Alternative App for iFont?

I have an iPad Air 2, my very first iPad I got for a great deal. I had no idea it was such an old model when I bought it. I’m a creator using apps like procreate (the entire reason I bought an iPad to begin with), Cricut Design Space, Canva, etc. Well fonts are a big part of my designs and the cookie cutter fonts that come pre installed on devices doesn’t cut it for me. I prefer to purchase fonts from Etsy and then upload them. This works fine on procreate but not on Design Space which that’s where I really need it! I hear iFont is the perfect app for this, problem is my iPad is ‘too old’ for it. iFont requires iOS 17 and my iPad won’t go any higher than 15.8.2 😢😢

Does anyone have a solution or suggestion? Are there any apps that are comparable to iFont that are compatible with my device? My iPad runs pretty great considering how ancient it is and I don’t have the money to get a newer model anytime soon. There has got to be some kind of work around for this, right?
