Recordings are saved directly to the user's MicroSD card. This means your system's internal memory won't be bogged down and your recording times will still be maintained for hours on end if necessary.
The application doesn't just record messages as I mentioned above; it can send messages as well. You just need to sign up for a free Gmail account then choose to send the message and it will send it as an attachment via your Gmail account. It's also simple to configure; you just need to enter in your Gmail login information and you're ready to go.
Another unique option is the ability to set when you want a recording to begin. For example, let's say I want a recording to start at 10am. I simply enter in 10am, add a title for the recording if I choose to use a title, and enter the duration of the recording, for example, 60 minutes. When I hit "Set," the program will begin recording at that time based on my phone's own internal clock. I can also hit "Cancel" to stop that operation. I personally fail to see the use for this part of the Voice Recorder application, but I'm sure you can find some way to use this option.
