There are too many ads, and don't say it supports the free version. You could have a basic free version and a paid complex calculator. Having your temporary clients watch an ad to open the app, then once opened, having to watch another ad to use it. Charge for all the extras, not a basic calculator. Most annoying app I've ever used. News flash, nobody ever buys anything off those useless ads. All they accomplish is you losing customers or potential customers.

Do not install this app. It is not the default calculator you're accustomed to. It's full of ads and after five different screens and six different ads, I still didn't get the actual calculator. I force stopped the app, left this review, and will uninstall it next. Do not install. If I could leave a zero star review, I would have.

This app is basically an add spamming app. I innocently downloaded this assuming it would be a normal calculator app. But JEEZ! it won't let you do anything without watching 4-5 ads first! For what? To use a damn calculator??

Hi, sorry for your bad experience. Our app is free, so we really have to involve some ads to help maintain our team and keep providing top-class services. All these ads can be closed and we will also consider a less disturbing way to display these ads in future versions. We would appreciate your understanding. Best regards.😊
