid after I watch his 20 minute infomercial in which he repeats 1,000 times that any minute now he’ll share this information, idk “...would you join my campaign?...” and downloading a different calculator

Took payment, didn’t remove ads. Support contact didn’t work
Decent calculator that didn’t remove ads after money was deducted from my account . I will remove the 1 star if someone removes the ads.... A couple weeks later, I still have the ads, and they have my $8! Ok. They refunded and I rebought and the ads are gone :).

Used to be my favorite
If it’s possible to love an app I loved this one. It did everything I needed and I loved the tape. But about a month ago it stopped opening. I was busy with the family and holidays and this week tried to resolve the problem by deleting it and reinstalling it. I purchased the no ad version and thought I could just restore my $7.99 purchase. Nope. And no response from the support team. So I’m done with this app. I don’t want to have to deal with the ads or the poor customer service.

Not Accessible to IOS VoiceOver
I just downloaded this app and clicked to select the paid version without testing the app. I realized in a few taps that it is not accessible to IOS VO for the blind. Tried getting service to request a refund through the developer but, link didn’t pull up a contact form so, I’m leaving my feedback here hoping for a refund.

Sneaky Ads
Okay, but there should be ad disclosure, in my case video ad plays with finance pitch to students. I wonder if developers would like the same type experience, say rent a car and have the radio blast every few minutes while they drive? Very similar annoyance - making you hate their company and products.🤷🏼‍♂️

App crashes
Most current update that was supposed to fix “minor bugs” seems to have created a major one. This app crashes immediately when I try to open it. Hopefully this is fixed soon as I have used this calculator everyday for 4 years.

App shuts down unexpectedly
I just got the app today. I need a calculator that has a “tape” function, allowing me to verify my entries. With a few simple calculations, it worked as expected. But I tried adding >100 entries for an addition problem and it shut down. I thought that I could have pressed the wrong button, but I tried again and the app still shuts down when I press the “=“ button.

Ok app, bad customer services and scam like business
I paid the full price of the Calc Pro $9.99 used very sparingly, got an update version 6.9 and now the app is playing ads constantly and asking to pays another full price. Contact via them via email, and their website to no avail. Clearly the developers are running this App like a scam.

Cannot find contact
I bought this but still see Google ads. Why? Don’t know because I cannot find contact. Seems to be decent calculator but if I can’t get rid of ads I’ll eat the 8$ and get something else.

Great App/ fair amount of ads
The price for some of these apps is a bit more than I'm willing to spend. When I have an extra ten laying around... I'm paying for this v the dang ads.

Reads your clipboard without you pasting
Accesses your clipboard without me pasting. Used to love this app but iOS 14 not shows me that it’s grabbing my clipboard. Could this be how someone hacked your email, Facebook, or bank? This program has no reason to access my clipboard to function properly. Security risk.

Keeps shutting down
This calculator has been great, however now it shuts down on me every 10-15 entries. I would then have to reopen it and use it for the next 10-15 entries before it shuts down again. This is ongoing. Can you please fix this?

Disappointed
I paid for this, but after doing a couple of trial calculations, it simply crashes whenever I open it and press any button. Guess I can’t get my money back, but I will be deleting this bad product.

Can’t operate time value of money
Don’t know how to find the answer. With these types of calculations one has all parameters except for one, the one for which they want the answer. Not clear how to leave one blank so the Calculator provide answer.

WAS Great app BUT
This was a great app. I bought this app so I didn’t have to deal with the adds. I paid for It. It was mine to use because I paid Money for it. Then there was an update so I let it update. Just to find it had adds. So I have moved on to different calculators.

Financial Calc needs basic work
A financial calculator when set to two decimal places should always display two decimal places. And the “tape” feature should display like a calculator tape NOT a string of numbers. Fix these add a network IP calculator and it would be perfect.

Suddenly stopped working. Will not launch. iPhone XR/iOS 14.3. This app has not been updated for a year. It’s time for an update. Maybe they’re not updating to avoid the new privacy requirements?

I like the app, but after paying for the app I still get the ads!! It states if you purchase, the ads go away! Didn’t work out that way. No one has offered a fix and I’m still out $8. I cannot use he app without being interrupted with an add. Most frustrating.

NO ADS
It’s a great calculator but after paying for it I get these loud, obnoxious ads anyway. Hence, two stars OFF of 5.
