That's ten year old Android. There are very few apps that are still going to work on that. The already installed, offline, no ads, no subscription apps that are already on it will continue to work just about forever, but "connected" things (Including Google Play) are dead or maybe partly alive but badly broken. Which makes it hard to come by those apps that still work if you don't already have them. The software isn't able to do modern things, and the hardware is not able to run software that's updated enough to do the modern internet, so nobody is writing things for them.
You can navigate to Google Play, but it's broken.
You can't use it for a Chromecast or smart TV remote any more.
You can't stream music to it for any length of time, it'll crash.
You can't "internet" with it any more, as it's security protocols are too far out of date.
You can only barely "internet" with it anyhow.
Ten years ago was the days when you could buy a prepaid smart phone (a good one for the time) for 20 or 30 bucks, never hook it up, and have essentially a tiny little wifi only tablet in every room, and for every job.... I had a bunch. Well, four maybe, outside of my actual phone. My android 4 stuff held on for a very, very long time. I never owned any other variants until I went straight from that to Android 12. But it's effectively been nuked. I have ONE left that will still get Pandora, but it crashes every hour or two. Another is a dedicated alarm clock. (They're GREAT for that...) Three "phones" and a couple of tablets have been recycled, as each time the last useful app(s) sneek through my barricade and download an update, they're irrevocably broken. When they "still" have a use, they're useful. When you want to add a "new" use.... Even the old, heavy, fat tablets from ten years ago are too light and skinny to be a good doorstop. Any android that old just needs to be recycled. If you're not using it for anything else- Take it (and it's old, probably heavily degraded) lithium battery to whatever the local recycling option is and let it go....
