▸ Calculator + App Reviews

Highly recommended!!! It works on iPhone 6+ iOS 10.0.2. Many thanks!

Update: developer seems to be on a roll and has recently issued another update which has fixed the currency converter. Keep up the good work!! Have been a long time fan of this multi-function calculator for its clean interface, no ads and broad array of functions. The recent update has made it partially usable but the currency calculator still does not work. Hoping for another update soon.

After waiting years for an update, its here! Thank you so much developers. This app has it all. A selection of calculators, tip, date/time, unit conversion, financial/loans and much more. You can pay for an additional 3 optional professional features. It worth the $. Thanks again for the update.

Used this calculator every day until I upgraded to iOS 10. Now it not only doesnt work, it freezes my iPhone 6 and I have to do a hard reset to get the phone working again. Too bad. I liked this app. I wont delete it yet, in the hope that the developer issues an update. But Im not holding my breath. its been three years at least since the last one. If there is a fix, Ill update this review. UPDATE: Developers released an update that partially restores the app. It isnt quite as intuitive as before, but Im sure Ill get used to the changes. The currency converter is not working, which is too bad, as that is one of the modules I used regularly. When that is restored, Ill update a third time with 5 stars, if it is working properly. UPDATE: Currency converter is fixed. All is good. Very useful multi-function tool. Much more than a calculator. Highly recommended.

The new update does not have Maldives currency anymore!!!!

When I tried to copy expression say 255/3*2, the app exited. Pls fix asap. Thx

After the last updates I now receive annoying pop ups in the paid version trying to sell me more features and skins

Constant ads in this paid app.

the ads popup quite often i buy the periodic table,theres no atom radius data, what a pity! Can you fix this?

Great interface, need some more themes based for guys.. Steel, carbon, metal, neon.. Eliminate all the stupid ads.. Paid a lot of $$ to eliminate this.. Dont think if should pop up on phone. Keep updating for iPhone 5 larger screen.

I have a pile of great apps on my phone, but there are none that I use as much as HiCalc. Logical layout, intuitive design, and a lot of good data right at my fingertips; absolutely the most useful and used app I have on my phone.

Graphic Display not support for iPhone 5

Great to graph and do math

Hands down the best calculator app in the store. Its blows the competition away. I do with it had a true EE button, however. I use this app all the time and its basically perfect.

Best calc-huge number of options including a fabulous RPN calc. Highest rated calc available. Love it!!!!

I downloaded many calc apps, but this one is the only calc survives on my iOS devices.

This is the best calculator app Ive found so far.

Easy. One used the most out of few I tried.

Has more functions than any calculator Ive ever had! And easy to operate, too. A great app!

The UI is good, the function useful
