Please answer the following question: On a scale of 1-5 (with 1 being least favorable and 5 being most favorable), how would you rate this review? "Functional The app works for what you need and that is all. Interface could use an update. Focus times can be slow though it will usually find and scan the code within a few seconds. Install if you need the functionality. Probably the best scanner until Google (hopefully) develop a stock scanner for Android."
