Update broke widgets

I absolutely love this app because I can leave a calculation on a widget. Say for example I can add my grocery bill up and see the total right on my screen. That was until a recent update. Now the widget shows nothing. That kind of breaks the app for me.

Fantastic, full-featured, and free

Really love this calculator. It does everything I want, especially the option to do per unit price calculations easily.

If I could add one option to the wishlist of updates it would be a cleaner icon or even better choice of icons to select from.
