Glympse allows you to share your location privately by text, email or publicly on Facebook & Twitter. It uses GPS to pinpoint your location and tracks your movements accurately. The unique feature of Glympse is that you have to initiate the broadcast yourself, and furthermore you can be selective about who gets to know about it. You’re also able to set a time limit on the availability of your location. This means that Glympse isn’t constantly broadcasting your position throughout the day without your knowledge. It allows you to be entirely in control over who sees where you are.
How it works:
Pick numbers or emails of people with whom you want to share your location. Decide for how long you want to send out your location (15 minutes, 2 hours, indefinitely). Click the send button and they are sent a link to the Glympse site that will keep them updated on your location. Once you’ve sent out the links you can still go back and edit how long you want to be tracked and even cancel the invitation altogether.
- User can share location with someone who doesn’t have a phone (they can open the link via email)
- Customize everything about your location sharing (even pick a picture to display of yourself)
- Add a personal message to the invitation while sending the invitation.
- Add or subtract time as to how long location can be viewed.
- Updates constantly so user’s exact location is broadcasted.
- It even announces how fast user is travelling (if user is in a car).
