A while ago Katie Floyd put out a call on Twitter looking for a replacement app which can overlay contact information onto your wallpaper for iOS. I thought "I bet you can do this with Workflow", and I was right! Here's how it works.
Text: This contains your name.
Text: This contains your phone number, advice: Don't use the number of your iPhone, use that of a trusted family member or friend, or your home phone if you have one.
Text: HTML formatting of the above two items, your name is set to be smaller than the phone number as it's likely to be longer and not quite as important.
Make Rich Text from HTML: Now we make that HTML into rich Text - applying the formatting.
Make PDF: Bear with me, PDFs are great!
Convert Image: PDFs can be converted to images - voila! We now have a white image with black text.
Crop Image: Let's make this approximately the same aspect ratio as an iPhone X screen.
Resize Image: Shrink it down to be about the right size
Set Variable: Make it easy to access in a moment.
Select Photos: Choose your background.
Mask Image: Here's the magic. The mask image action is like a very smart overlay, here it will make sure the text of your name and contact number shows up on the wallpaper, and nothing else.
Quick Look: Check it for prettiness.
Share: Save it where you want!
