There right

This is the best free app.

Can’t play music

Despite not having any sound come from the banner ads, the app will stop any music you are listening to every 5-10 seconds. Very irritating. Otherwise works pretty well

Awesome Calculator.

Very nicely done and appreciate the overall native feel to the interface. Only small detail is the icon of the app doesn't look as polished as everything else. It'd be great to have the possibility to drop the name in the icon.

Quite an excellent and robust tool

Quite an excellent Andrew barstool shuffle do use a Lotta good functions.

if you’re a 83/84 person, just but it!

I’ve been searching for years to have a calculator that felt like home sitting in pocket. It feels so polished and has so many features.

Incredibly helpful!

Helped and is exactly what I need!

Garbage

I paid for the app and ever since then it malfunctions. The app shuts off when I press enter.

The App Crashes

The app was crashing and I thought it was because it wanted me to upgrade. I purchased the upgrade and it is continuing to crash. It wont solve a single math problem before it crashes.

Good except for 2 things

Doesn’t let you see anything from complex infinity answers, and won’t let you simplify certain answers.

Perfecta para mis trabajos

La verdad muy específica trae todo y fácil de usa
