Firstly download the app Widgetsmith, open the app and choose the size, there is small, medium & large – tap on the one you prefer.
You can add widgets with time, date, calendar, reminders, etc.
For example let’s chose the calendar and customize it. You can change the background color, the font, add borders, etc..
Also you can add a widget with an image:
Scroll a little bit down -> tap on photo -> selected photo -> choose your image and save it.
Once you have saved the widget, go to your Home Screen, touch and hold an empty area until your apps jiggle, it will appear the “+” sign tap on it and scroll down, tap on widgetsmith, tap the size you’ve chosen before and tap on Add Widget.
And you’re done!!
