SenseGiz Find is Bluetooth tag which can be used to prevent losing or misplacing objects like keys, bags, pets, laptops, phones etc. The tag stays connected with your phone and sounds an alarm once you go away from the phone. The Find also comes with a feature to share your belongings with your friends/family, wherein suppose you have a common set of keys between you and your spouse. You could share via the app and both of you could track where the keys are at any point of time.
The plus point with SenseGiz is they are ready to ship anywhere in the world which is not the point with most other campaigns who ship only to US customers. Also, as seen from the campaign page their iOS and Android apps are already available for download on the respective stores.
You could check the campaign yourself on Kickstarter:
