Fast crash fix but hate it took negative reviews to get it


I hadn't realized how much I rely on EZPDF Reader until an update made the search feature unusable. Considering that I use this app for cross stitching and reading symbols from PDF charts, no search meant it was totally useless. Restoring various older versions didn't help and emailing customer service was just a waste a time, but apparently, a negative review goes a long way because we literally had a patch within a couple of days and the cross stitch community is happy again! I did find a replacement app if this happens again, but I do love EZPDF Reader and I hope it doesn't, so I'll continue to plug it to all my stitchy friends (that is unless we're forced to endure another lost stitching weekend).

Great for my needs


I use ezPDF for my cross stitch charts. It's one of the very few that find all instances of a symbol using search. I can also use the highlight function to color in the stitches completed in various colors. Thank you for quick fix to the text search issue!



After an update, in which I and many others experienced the loss of an ESSENTIAL aspect of functionality, the developers managed to role out a new update within a few days (maybe less than that, not sure) to fix the problem. Thank you so much!!
