First off you need the app files and obviously vont! Go onto google and type dafont.com, then search whatever font name you want, so for example love, then click download and there should be a icon at the top which is a circle with an arrow, if not it may have already downloaded onto files. If it is there click on it and click on the file name, either way you’ll end up on files.
Click the name/ file on files then there should be another icon in a box with an arrow at the bottom left, click on that and scroll down until you see vont. Click on vont then it will be on there!
I then delete the files off of files to save storage!
