Professional, Stylish, Everything.

It Couldn’t Be Better. Sleek Design, Widget, History, Themes, This App Has It All. Of Course, You Have Too Pay For Themes, But That’s Not Too Bad. And It’s Only $1.99 USD, No Silly “Free” Trial. It’s Very Well Built, I Can See All The Hard Programming, Work And Dedication That Was Poured Into This. I Am A Math Teacher, Scientist, And Part Time Programmer, So I Need Apps Like This Where My Math Isn’t Enough. As Busy As I Am, I Had Time To Leave A Review For This Wonderful App. I Never Really Do, Hence, How Good This App Is. Just One Suggestion? The Buttons Are Small, The Little Settings Button. If You Could Make Them Bigger, Please Do So In A Future Update. I Hope You, The Developer, Reads This. Please Respond And So I Can Know You’re Listening. Thank You.

Edit: So I Can Make The UI Bigger? I’ve Seen That In Settings. I Just Didn’t Know What It Would Do. Thank You For Your Response!

If you think the UI is too small, please tap and hold any area except digit screen, then pop-up menu appears, select 100% UI.

NO annoying pop-up ads!

Good free calculator with low price to upgrade to better themes, but the free themes are decent. Another good thing about this one and the very reason I uninstalled my old “free” calculator is this one doesn’t have pop-up ads. Only an ad bar at the bottom of the calculator screen. My old calculator suddenly started popping up ads right in the middle of my calculations, so it had to go. I don’t know why my iPad Air didn’t come with a calculator. Shame on Apple. I give Apple a negative rating for that for sure!

Stop ads

It would be 5 stars if there would be no ads and make a quiz so if I would say I am working on + than make a quick quiz and u have 30 hearts and ever time u make a mistake u loses a heart. ever 4 min u get a heart and the max hearts are 30 and make the quiz have 40 questions to do and the more u get right u get money not real money game money. and make a mascot and for some money u get to dress up The character in different clothes make a leader bored
And whoever has the most things solved at the end of the month
Gets an extra 500 dollars so then it would make the game more popular and people would have fun doing it. and I am 13 years old !! so if there are spelling mistakes my bad
