Nice GUI, slow app

As the title suggests, the interface is pretty but the app itself is as slow as one could be afraid of. Theres a constant reload after entering more numbers. It seems like the app fetches data with every calculation instead of syncing once after program start (and maybe interval-based).

If any of the creators read this, you know what to do ;=)
