ReefBay

This app is exactly what the saltwater community has been missing. It feels like a true social hub for reef keepers—easy to navigate, packed with useful tools, and built around an active, knowledgeable community. You can share tank updates, buy or sell coral and equipment, track water parameters, and even create a dedicated profile for your tank. Everything is intuitive and well thought out. Whether you’re new to the hobby or a seasoned reefer, this app adds real value and makes staying organized and connected effortless

When I started my first reef tank, I got this app originally just as a calendar to track my maintenance tasks. The app is fantastic for that. But I’ve also fallen in love with the rest. It’s the only social media I’m on anymore and only brings me joy. It’s a great place to ask questions as a new reefer. It also has a market place to buy some fantastic stuff from reef venders all over. I also use its AI all the time to ask questions about my specific tank since it has my tank data. This app makes this hobby 10x more fun. Love it.

The creator is still in the works with everything on the app but so far is amazing! Has everything you could want on it. Buy. Sell. Ask. Answer. Share. Track. Tasks. Parameters. Encyclopedia. Creator monitors the app and is responsive and open to any and all suggestions. He has several things in the works to improve the app and is constantly adding features and improvements. I am hoping in the very near future I can downsize from 3+ reefing apps to this one and only!!
