Calc Reviews

This calculator was great besides the fact that it would cancel my music every time I wanted to do a simple calculation . But now with hideous update It’s too much .

Been using this calculator for years. Simple, done the trick and could see your working. But the update has overly complicated things. Can you make a toggle to go back to original? Or simple calculator instead of part scientific functions therefore button could be bigger?!?

This has been my favorite calculator app for YEARS. Why did you change the layout and colors? If you’re going to give us color options, please include the previous style!!!!

I used to love Calc. But now it defaults to the top of the tape. So you have to scroll way down to see the answer to your problem. Also you used to be able to clear the tape but no more. Please fix.

Sometime in the last couple of versions, a change was made to open Calc to the top-most (oldest) calcuation. Was this change intentional? Because it doesn’t make sense that I would care more about the oldest recorded calculation than the most recent. Now every time I re-open Calc , even if I enter a new calculation and hit ’=‘, I have to manually scroll all the way to the bottom to see my answer! This makes no sense. Please restore the old behavior, showing the most recent calculation at the outset.

Thank you.

I, too, have used Calc from the get go & have generally embraced the updates until now. I enjoyed
the ability to toggle between the classic/simplified view to the more complicated functions if need be — now, it’s a nightmare to use. There’s way too much going on the screen, which is only made worse by the nightmare color scheme. Then there’s the keyboard sounds you cannot opt out of using (all of my other keyboards are silent for a reason). Please give your users an easy way to make changes to the look/sound of Calc.

I have yet to find a very good iPhone scientific calculator that has everything I want. But this is the
one I settled on after trying out about 15 of them. It does everything, shows you what you're doing on the screen,
you can move up and down to see what has gone past, etc. Could be smarter about when to use exponential notation,
but hey I can figure that out with a little work.

I needed a this app with tape and this works great. I really like that you can enter parentheses for longer equations. My one gripe is that, once you quit Calc , when you launch it again, the tape is scrolled up and you have to manually scroll down to see where you left off. Seems it should show the most recent calculations on launch.

free, simple, has tape, no ads, color options, looks great on a big ipad. Apps this useful are generous and rare in 2025. thank you!

I’ve been using Calc for years. It’s been great but the update added key click sounds that couldn’t be turned off. The developer quickly fixed this and other complaints and it’s back to being a really great app.

This has replaced the default calculator on my home screen.

I was worries the update would have ads or something but it is a great update to my favorite little calculator app.

The history ticker an parentheses being on the main default screen is great. The answer “ans” button lets you start your next calculation with the result of your last calculation and pressing again cycles to previous answers.

How do you change the color of the themes

This was one of the first apps I ever installed on my iPhone 3G so many years ago when Calc Store was a brand new thing. I’m so happy to see it continued to be developed. Thanks for the theme support and especially the themed icons.

The support for a large “tape” area, parentheses(!), and the “ans” key (which quickly and easily inserts the answer to the previous calculation into your current calculation) make it far superior to all the other iOS calculator apps I’ve tried over the years — and I’ve tried a bunch!

This is how a true mobile calculator should be. The graphics may not be as flashy as the other options offered by the appstore, but it being a simple, no-frills calculator that incorporates the tape feature and scientific functions makes this the perfect iphone calculator in my book. Unlike the others, Calc's parenthesis function is visually-present on the lcd as you type it as well.

Update: after almost a year of using this over the default calculator, i must say that it is absolutely perfect. being able to see you past computations proved to be it's most powerful feature. and, as always, the visually-present parenthesis function in the equation is always a treat which is terribly lacking in the default calculator app as well as other much more expensive this app apps. Calc has worked flawlessly through all my firmware upgrades up to the present. for a free app that does everything the default calculator does not, Calc sure does the job perfectly.

Display is far to bright for those of us with vision issues. I believe Apple realized this in their design work on their own calculator. I believe many iphone app developers have caught on to this as well. Many apps are quite comfortable to use in low light situations, and even while studying in bed. If a user has vision issues like I do than Calc probably hurts their eyes. Of course we can change the brightness settings, but for one app is not preferred. A landscape mode would be welcomed also. But as many have said I have a number of calculators, but this is the first one I hit every time. Just wish it didn't hurt my eyes so much. Almost forgot to mention my gratitude at this being a free application. Like everyone else, I'm more than willing to pay for said improvements.

I have been using this this app since it was first released on Calc store. I replaced the Calculator app that comes with the iPhone with this one. I have gotten used to using large screen graphing calculators that show you a "tape" over the years and I have to have that feature in any calculator that I use. This is the only one I found that had it on the iPhone and its free (don't know why)! Get it now I bet you won't be able to go back to the old one.

Caculating scenarios for customers and moving up and down tape for history of entries is great. Recalling last calculation is handy, however allowing direct entry into a calculation would be better than having to delete back to the number or function to change. Recall of last answer very helpful too! Extremely useful application that replaced the included application.

1) It's great the way "ans" scrolls back through previous answers. Why not make "ret" do the same (rather than just the last expression).

2) Why not allow the user to move the cursor back through the expression to edit rather than having to delete to move back. As per editing email text etc.

Otherwise, really good!

So glad to see a this app (and free) that has the % on the front and even has a bigger keypad than regular Touch this app. Standard this app on Touch has a % but have to turn it each time to put it into landscape mode and becomes annoying when need to use quickly. This is a Perfect this app and will use this from now on. Thank you for making this free. Good Work Mike!!

Calc is exactly what I was looking for. The interface for entering expressions is nearly identical to the TI-8X graphing calculators (I.E. Entering expressions in their natural form, "ANS" button to reuse previous answer in new expression, a button for re-entering the previous expression, and a long record of previous calculations). Well done!

P.S. I would pay a dollar or two if the design were spruced up a bit.
