This has been the only calculator I've used for 11 years now. It's one of the very few apps I have which have lasted this long while still being updated. From new phones and tablets, it's always in the bottom left corner of my home page. As for reliability, on the off chance the app malfunctions I would assume it was a problem with my phone, not the app. Bottom line is it won't replace a graphing calculator, but it definitely does not disappoint. Buy it.

I last reviewed this 11 years ago! And it's just as great today as it was back then. A great look and feel with plenty of functionality including RPN modes! The conversion feature is super useful, too. If you need a solid, flexible, and reliable calculator, this is it. Thank you, devs, for keeping this current. It's become an old friend.

I just now purchased the upgrade after using the free version for close to a decade -- and I use it every day. I didn't even care about or pay $3.49 for what the upgrade offers, but rather felt the usefulness I've received from the free version all these years finally deserved some remuneration. My experience (or, at least with the free version) is that it's a simple, standard calculator, but it works *really well*. Brava Quartic. Looking forward to seeing what the upgrade can do.
