The magical algorithms running the Twist app take into account traffic, different modes of transportation and your own habits when estimating your time of arrival. If you’re running late, Twist will text pre-determined contacts and let them know. You’ll never have to text while driving to get somewhere again. When you’re stuck on the train, as soon as the phone catches some WiFi, the app will let your friends know how much longer they have to wait for you. Pre-set appointments and dates on your phone — even if you’re simply commuting home or meeting friends after work — and let your loved ones know when you’ll get there. Twist, using your phone’s GPS capabilities, will text designated phone contacts when you leave and what time you’re set to arrive. Read the full story at Mashable.
