I just started using AwardWallet, and paid to upgrade...the upgrade is good because you won't get full information on all your accounts if you don't upgrade. For example, they'll only give you expiration dates on 3 or 4 accounts, and I think they hide some of the details.

You can test drive yourself...just set up and account and start adding rewards programs. You can see what information they hide (info is replaced with Upgrade link), and if it matters to you what they hide, make a small donation to view that information
