Used this app for 3 weeks. I love the ease of the scanning part but a major bug happened where anything I scanned something to count inventory and it happened to be the correct amount it would zero out the inventory and it would tell shopify i had 0 when I had 24. Major major bug - contacted them about this issue, no reply. Also, the app kept freezing to the point where it was only useful if I deleted the entire app and reinstalled it on the iphone. Then it would freeze again and will not get out of the updating screen where once you save your count it never updates what you scanned and freezes. I had to delete the app and can no longer use this app. Not trustworthy to help inventory my business.
