1. 3/5Calculator won’t 0 correctly.

   After iOS update 18, I started to have issues with my calculator not resetting to 0 after closing it. I would simply just passing it off as just remembering my last calculation like how safari remembers your tabs you didn’t close after closing safari and reopening it. This simply wasn’t the case, as I tried to set it to 0 prior to closing it, and it reset to the most recent calculation even after zeroing it and closing it. I do like the latest updates this has though and hopefully it can bring some Samsung users to the Apple platform. The only feature I wish Apple kept was the all clear button, instead of just flat out replacing it with the backspace button (Yes, I like the backspace button too and I think it’s a pretty good feature, but I just wish Apple kept the all clear button with it. Apple, if you’re reading this, please fix the calculator. I don’t want my calculations still appearing. I’m not sure if this is only I that gets this, but please fix it, it’s getting pretty annoying.

2. 2/5It is borderline simple and im using it for high school education 🤦‍♂️

   It is way too simple and simple in a way that makes the more complex functions confusing. The calculator is good at doing simple tasks for everyday life so i can’t complain too hard. However when doing algebra equations it is just way too simple, I can’t see what i recently inputted and honestly if you put numbers too quick sometimes they wont register(?) that part really annoys me because it often makes my calculations wrong and im confused why. Its pretty annoying, putting the wrong makes you restart. Someone mentioned “thats just laziness” but i don’t think you understand just how complex these personal finance algebraic equations get, sometimes im not aware until after i do the equation and having to put THIS MANY NUMBERS BACK IN CAREFULLY, is just annoying. I do like that the review that person left was nice, basically saying “cut them some slack” and i really do get that but it’s kinda not the point of honest reviews, this calculator isn’t good for anything more complex then % and negatives. Even putting in negative numbers tweaks out sometimes. Wouldn’t recommend for school, work or anything you have to be accurate and careful in. Good for calculating tips and dividing restaurant prices between friends. Thats it.

3. 5/5This is great!

   Everyone is saying bad things about this app like if you type one wrong number then you must restart the entire problem which isn’t even a big deal just get over it. This is a great app and has a lot of different options to do an equation with and all everyone is talking about are the flaws. I understand that it’s the point about reviewing so that they can fix it but no one actually appreciates how good of a job this app does. Whenever me or my sister needs to do homework we use this since regular calculators don’t have as many buttons or options to use. This is a great way to figure out problems both basic and advanced. Most calculators don’t have these options so if you don’t like the app then just stick with that. Also not to mention that on iPad you can change the colors and background of the screen. This is such a great way of doing math even if it’s advanced and like the other review says, Apple works hard to get us apps we could use every day but all we are doing is hating on it. Please just get over it. That’s all I have to say. Thank you

4. 5/5Why all the hate?

   This is honestly a really good calculator app! I use it all the time for homework, because all you have to do is pull out your phone or device! It has tons of different functions, like squares, cubes, or square roots, which are really helpful to have in certain areas of math! And ok, ok! We all get it! I understand that like many calculators, it can be difficult and frustrating to have to restart a problem so many times after entering a wrong number…but come on! It’s not that big of a deal! It’s one more minute of your day, and you’ll be ok! Anyway, automatically having this app on your Apple device is very helpful and useful, so please consider using it because it has all of the functions that we need, so please don’t give it so much hate for just that one inconvenience! If you got this far, thank you so much for reading and please give this app a chance! And thank you Apple for making this amazing calculator app it is really helpful to me and others I’m sure! 🥳👏🥳🥳👏👏

5. 3/5Math Notes & Conversion

   As a highway engineer in the US, I will often use my iPad Notes app for quick notes, calculations, sketches, AND stoichiometry. Sometimes I need to perform calculations with rates that have odd units of measure. For instance, an Area in SY, a thickness in inches and a rate in LB which is then converted to TON for payment. What I can’t do right now is complete all of those calcs in Notes or Math Notes. I can’t even adequately perform the stoichiometry to convert the units. If I provide standard units and it’s capable of producing a result in the correct base units, I need to be able to tap the result and pick the proper output units. I also need to be able to set units preferences so that if I place a value, it’s not continuously suggesting metric unit conversions. I know people rail against Imperial Units, but I don’t make the rules—I need to design and report values in Imperial and therefore need to be able to set those preferences.
