I bought this app to replace my iRecorder Pro app, which began having problems after the last IOS upgrade. I record astrological readings for clients, which can take over two hours, and email them the recording. The iRecorder app will break down the file into 3 or 4 sections, and I email them individually. When I used this app to record an hour and a half session, it could not email it, saying the file was too large. Given that it gives you unlimited recording time, I find that odd. Thank God I had used my iPhone with the iRecorder app as a back-up, or the entire session would have been unavailable to my client. They should tell you that you cant share large files via email, and the app doesnt break them down, as others do. A complete waste of my money, for what I need the app to do.
