Pros and cons of The Calculator app for iPhone and iPad

The Calculator app good for

Sometimes i need to calcuate angles for wood working. Some features with tan, sin, cos to remember me easily how to calculate these woulb be very helpful and timesaving. :)
Great calculator. Big numbers, smooth operation. Gets the math right, too.
It also correctly answers 6922251 x 8; so, pretty good, for a calculator
This calculator is really good. Thank you for making this good calculator.
Its a adds, it subtracts and it works ;)
I have used this app. for a long time. Suits my needs to a T!

Some bad moments

Le temps d attente est beaucoup trop long lors de louverture. Rgds
since update to ios10 The Calculator widget no longer has multiply and divide! pls fix
Before this current update they had multiply and divide in the Notification Center widget. I can add and subtract in my head for most numbers I use in my daily life, but multiplying and diving is more complicated. Like why the hell would you replace two vital functions with an "open in app" button? If I wanted the full app, I would open the full app. I just want a quick multiplication/division
Loading time is too long for the app to open up and widget of it doesnt contain the multiplier button and the The divide button
Please give me back my old calculator app with no ads and fast startup time. For my phone this new version is too slow and irritating. They want money to get rid of the ads. Thats not updating. Thats downgrading in my opinion.
I would rate a huge 5 star if the app would stop asking to rate it! So when it did ask, I wrote this review. Just STOP asking.
