It's seriously just a mobile phone. It's incredibly slim and sleek, and at about the size of a credit card, Light Phone only receives calls and makes calls. This means no texting, emailing, (annoying) notifications, or anything else that keeps us disconnected from the real world. It simply transfers the phone calls from your smartphone to your Light Phone via companion app.
It's essentially an extender to your smartphone, so no need to feel freaked out when leaving the home with just it. You really only need a phone for phone calls, right? Not in today's world, but, hopefully if you're on a big mountain hike or adventure with a friend, the Light Phone can keep your safety and peace of mind sustained. For $100, you can get the Light Phone via Kickstarter, with 500 minutes of pre-paid talk time (which should really last you a long time).
