Swiss Army knife of calculators


I didn’t think it was possible to love a calculator, but I find myself absolutely loving this app! The “paper tape” history is handy. So is bookmarking certain numbers and equations. One small bug, the history doesn’t always show on my iPad in portrait mode. I have to rotate to landscape.

Overall, it’s a great app. There’s probably way more features here than I’d ever use, but the ones I’ve used so far are worth it alone. This saves me a ton of time.

Small learning curve but much better than anything else


I have a few feature requests. Any chance of getting a copy to clipboard option when pushing on the app icon? Also an easier way of pressing AC. Functions such as sin(x) and a^b, and could we customize which of these is in our keyboard for faster access?



I’ve just got it so far it’s been extremely better than the other calculator I’ve been using and it was truly worth the price $1.99 you can’t get a cup of coffee for that price I’ll write a better review for it once ive had the chance to use it more it seems like it is truly amazing 😉
