Paid for upgrade but not working
I paid for the app to remove the ads, but the only way to access the paid version of the app is to open it, wait for the ad to finish, go to the settings, click the button that says Buy-upgrade to ad-free version, which opens it in the App Store, then shows me the option to open the app. When I open that it opens a new window, so I now have two different versions in separate windows from the same app on the App Store. It’s annoying and frustrating to pay for something that doesn’t work.
Ads
Way too many ads that interrupt your work and the only way to regain the app is to close and restart. Any calculations you’ve been working on are lost. Dumb app if you ask me
Surprised by the Ad.
After I gave the calculator 5 stars, I got a surprise ad. It changed the calculator to a video. I had no idea how long it would last or that it was even an ad.
Calculator functions very well. To find square root you push the square root button first and then the number.
Nice app
It’s useful. I hope it was more scientific.
Rabia
Mujhe pyaar hua tha
why do you have to hit equal key after every action???
why are there so few calculations where you can presd 3 times 3 plus 6 divided by 5 and get 3 for an answer
this is not one
most give 10.2 as an answer
Like home.
95% identical to the calculator face I used for 4 years of tech school and college. For me this is a no brainer. Well done.
It’s Rediculous
Who would pay for such basic “technology”?.
