I’ve been there! My backup phone is pretty old, and newer apps used to crash constantly. Then I came across
master-league.com and found a section about compatibility. They tested apps on older Android versions too. I picked one of their lightweight recommendations, and it’s been great — small app size, no freezing, and still full of features. If you’re using an older device, definitely read their compatibility guide first. It saved me a ton of time trying random apps that didn’t work.
