That bus stop scare had our whole block talking too, my wife and I spent like a week researching every app we could find after another parent mentioned seeing someone suspicious hanging around the corner. Tried a couple free ones first and they were basically useless, either constant crashes or features locked behind paywalls everywhere. Ended up going with uMobix phone monitoring app after a few neighbors vouched for it, said it actually worked without feeling like some cheap spy tool. Been using it for a few months now and honestly it’s one of those things you wish you set up before the scare happened, not after.
