Simply a Great Calculator!

I am a wordy reviewer so I am also infrequent. However, I just had to say how great a find thiis calculator is.

I was unhappy when my old iPad calculator app became a liability on iOS 10. I looked for a usable replacement--large, user-friendly without so many functions that I would need another degree just to be able to use it. If it would give me a record of the numbers and totals, I would definitely pay for it. After downloading a number of freebies, I was beginning to think that there wasn't a way to not have all of the extra bells and whistles. (I also found one that made me think of killing myself if I couldn't find a way to avoid touching an ad--not cool on a calculator, even for a try-out. I couldn't even find where the in-app purchase place was to buy myself out of ad hell!)

I was about to despair when 7th Gear's Calculator! showed up in my wanderings thru the App Store (no, it didn't show up when I did a search under "calculator"). This calculator was perfect, giving the user the option to choose either way. It even has a customizable widget!. I really, really like how the notes keep track of all of the calculations, not just the numbers, and they can be sent to my printer. Furthermore, there are several customizations to the look of the background that I found to be well worth the full price (built-in, or more personalized--deep purple leather with dark stitching, be still my heart).

This is the calculator that should have been included with the iPad

I've tried many calculator apps and this is the only one that seems to have been designed by people who need to use a calculator app regularly. It does the math most people need (this is not a substitute for a full scientific graphing calculator), and has useful extras like notes and the log (both of which can be printed, copied, or emailed right from the app).

Most importantly, the interface is uncluttered and makes great use of space on the iPad. I don't want a calculator that fills the entire screen, either with absurdly large buttons or an excessive number of buttons. This app gets it just right...a good sized calculator (in either standard or scientific mode) that still leaves room for the notes and log.

Do yourself a favor and stop wasting time trying out other calculator apps. Spend a buck and get this app, you won't regret it.

Shows equation

I love this calculator because when you press = you still see your equation. So you can double check right away that you entered the correct amounts. I bought another calculator app and as soon as you pressed = only the answer remained. I hate that. This was the one feature I wanted to subtract my check book. You can also see a history of your equations in the " notes " section. I do wish the numbers in the Notes section were a bit larger. Also it's fun to customize the background colors. I'm very happy with it and uninstalled the other calculator app, so I'm out $2.99.
