Is there an app that will let me record voice in a loop for 2 hours.

[Android Central Question]

I work in a field of business where critical evidence and infortmation can be lost if my voice recorder is not recording. I wonder if there is an app that records all mic input and stores it for 1 to 2 hours and then once it jas recorded for the time period chosen deletes the previous data. But records in a continuous time loop.
