What's a good Android app for, like, keeping tabs on my heart health from my phone? Especially one that's easy to use after a long shift?

Seriously, Kardia absolutely slaps. I found this cool feature by accident when I was trying to figure out why I felt kinda weird after a crazy shift. Turns out, this app lets you take a legit EKG with your phone. Like, you just hold your fingers on the sensors, and boom, heart data! It's saved my shift a couple of times, letting me know when I should probably chill out or see a doc. Plus, it keeps a history, so you can see trends and stuff. It's like having a digital barback, always looking out for you. And the best part? It's super simple to use, even when you're brain-dead tired at 2 AM. No complicated menus or anything. Just fire it up and get your heart rate. Definitely recommend if you're looking to keep an eye on things without a ton of hassle.
