Maybe you remember what was that app's wallet address? If you do, try to check it with
any block exploring site. blockchain.info etc. There you may find why its taking so long to process this TX. I bet it was low fee...
If what poptok suspects is right, it could also mean that your fees were so low that the network didn't accept them. The transaction couldve been reversed and you with your bitcoin in that old wallet which you no longer have access to.
