Hi, I'm the dev 👋
I think we all know the ocean is in trouble. But it's hard to know what to do about it when you're just one diver.
Here's what I've realised though — we're not just one diver. There are thousands of us out there, hitting the same sites, season after season, watching the same reefs. That's an incredible amount of collective knowledge that right now just... disappears after every dive.
Surface Interval is my attempt to change that. Log your dives, spot your species, and together we start building a real picture of what's happening beneath the surface — site by site, year by year.
I built this app because I love diving. But I keep building it because I think we can actually make a difference.
If you're reading this, I'd love for you to be part of it.
Want to dive in early?
Surface Interval is in closed beta on Android. Drop me an email and I'll add you to the testing list.
Public release coming once we have enough testers 🤞
