I didn't need any of the pro features and the occasional "please buy pro" screen didn't pop up often enough to be annoying, but I use this app all the time and it a great calculator. The developer(s) have me a great free calculator for a couple of years without nagging me, I figured it was about time to say "thank you".

EXCEPTIONAL! Now I normally wouldn't even buy a calculator app, however, I did for one reason, to support this Dev!! Because even though there's more choices if purchased, and for a lot of ppl you might need and want that, me, just wanted a really nice, Nono glitches, NO Ads, extremely sharp looking and functional Calculator!! This is it ya'll!! Even with free version, but like I said it's so good, small size, and gorgeous, it's totally worth throwing this Dev a few bucks!

Edit: Hopefully a multi-screen option could be implemented for the announced v2, like the one found in "Multi-screen voice calculator" in the store. As well as an option to clear all multiple screens with a long press. A very well designed calc app. Glad to see it is still maintained in 2023 and hopefully beyond!
