If you want to see the location of an object or person (like your car, dog, child) at any time and also track his movement, you will need a GPS, but it will be far more expensive and you’ll have to charge the battery often.
If you need something that will help you find an item that is usually just misplaced somewhere around you (like keys, wallet, backpack or hiding cat), Bluetooth finder is the better choice, because it’s cheaper and you will have no hassle with the battery. Because of the limited range, you won’t be able to see the live location of your item if it’s far, but you will be able to see where you last had it, so you can go back and retrieve it. And with Out of Range Alerts, Chipolo will even remind you to take your items, so you don’t leave them behind in the first place.
