Use to love this app, after the last updates it is very slow to open. It is a calculator for goodness sake. It use to open immediately like all the other calculator apps out there. But no, they had to make a worse. Do you know the saying, if it ain't broken don't try to fix it. So disappointed.

Worse app .It takes 10 to 12 second to open . And above that ad comes first. I m uninstalling. Calculator is a app which open in a second. I think there r 100's of calculator apps which r better then this app with no ads.

I know that you need ads to earn money, but sorry, it takes about 10 sec to load application on OnePlus3 and it opens chrome with ads. Ridiculous.

D70%
by D####:

It takes like 10 seconds to load now, it's almost unusable. There is better ways to implement ads, and you chose the worst one possible.

by D####:

It takes 3 seconds to load now...and sometimes when I am in a hurry I get first an add- I understand adds, but don't delay the access to the app itself. Uninstall

D70%
by D####:

I understand ads are needed​ to pay for it. Ads are everywhere and we can't escape them. If I was always in that big a hurry, I'd buy a pocket calculator. It works, that's what counts to me.
