I'm launching BeFree here on Wednesday: you talk, it sorts your messy day into tasks, reminders, events, lists, and notes. No deciding where things go.
Before I do: what's the most chaotic thing you'd actually say to a brain-dump app? Genuinely curious what people would throw at it.
Speak one messy brain-dump and BeFree sorts it into the right place: tasks, reminders, calendar events, grocery, and notes. No forms, no deciding where things go. Capture offline; syncs across iPhone and web. Free forever; Pro is $49.99/yr or $6.99/mo, 7-day trial.
