I made and operate a small app called [FishHarmony](https://www.fishharmony.com/). It's a simple app for iPhone that tells you what fish species (fresh or salt, I offer both) are compatible with fish of different species! So if you want to see if Tetras get along with Rasboras, for example, you can check my app/website! I've done no marketing and get something ~200 active users per month and 1K+ downloads lifetime. Not much, but still cool that people are using it!
I pay about 7/month for a Heroku instance and the stupid $99 a year for the App Store. Working on some freemium apps that will hopefully offset those costs.
