Weenect (XS)
You can set how often the location is updated, from once every five minutes to every ten seconds. You can shorten the interval when your cat is lost. If your cat is nearby but not visible, you can make the tracker play a sound signal via the app; at night, the built-in flashlight helps. Everything also happens through the app here, the tracker doesn’t have a screen.
Kippy (EVO)
Kippy works with direct location determination via GPS, Glonass, wifi, and Bluetooth, visible as soon as you open the app. Kippy doesn’t have a Lost Mode with a visible message on the tracker itself: the tracker doesn’t have a screen, so the finder of your cat depends on the app. However, you can set zones for a notification as soon as your cat leaves a familiar area.
So the main difference is: with Tractive, Weenect, and Kippy, the finder of your cat needs to know the app or be able to reach you, while the CatX immediately shows the answer on the collar itself.
