Voice Memo Applications

[Rural]

I am due for an upgrade from my current N80. I have considered the E71 but it does not have a voice memo function which I use all the time on my N80 and on previous phones that I have had. It is great for making notes about ideas, to-do's, etc whilst driving, waking up in the middle of the night, with company, etc

Does anyone have any experience of any of the voice memo applications that are available for smart phones out there? I mean- found an app, installed it and use it trouble free daily
