iOS/Android/WP8: Previously mentioned personal assistant Indigo organises your appointments, sets reminders and alerts, and supports voice commands. The app keeps everything in sync across all of your devices, and now that includes iOS.
When we discussed Indigo before, we noted how well it synced with Google Calendar, how easy it was to set up appointments and reminders, update Twitter or Facebook by voice, and display business listings in Yelp or Google+ and show you the location via Google Street View.
The newest version of the app brings all of those features to the iPhone and iPad. The service has also been updated with an improved engine, so it can remember things you discussed with it in the past and carry on a back-and-forth conversation without you having to repeat commands.
