Among paid and free scan apps, this one is EASILY the best of the lot.
◄ Comparison ► Like many, Ive wasted too much time downloading and deleting every UPC/QR scanner available. Among the free and paid, this is the best one yet.
◄ Function ► Using it at home, in stores, with Wi-Fi or cell data, its the only one that functions properly, swiftly providing accurate details. To date, this is the only scanning app that WORKS WHEN I NEED IT. I generally only require pertinent data, limited to the basics, or "brass tacks." It delivers that and more. I couldnt be happier with its PERFORMANCE & RELIABILITY.
