“It’s amazing at diagnosing illnesses in fish … Worth every penny for me.”— App Store review, April 2026
“Clean, modern aquarium tracker with powerful features … Great for both beginners and experienced hobbyists!”— App Store review, May 2026
Point the camera at a test strip, a fish, or a sick fin. AquaLens reads it — no manual color-matching, no guesswork about species.
Every scan and reading lands in your tank's journal automatically. The history builds while you just keep doing water changes.
When a trend drifts toward trouble, AquaLens flags it with what to check — while the fix is still a water change, not a loss.
That's the core loop. See everything else AquaLens does →
Every test, scan, dose, and water change becomes your tank's history — and history is what lets AquaLens warn you early. A calculator answers today's question; the app knows that your nitrate has crept up three weeks running, that this ammonia blip looks like the one before your last algae bloom, and that your reef's alkalinity drifts every time you skip a Sunday. The longer you use it, the smarter it gets about your water.
Verbatim five-star reviews from the App Store.
“I love this app! I’m new to aquascaping and have found this tool to be extremely helpful and insightful! So glad I saw this app recommended in one of my fishy FB groups. I recommend it every chance I get!”
“It’s amazing at diagnosing illnesses in fish, helpful with identifying fish and plants, amazing at predicting parameters and also been great at tracking feeding and dosing meds, fertilizer, etc. … Worth every penny for me. … as a newer tank owner it’s been invaluable.”
“Clean, modern aquarium tracker with powerful features. Love having water parameters, livestock, and maintenance logs all in one place. Great for both beginners and experienced hobbyists!”
“It’s a new app, that the owner listens to users and is making tweaks/adjustments. Simple and easy way to track the water chemistry of your tank. Health features use AI to analyze pictures of plants and fish to give a diagnosis.”
By day, I run a small, highly specialized research company — engineering proteins, building biosensors, and leading a team of research scientists at the intersection of biotech and national security. Our work is funded by the DoD and DoE, spanning everything from critical mineral recovery to field-deployable biosensing platforms.
AquaLens was born out of my own frustration. Turns out, keeping lab notes isn't that different from keeping tank notes — weighing chemicals, controlling conditions, and obsessing over parameters. I wanted a better, smarter way to log tank data, track expenses, and monitor the overall health of my ecosystems. When I couldn't find an app that did exactly what I needed, I decided to build one myself.
Because it's just me behind the screen, I rely heavily on the community. If you find a bug, have an idea for a new feature, or just want to share a picture of your setup, I'd love to hear from you. Thanks for coming along for the ride!
