I use this key ring app to hold digital copies of store loyalty cards, gym membership cards, etc. I recently went to install on my new Lumia 521 and found it had been pulled from the store. When I asked about it, as you can see in the attached tweet, they said they had to pull it because of the number of bugs they were experiencing.

Please consider contacting the developers (@keyringapp on twitter) and ask them to bring this app back to the windows phone platform.
