Hey , I do like the looks of this one . Great job! Only thing odd is that I can't find the widget to download
Seller 2016.02.11
Dear teresamurphy5555, Thank you for the comments. :) There is no widget that you should download. If you press long on the main screen of your smartphone, widget setting menu will show up.(on the bottom) Then, you can find our widget on the widget list and set that. There are some widget that pro-version use only. But basically there are many widgets on our app. So we hope you can find a widget that useful to you. Have a nice day. Best regards,
