I thought this app was very simple and easy to use. When you first open up Snaptell, you get three options: scan a barcode, upload a picture from your photo album, or take a picture with the app.
When you select 'scan a barcode', Snaptell enables the camera on your phone. On the screen, you'll see a opaque white rectangle with a red bar running horizaintally through the middle. What you have to do is find the barcode on the produt you wish to look up, position the barcode in the designated area, and take the picture. When you have positioned the barcide in the right area, the red bar wil tunr green.
Once you've correctly taken a picture of the barcode, Snaptell will take a few minutes to search the web for this product. Snaptell will come back to you and display the lowest and highest prices, customer reviews, and locations where it is sold.
The 'take a picture with the app' option works like the barcode option, although I would recommend scanning the barcode if you are able to. Taking the picture with the app, then having Snaptell search the web for the product, takes a while, and often gives you results or a similar looking product.
