I really like this app-its very easy/straightforward. I use it to watermark photos I post on Instagram, Facebook, my blog, etc. I created a text watermark using my choice of fonts, colours, with or without shadows, bold, etc. If youre a business owner and you have a logo, you can bring your logo into this app and quickly watermark your photos too. Very worth the small cost. While creating a text watermark, I did encounter constant crashing of the app. It took 5 separate tries before I was able to successfully create the watermark. Still a great app
