What’s nice about a smart watch is that it’s basically a dumb phone that’s hard to lose. Great for kids.
It’s an enabler! Smartwatch is better than dumb phone in nearly every way. Can phone? Check. Has GPS? Check. Can route public transport? Check. No tiktok? Check! Good battery life. No check :(
I work around that last one with a keychain battery charger.
This is not a substitute for teaching your kid what to do when lost (or watch is lost or nicked), but it gives them tremendous freedom. My son can navigate the world on his own now, all thanks to a bit of techno-magic on his wrist.
