The XY4+ is an update to XY3, the previous version of the tracker manufactured by The Findables Company. The previous model was reviewed on The Gadgeteer about a year ago at this link. The XY4+ claims to provide a larger battery, increased range and a louder speaker than the previous model. The XY4+ also integrates with IFTTT and Zapier so that you can automate actions based on triggers and even have the finder beep based on other automation triggers.
It seems that The Findables Co. is doing everything in its power to demonstrate superiority to its competition (Tile, TrackR, Chipolo, etc.). It seems that environmental footprint is also an area that the manufacturer is focusing on. They have a very small retail box. However, the product is packaged in non-recyclable foam.
The tracker is made from ASB plastic and is snapped together from two halves. The assembly is quite durable, even though it is designed to be opened. The XY4+ is designed to fit onto a key chain or maybe in a pocket or a bag. It makes sense for it to have a smooth profile, but while the top of the tracker is somewhat curved the bottom is completely flat and has some point edges. I would expect the tracker to be more clam shell shaped. The top features a triangular shaped button with the XY logo on it.
The XY4+ can be accessed by iPhone and Android devices but the last known location can also be seen on any web browser at my.xyfindit.com. The web browser will show a map of all of your item locations.
