Double Bass Apps for recording on a smartphone

[dbassnut]

Hi guys,

I'd like some advice on what would be a good app to get for recording my practice sessions in MP3 format on a smartphone (Sony Xperia L).
There are a ton of recording apps out there but I'd prefer your opinion instead.
There is no sound recorder app on my phone as it has not been released by Sony yet.
Thanks,

Just managed to get the sound recorder with the latest update but I'm still looking for something better. Any advise?
