OneCalc+ All-in-one Calculator App Reviews

Can’t find the square root button, where is it please?

Lot’s of functions - easy to use abd nice features such as the history of calculations. I do have a couple of reservations: the systematic underlying of every number and symbol on the calculator is very annoying abd distracting but it cannot be removed. So the minus sign, for example, looks like an equal sign because it is underlined. The other reservation us the lack of choice of a “skin”. It shouldn’t be hard to add a few.

All in one calculator is my favorite.

Ok but not great

I’m going on 4 years using this calculator. The extra functionality for figuring temperatures, distance, etc makes it a an exceptionally useful app.

Could be better if it had percent increase or decrease calculation. That would make it worth 5 stars for me.

I think the underline is unnecessary on every button,hope they can be removed in future

I like this app. I purchased the lifetime license to remove the ads. It is superior to the stock calculator in most ways. My only request is for the developer to add a swap button on the currency calculator so we can easily swap between currencies for example USD > DOP and the swap button to quickly switch to DOP > USD

Great calculator. Modestly priced paid app. This app is what I would have expected as a default app on my iPhone. Sadly, Apple failed me there. But this app is great. No ads. No tracking. (Again, talking about the paid version.) Just a good calculator app. Highly recommend.

I use this app a lot and would have rated 5 stars if the favorites list was sortable. Would be helpful to enable alpha sorting at a minimum. Would be even more helpful to have a manual ordering option.

Great easy to use calculator. With lots of bonus calculations you get included. No brainer don’t have to remember formulas, you get the answer you need with just inputting values. I like its simplicity and any highly recommend for quick one offs. Soulver is also good for more involved tallies with persistence

It is of great use

Please add ability to swap regular calculator for the app! Need to be able to quickly access the app from a locked phone. Current behavior requires fully unlocking to use the app.

I do a LOT of financial calculations every day and this app is unquestionably the best thing I’ve ever had on my iPhone. It does all kinds of functions which is super helpful but the best feature is the history function. The history of previous calculations has saved me a bunch of times. This is a great app.

I bought the premium, but it still asks me to watch ads and has annoying music as well. How can I stop getting offer to watch ads and music? Thanks

Defaults to metric so has be be changed to miles and pounds every use. Should be able to set your own default!

I like the calculator well enough. But I paid so I wouldn’t see ads and they still appear. That why I gave a low rating. Update: the problem here was on my end. The plus version had downloaded to my phone but I just didn’t see it.

Over the years I have downloaded and tried MANY calculator apps. Occasionally I would aquire a favorite of sorts, but none that would keep me from looking at more. I found this one a couple of years ago and I have never downloaded another. This one is extremely complete and I most highly recommend it.

If developer can remove the underline, it will be better. The underlines are unnecessary for the symbols and really affect the user experience.

Hi you have an excellent app, and this is my primary calculator. Is it possible to get a widget for it so that I can calculate without going to the app. Thanks

Please remove the underlining on every key. It only shows on iPad but not on the iPhone app. I don’t see the purpose of underlining every digit on the keys. It makes the app very ugly. I will give 5 stars when it is done. Other than that the app is wonderful. Thank you dev, for responding, I am very satisfied. Problem solved. Like I promised you deserve 5 stars.

Mostly as advertised, memory functions a bit bugged though. If you press a number, hit m+, then mr, then m- or m+ again the displayed value is not subtracted/added from memory.

I really like this app, but find myself going to other calculators because this one lacks a couple of features that I always use: - inversion (yeah, there’s an x^y button, but an additional x^-1 button would be useful) - EE to standard notation (a button to go back and forth between engineering and standard notation would be very useful)

It’s a great Calculator. Thank’s Alan-

Great calculator. Only miss the Bluetooth keypad support. Why in More it is possible.

My old calculator had that option on top where you can set the tax rate for your State up and then add it automatically to the total. This one makes you use an option to figure it out Other than that it is worth it for paid version so far! 👌🏼

I’d expect this to work with Apple’s premier keyboard, but it does not. No number keys seem to be supported. Disappointed and want my money back.

i learned all this stuff to do myself and then got this

Excelente con muchas opciones muy útiles

The app does not have a - / + button, as it does in all other apps

Tip and split feature should allow to enter the tax so you don’t tip on taxes. But allowing the taxes to be included when bill is split with other people.

I have the ad free version, yet I still see ads and have to watch them to get 7 days of ad free…. Why?
