Findertag
Read full descriptionHide full description
FinderTag is an affordable and tiny device that works with an iPhone app to help you locate things. Attach it to your keys and never lose them again. Put one on your car in case it's ever stolen. Put it on your dog's leash just in case. You can activate a FinderTag to ring so you can find it by sound. If your item ever goes missing, you can mark it as a lost item, this puts all the other FinderTag apps on the lookout for it. If any user gets in range of your item there phone will discreetly communicate with our system and you will be sent a message with the location of your items whereabouts. Put one on your car so you don't have to remember where you parked. If you have a FinderTag on your keyring you can activate your phone to alert if it's in range so you never need to look for your phone again. It's time to stop wasting time looking for things. FinderTag turns on GPS in the background in order to locate missing items and then turns it off after getting the location. Continued use of GPS running in the background can dramatically decrease battery life.

Verdict
The clearest difference is price: Findertag at Free against Sensor Logs's $0.99. Findertag also leads on update cadence (every 4 months vs every 88 months) and iOS requirement (7.1 vs 16.0). On ads, in-app purchases and device support there is nothing between them.
