Good app, but startup is slow.

This is an absolutely fabulous calculator app. I use it in RPN mode and I love it. My calculator used to be an HP 48G, but I switched to this for the quick stuff, as I was using my pc for the complexer things anyway.

There is one gripe I have, and that is the slow startup since some months now (don't know which version it started). I mean, I have this app for the quick stuff, but when it takes 20 seconds to start up, it's not quick anymore, is it?

Opening the app when it was recently used is quick though, but it's still annoying.

It definitely shouldn't take 20 seconds on any device, something is wrong. Does it still take that long after a restart of the device? Let me know at if you are still having problems.

Nice calc, just 1! con

Ver nice calc, it can be matched with a non free calc. But there is one thing to improve. There should be one extra row to see what is bin typed. This can actually also be done in the same. Hope to see this improvent soon.
