Traveling around the world can be lots of fun. Having to deal with surprise baggage fees is not though. A smart scale like Weigh-to-Fly can help you avoid unnecessary airline fees. This device sends real time weight updates to your phone as you pack. It also helps you stay close to your bag with a proximity alarm.
Weigh-to-Fly has a telescopic frame, so it can slide and lock to fit any case you bring. It has sensors in its 4 corners. The companion app runs on iOS and Android devices. It is expected to have an Apple Watch as well. More information is available on Kickstarter.
