I am totally blind as well. Both
$1 and
$1 are very accessible with VoiceOver. I've used
$1 the most lately. Even if you have functional hearing, having a transcript you can have have read to you by VoiceOver later is very helpful.
$1 gives you 40 minutes of recording time per session for free while
$1 has reduced their free users to 30 minutes at a time,. You have to stop and then start a new session / recording when the timer runs out. If you just want audio, an app like Voice Recorder or iTalk might be what you want without the time limits.
