No, it doesn’t. One of the best things about the Unleashed is that your phone doesn’t even need to stay connected while your timelapse is running. Once you setup an interval shot/timelapse, you can leave the app, go out of range, switch your phone off etc. and the Unleashed will continue taking photos as set in the app. The smarts are all built into the Unleashed itself. Once you’re back into range or reconnect, you will see the updated process of the timelapse in the Unleashed app.
