The app and concept is great, their website works better. After using this app for a couple.days after changing notification settings the app stops responding and is blank with a spinning wheel. 3rd time I've had to reinstall the app to get it to work after having it for a while. Stupid addicting to buy stuff off this app and not all sellers are super honest. The tracking on the purchases don't show you what you actually purchased... Just that something was purchased.
