Take the difficulty out of organizing get togethers with your friends. LockIn is a fully fledged chat application with one priority: meeting up with your friends. Whether it’s a casual get together or a full on event. LockIn lets you quickly establish the time and place, and who can make it. Then during the event, thanks to LockIn’s hassle free location sharing, how far away any late comers are.

With a full web backend you are free to invite any one with an email address, whether they have the app or not! Everyone can join.

- At a glance see who can and cannot make an event.
- Set temporary “meet here” locations at any time in any chat for quick meetups.
- Keep your privacy with automatic location sharing only just before and after an event time.
- Temporarily share your location with other chat guests for periods from 1 hour to 1 week.
- Integrates with your devices built in calendar.

Please note: Continued use of GPS running in the background can dramatically decrease battery life.

Terrific app for casual meetups and group chat

If you are trying to get a diverse group together for beers, or find your friends at an event, or set up an impromptu group chat (or all of the above at the same time), you need a tool that works on the devices the people have. With support for all popular phones, computers, and even email, this app nails it. There is not a single person I know who can't participate using LockIn.

The UI is great, too, especially on iPhone. The travel lines of each participant's location over time, superimposed on the map, is a great touch that somebody should have thought of a long time ago. It really gives you a sense of when people are actually going to arrive. The chat UI is very well thought-out, too -- but what else would you expect from the makers of Cheezy Beatz?.

All in all this is a great and truly universal app that helps make your actual offline social life as effortless as your online one.
