Setting up plans is never an easy thing when you have to wade through screens and screens of e-mails or text messages to figure out who’s in and who’s out. The planning app Klutch is designed to take the back and forth out of scheduling by making it immediate, easy and fluid so you can spend more time hanging out and less time planning to hang out. Organizers can propose a variety of plans and keep a running total of votes from other friends who download the app — and there’s a chat function, as well, just in case you want to hash out the details. The app can automatically add events to your calendar, and it even gives you the option to use the mapping app of your choice — Apple Maps or Google Maps — if you have a strong preference. Free, for iOS.
