Invite iOS

Appuous project. Worked on this for about a year. Interesting project, but unfortunately took too long to ship, and the shipped version was far from the original (and IMHO, better) vision.

Originally, connect w/ Facebook or Google Plus, and grant cal access. Add cals by iCloud auth, Google, etc. Backend tracked blocks in which one is and isn't busy. Intended for large social groups/orgs, where most members could easily have the app, and a single (though potentially rotating) event organizer would invite group members.

Select contacts, and then on "Set Date & Time," you're shown which times are best for which attendees. It automatically suggests the date/time most convenient for all invitees.

Not shown: if date/time is set first, "Invite Contacts" displays a full contacts list, but makes clear those who can and cannot attend the selected date/time.

Storyboard with full screens attached. Props to @Ramotion for the hardware illustration.
