Is there an app that allows me to insert a Minecraft nameplate into a real photo?

I would like to edit a picture for a younger person.

On a picture of what was made of him in real life, his Minecraft name in the Minecraft font should be above his head as it looks in the game. How can I do that easily?

The easiest way is probably to download a Minecraft font.
Search term would be for example "Minecraft font download".

I do not know anything about mobile phone apps, but writing a text on a photo would actually have to create every photo editing app, I think.
