Qatar Stickers Album

This app will help you collect your Qatar Album in an easy way!
Works with versions of 638 and 670 stickers.
Add or remove your stickers by any of these methods:
1) Take a photo of the back of multiple stickers and they will be registered automatically.
2) Write a list of those stickers to add or remove.
3) Look for each sticker and increase or decresase its quantity by tapping.
The app can manage repeated stickers. You may share a QR code with your friends and compare both albums. Also, choose between the matched stickers to exchange them and they will be registered automatically.
Nice interface to show your statistics. Check your progress, both, at general and country/sticker type level.
Filter the stickers that you are missing, those you only have once, or those repeated. Share them with your friends in an easy way.
Enable or disable optional stickers such as C1-C8 that could be present in some albums.
In case you lose control of your repeated stickers, remove them and add them again without affecting the rest of the album.
If you have already started, you may choose to start with the album full, and manually delete those you are missing.
Change the color of the stickers as you wish.
