My examples: Sky Map - Point your phone at the sky and it will show you the names of the stars, planets and other celestial objects that you can see.
Sound Meter - uses your built-in microphone to measure sound volume in decibels
Chwazi Finger Chooser - Random Finger Chooser (before anyone asks it helps me to decide random stuff with the kids, like who takes the first turn in any game)
It's under 200 lines of JS, not available on the Webstore and not complicated (or even well-written) at all, but it's a nice feeling to use a little piece of software I wrote that's purely customised to my specific use case(s).
Not sure what you're using this for, or which exact app it is, but I use the app put out by the National Institute for Occupational Safety and Health (NIOSH) for this, NIOSH Sound Level Meter[1].
I use Network Ping Lite[2] often to just check if the network I'm on is stable/up.

I essentially keep an Arch and Windows 10 boot disc on me at all times.
You can also create blank images and it'll act as a flash drive.

Libretube - YouTube without ads, trackers or an account.
- Spectroid: A spectrum analyzer to help me identify "that annoying sound I hear" or "what's wrong with the sound in this place?" I'm not good at ignoring sound, but it helps me when I understand something about it, like "oh, that's a 10 khz harmonic" still annoying but slightly less.

Privacy.com (app) : Let's you spin up temporary credit card numbers when purchasing things online.

Probably others but I don't even know if these are "special". Just some of my first downloads on a new phone.
I've been journaling with it for two years now nearly every day and it's 100% wonderful. At the end of each year I order a physical copy of the journal for my personal archive. Highly recommend.

I bought it when my Apple watch didn't yet have a sleep tracker and have used it for the last 2 years. Good one! Has helped me understand what works for me and what doesn't. I use the iOS app for analysis.
A sample of my findings :
1. I sleep very well when I have done some hatha yoga exercises + eating early
2. I sleep pretty well when I eat early and eat mostly salads
3. Beer ruins my sleep (no surprise, really!)
4. Cheesy/foods heavy in spices make my sleep bad and my energy levels in the morning low
