Mappos Bluetooth Key Finder (Green) with new feature: Movement Alert. No subscription required. Works with iOS/Siri.

Photo shows the scale if you have one of these trolley join key ringsMy problem with it is that it disconnects itself. I have to keep starting it. It isn't a problem if you lose your key, you can connect it through your phone, but if you lose your phone, not really!I find that every time I truly needed it it wasn't useful. I removed any battery saving option on my phone to keep it alive, but I'm seeing other apps remain alive, why is thus the only one shutting off?Hope developers look into this, because the concept is very useful

Bought this for my mum after she lost her keys 3 times in one week. So rather than have her committed I got her this little gadget which she made use of a few days after receiving it. I'll be getting all the old ones in my family one for their birthdays as it's really useful.

This was easy to setup once the app was downloaded. The option to buy in different colours is great and helps you to easily distinguish bunches of keys (if using more than 1). So far I have only had to use it to find my phone in the house and it works very well for that purpose. So far I have not lost my keys but I know I have more of a chance in finding them now this key finder is attached to it. It was one of the cheapest on the market and so far it's worked as expected.

Got this for my dad, its great it works well. But when he tries to find his phone it doesnt seem to work unless the phone is unlocked:(

This was the perfect answer for my husband who can never remember where he’s put his keys. It was easy to set up the app to ping his keys. Also handy for when he can’t find his phone and he can ping the Mappos key finder to track his phone down.

Far cheaper than others I looked at. I bought it for my son who is always mislaying his wallet in the house, it works brilliantly every time.

Neat little gadget and the ability to act as a remote for the iPhone camera is a nice bonus

Excellent value key finder / pet tag easy to use app and track / sound finder
