OrbMi

OrbMi provides messaging for voice and video messages to your friends and family, with the added value of location-based delivery. With OrbMi, you can send someone a message for when they get home, and they actually get it when they get home. You can add any number of locations, and you can add as many of your friends as you want into your “Orbit”. Send messages whenever YOU want, and they get them in the location where they can actually listen to your voice and watch your video.

Video and voice are not convenient to receive unless you are in a place where you can actually watch and listen. With OrbMi, it is always the right time to send a message and you will never wake someone up or reach them when they are out and busy. Messages are delivered only when they are back in one of the locations they have set up to receive those messages. You can send yourself reminders to your own locations too, which is great for to-do reminders and other location-based notifications.

Try it for yourself and see how you can use OrbMi to communicate with voice and video better and more conveniently with the people you want to hear from and see more often.
