It's been my No 1 used app for years UPDATE Still using after 12 years It is FAULTLESS

I use this app everyday. It's fantastic for watermarking my art prints & eBay sales inventory photographs/autographed photos against theft.
UPDATE 2025 -,This App has never once broken in 12+ years & it is still my go to for fonts & watermarking. Thank you so much for keeping it going so long, it is much appreciated.
