I tried so many apps today, some free some paid and none of them actually did anything. A few were creating a modified version of my site and I had to go in and adjust everything. But this app is actually just one button. I am soo impressed. Welldone guys. It feels so much quicker to use the site.

My store was just loading pretty slow and I double checked Page Speed Optimizer and opened it on my app., section since I changed to a new theme and anyway, it definitely loaded much faster instantly. Thank you!
