OneCalc Reviews

8/2(2+2) = 1 It gives me 16 for an answer. The order of operations tells me parentheses first, then multiplication, then division. It should give me an answer of 1. It gives me the wrong answer.

I’ve read the developer’s reply and found their reasoning flawed. I can’t see people paying for a subscription to OneCalc. When they learn how to do math I may reinstall their app but for now I am looking for another.

I want to sum durations in mixed units of measure. Specifically, how long it takes to complete a list of tasks. I’ve timed each task and have results in minutes and seconds. The only time tasks you have are durations between two time points. This is quite a gap in your claim that your app calculates everything — there’s another app that adds times. Says to me there’s a need for this type of calculation. Perhaps add the word “nearly” — then it would be truthful. As it is, right now you’re over promising and under delivering.

Overall a decent calculator but the “Date duration” calculator on iPhone is incorrect (1 day short). Odd because the same company’s website is correct. I performed the same calculation on a few different calculators and all come up with 104 days (NOT including the last day) between March 9, 2023 and June 21, 2023.

I can understand that it’s free and that the developer needs to make money, but don’t have an ad flash in front of my face while I’m typing numbers in. Make it an ad banner or something on the bottom. I uninstalled it because it was getting so ridiculous.

Been using frequently for a year now. Great multi tool calculator. It’s got different conversion calculators for anything you need. Love the calculator can go from simple to scientific easily. The favorites is helpful for the tools you use most. The one thing I’d like to see is for the conversions to have more than 2 slots, I’d like to be able to type in one unit and have it show multiple conversions of my choice. I think this is a simple add and delete put to the user.

Easy to use. Got this for the history feature. But still showed me ads when I upgraded to no ads and paid for the upgrade w no ads. So one star reduction.

I used another Calculator app but u had to pay for almost everything and there was way less features. This really is useful and helps me do a lot of every day things.

After one week, when I tried to use this application, it played a repetitive sound like “a cola …. “. I didn’t understood well so I uninstalled it and installed again!

This is a sleek modern layout of keys and display. Besides the calculator there are all sorts of measurements available for absolutely free. Watch a 60 second video and there are no more ads for an entire week.

This Calculator has the basic functions which includes the memory plus and minus which I really like but it also has pretty much anything else you may need.

I love that this has backspace and shows your whole equation so you can know you typed the numbers right!

It is very simple yet has advanced features without making you rotate your phone sideways

I like the clever converters and solvers that let you fill in the numbers you know in order to calculate the others. Press More to see them

I am impressed by the items that we can use in our daily life, which have been bundled into OneCalc, except for some UI changes that may spruce up OneCalc ... it’s otherwise really good.

It took me waaayyy too many downloads to find a scientific calculator with no ad banners lol. OneCalc checked all the boxes !

This is definitely the best; love that you can change the appearance of the calculator to make it look like your typical Apple calc / between two other aesthetically pleasing options :)

Plus the ability to earn ad free for 7 days at a time is wayyy more user friendly & I don’t mind it at all.

I’m also beyond glad that it supports split screen mode !

Thank you for making a fully functional & user friendly calculator for iPads :)

I tried them all and this is definitely the best. If you use it you will see how great it is from the accurate performance and key response to the clear layout to the extra features, like the additional 00, and 000 keys to the ability to add vibrations and sounds.

With husband being retired from construction he sometimes helps friends.
I am retired from being a Tax Commissioner and owning a private accounting business.
Many times I will receive a call for help.
OneCalc allows both my husband and I to complete tasks required to assist others.
Perfect and the ads are minimal. Thank you!

I am a student at Hillside Elementary school eagle point Oregon.

Fifth grade Mr. Carpenter’s class is hard math homework. OneCalc really helped me and you can’t even watch ads which are actually some of them are really fun to do like put like puzzles and when you watch the ads to get seven days of free day ads, which is really really easy to do.❤️❤️❤️➖✖️➕➗🟰 so fun.!!!

This calculator app (free from Appl store) can do all the things I needed. Be it simple or complex math computations.
The best is: by just one click, it will show you all the history steps for the data and calculation results, very handy to verify what being entered. Plus it has many functions and settings to satisfy just about most you can think of.

Squid, I totally agree with you and was surprised that there wasn’t more reviews about this calculator maybe people are concerned that if they comment it will change the status of it’s availability or something uhmmmm, I’m not sure I’m just saying! lol. However my experience with this calculator has been very good. Thank you for taking the stress out of calculating. It’s great

I’ve never written a review for an app before but this one deserves it! I only use the basic functions but I needed the memory +/- functions on it. I also really like the “tape” function to look at past calculations. The annoying video ads are infrequent so I don’t feel like I’m being interrupted ever couple key strokes. I tried several free calculator apps and I can say this is by far my favorite!

Best calculator app ever, bar none. It literally has everything I could possibly need and want in a calculator, plus it’s totally simplified. I am thoroughly impressed, seriously. The free version is just as good as the paid but since it’s so amazing I decided to support these guys, so worth it.
