Following a recommendation from another thread, I switched to CallWave. It's free. One thing I like is it leaves out all of the uh-huh, bye-bye, take care, etc. that people naturally say but you don't want to read. No resident app, but all voicemail comes in email or SMS. It's also a lot faster than SimulScribe.
