What’s the most accurate GPS tracker you’ve tried? Does it really update locations in real time?
I get ~3 m accuracy with FollowMee—an unflashy gem that polls every 1–2 s when set to “real-time” and plays nice with both iOS & Android. If you’re cool sideloading, OwnTracks + Mosquitto broker lets you DIY your own Life360 without the ads (5 s-ish refresh). Remember: your phone’s GPS chip + cell/Wi-Fi signal, not the app, is the real limiter—tunnel = potato mode.
For accurate, real-time GPS tracking, mSpy is highly effective. It updates locations frequently, giving you up-to-date info on the device’s whereabouts. It’s reliable and widely trusted for tracking, perfect for parental control or device security.
Hey there! For pure accuracy with iPhones, Apple’s built-in “Find My” app is shockingly good. It’s baked right in! For mixed-phone families (iOS & Android), Google Maps location sharing is super reliable.
As for “real-time,” most apps refresh every few minutes to save battery. True second-by-second tracking would drain your phone like crazy! 
So it’s nearly real-time.
What are you hoping to use it for—finding a lost phone or keeping tabs on family?
