What is the Android Version you are running on the phone. (Go to Settings > About Phone) to see Android Version.
Clubster recently updated the Clubster platform with new features that are not compatible with older Android mobile phones, running Android Version 4 and earlier.
Most apps do not support mobile devices running Android Version 4 or earlier. Even Android does not support Version 4.
If you are on an older Android phone running Android Version 4, you will not be able to access the Clubster app using this device. You can always access your Clubster account on your desktop computer by going to www.clubster.com and logging into your account.
We are sorry for the inconvenience. You may want to consider upgrading to a newer Android phone, which will help you use many more apps and their features.
