Now I am sure there are far better word art apps out there but I don’t own them. However, I do own WordFoto. It has been sitting on my iPad unused and uninstalled for years. To my great surprise it actually worked as it must be several years or more since I last opened up the app especially when you go to WordFoto website, yes it still exists, you find this disclaimer:
WordFoto has been discontinued
Thank you for your support of WordFoto. We have decided to discontinue this app. We appreciate your understanding.

So it is at least 6 years since I last used this app but in truth it has been much longer since I used it in anger and yet it still works on iPad OS 17. It really must be a very simple app indeed. Of course getting the images out of the app is another matter. But I managed it. Will I use it? Not at all sure but it is just nice to have an app that runs even when it has been discontinued.
