What's a good Android app for sending photos and messages to my grandchildren without all the fuss?

Well, after a bit of trial and error, I've found WhatsApp to be wonderfully organized for keeping in touch with my grandchildren. It’s delightfully intuitive, even for someone like me who didn’t grow up with all this technology! The photos I send are clear, and I can even leave little voice messages – much easier than typing on this small screen, I must say. I've even figured out how to create groups, so I can send a message to all the grandchildren at once! It's like having a card catalog of my family right in my pocket. Who knew my phone could do this? I must say, for a retired librarian, I'm quite pleased with my newfound tech skills. It makes information management so much easier, even if it's just keeping up with the little ones and their school plays.
