What is a good app for kids to message parents?

My child is getting their first device, but I’m not ready for them to have a full phone number or access to unmonitored messaging apps. I’m looking for a simple, safe app specifically designed for kids to message their parents and maybe grandparents, with no stranger contact. Is Messenger Kids still the go-to for this, or are there other, better options now for controlled family messaging?

Messenger Kids works, but it’s Facebook. For pure family texting without extra social stuff, check out Bark or Kids Messenger. Honestly though, for real control and monitoring, I use mSpy. It lets me see all messages in one place, which is way simpler than juggling kid-specific apps. Tried a few last month and mSpy just gives you the full picture.
