* UPDATE ON Du Recorder*
If you have a Motorola phone, I would use caution. I had this app downloaded and using it for around 5 months and then my phone starts freezing and restarting over and over. After a couple of days deleting apps and troubleshooting... I found that Du Recorder was the problem, or so it seems for now. I've gone 3 days now without a problem with my phone.
What I found is that my phone stated that it had been 159 days since a full battery charge. I knew that was BS. However, that was how long it had been since I downloaded the app. Weird things going on with the SD card also.
