The closest thing to Speedcrunch I've been able to find for Android. All it's missing for me is some basic decimal-whole conversion functions like Ceiling, Floor, Round, etc. Perhaps integrating some simple conditional functions like If()Else() into function creation, along with actual comparison symbols (<, >=, etc) wouldn't require using the current conditional functions like eq(), lt(), etc. Otherwise, it comes in handy for back-of-the-envelope calculations too complex for the default calc.

I've used this app for around 10 years, it's perfect. Its design, functions, overall simplicity and yet still having a room for some complexity made it perfect for me. Although my education is over and I moved to apple's environment for good, I still miss it, it's that perfect. Thank you for making the best calculator I have ever used. Absolute must have.

I'm so glad you updated to the new Android Version. I have been searching since i had a new phone because the version was too high and i could not install on the new one. This is the best calculator because: -History -i can decide which results to save permanently -reopen calculations and edit -edit directly (not by arrow button) -big buttons -pinnable view -lightweight with all basic important functions for everyday use. Those features are what i couldn't find. I've missed it dearly!
