What's a decent Android app for sendin' quick pics to the grandkids without all the fuss?

Look, I ain't gonna lie, I'm not big on all this newfangled social media crap. But the wife wanted me to keep in touch with the grandkids, and they're all about the Snapchat. It's actually pretty simple once you figure it out – which took me longer than I'd like to admit. The tutorial is useless, but once you figure it out, it's easy to snap a quick pic of the job site or the dog and send it over. The pictures disappear after a bit, which is fine by me – less clutter. Haven't dropped my phone yet while using it, so can't vouch for durability in that sense. Battery life on my phone is always a concern, and this thing does drain it a bit faster. Still, it gets the job done. No BS, just pictures to the grandkids. I wish it was built like a brick house, but so far it's alright.
