Para mi gusto, la mejor calculadora de la App Store, ojalá en el futuro se pueda contar con más idiomas, de todas formas, un App muy intuitiva.

Very good - great for the Watch

I got this app as it works on the Apple Watch without an iPhone present. The Watch app is nicely presented and has a very handy and easy to use conversion function. Recommend.

great and powerful

All buttons become ilegible from time to time, unsorted, and overlapped...

This calculator is wonderful, but this interface mistakes make it unusable.

If this happen to you, hold any button and reset all icons.

Try switching off the "Tap and hold to edit layout" option in the Advanced section of the settings. That should prevent any accidental edits.
