XO Gallery

Super helpful support, very flexible app settings, exactly what I was looking for. I wanted the type of UI/UX and customization options like LightGallery and others offer for the web that I had used before without the hassle of building/managing custom liquid+js+css+html+assets. After a quick tour and the first gallery working pretty quickly, I found that planning things out really helped because there are endless options/configs available and in-app CSS overrides to boot. The developer jumped online with me to solve a small issue same day which was painless and I appreciated that considering I was on a free trial. I tried a number of other apps, nothing came close - XO Gallery for the win!
