Ive used Phonto as my go-to font/text app for years (along with many apps by this awesome dev).
Phonto is fast, deep, precise, and intuitive.
You can save as .PNG (lossless file format) or standard .JPG (lossy) and import fonts, too...a big plus--and the marks of a pro-featured app.
IAP/add-ons are handy and worth it (I own all except the image one).
Its also updated regularly.
Highly recommended, and kudos to youtthr!
