What's a good Android app for keeping my phone's internet connection private and secure when I'm using public Wi-Fi at the hospital or coffee shops?

Okay, so as a nurse, I'm constantly hopping onto different Wi-Fi networks, and honestly, it makes me a little nervous about security. I've been looking into VPNs, and ARAS VPN seems like a solid option. It's got a 4.2 rating, which is pretty good, and from what I've read, it's designed to be easy to use. I really need something reliable that I can just switch on and forget about, especially when I'm accessing patient records or banking info on my phone. The last thing I need is a security breach! Plus, a VPN is supposed to help keep your location private, which is a nice bonus. I'm planning to download it and give it a try – anything that makes my digital life a little more secure gets a thumbs up from me!
