I'm sure there are countless apps out there that are incredibly cool, interesting, or useful, but just haven't hit the mainstream yet. Maybe it's a productivity tool that's boosted your efficiency, a unique game that's kept you entertained for hours, or a niche app that's catered perfectly to one of your hobbies or interests.
What are some Android hidden gem apps that you've used a bunch or think it's really cool/interesting/useful?
Please share your recommendations, and if possible, a brief description of what the app does and why you find it so valuable.
Looking forward to uncovering some hidden treasures in the Android app world. Thanks in advance for your suggestions!

Like its hard to find a note app that doesn't try to get me to sign up and subscribe to features. I just want to take notes like I'm a PI investigating people at my local mall
You can also use Syncthing to keep your notes synchronized across multiple devices. Syncthing is an app that does just that (keep files synchronized in the background).
