Stop guessing. Start planning. See your dream tank before you buy. Ever walked into a fish store, fallen in love with a 125-gallon reef setup, then realized you have no idea if it’ll actually fit between your couch and that lamp your partner insists on keeping? We’ve all been there. Time to end the “measure twice, buy once, return it anyway” cycle. Aquarium Plan lets you design custom aquariums and visualize them in your actual space using augmented reality, no water damage, no arguing with store return policies. DESIGN YOUR PERFECT TANK Build it your way with pro-level customization: • Custom Dimensions: Rimless perfection from nano cubes to room dividers (we support your poor life choices) • Overflow Boxes: Center back, corner, full ghost overflow—dial in that reef-ready plumbing like a boss • Substrate Colors: Natural sand, black sand, planted soil, or that coral sand you swore would raise pH “just a little” • Lighting: Pendant or strip LEDs with blue/white ratio control. Even has night mode for coral viewing after dark • Equipment: Place powerheads and gyres exactly where you want them (chaotic flow pattern not included) • Aquascaping: Procedurally generated rock formations with realistic caves and porous structure • Livestock: Watch chromis damsels school around your rockwork (more fish coming soon, maybe corals too?) SEE IT IN YOUR SPACE (THE MAGIC PART) Use AR to place your design in your living room, bedroom, or that weird corner of the office your boss doesn’t know about yet. Walk around it. Check clearances. Make sure it doesn’t block the TV during football season (critical). See if your stand actually fits under that low ceiling. Confirm the overflow won’t smack into the wall. Visualize whether “just a little bigger” is actually going to work, or if your partner will stage an intervention. SAVE YOUR DESIGNS Create multiple designs and name them things like “The One I Can Actually Afford” and “The One I’ll Buy When My Tax Return Comes In.” Compare them side-by-side in 3D carousel cards. Show your family. Get buy-in before you’re knee-deep in silicone and regret. BUILT BY A FELLOW AQUARIST I’ve been in the hobby for over 20 years, and before this app, I used cardboard, tape, and Photoshop mockups to plan my dream tanks. It worked… eventually. But it took hours, never felt true-to-scale, and didn’t stop me from buying tanks that barely fit. So I built Aquarium Plan AR, because I needed it as much as you do. REALISTIC EXPECTATIONS AR is powerful, but not magic. Aquarium Plan AR works best in rooms with good lighting and clear textures—avoid glare or shiny floors. Move your camera around slowly to let it find surfaces and scale accurately. You might need to try a couple placements to get it perfect (kind of like aquascaping itself). CONTINUOUSLY IMPROVING Like your reef, this app keeps growing. Every update adds new realism, customization, and smoother AR performance based on user feedback. You build better aquariums; I build a better app. WHO THIS IS FOR • First-time aquarists trying to figure out what “display tank dimensions” actually means • Seasoned reefers planning their next upgrade (we see you eyeing that 300-gallon peninsula) • Anyone who’s ever bought furniture online and had it arrive three sizes larger than the photos suggested • People with spatial reasoning skills equivalent to a blind cave fish Look, we get it. Buying an aquarium is expensive. Moving an aquarium is more expensive. Realizing it doesn’t fit after you’ve already filled it? That’s a story you’ll be telling at club meetings for years. Try before you buy. Design before you regret. Plan before you panic. Download Aquarium Plan AR and see your future tank in stunning augmented reality. Your back, your wallet, and your relationships will thank you. For details regarding your privacy, see our privacy policy: http://aquariumapps.com/apps/aquarium-planner-ar/privacy-policy.html

Verdict

The call

The clearest difference is price: Caesar at Free against Aquarium Planner AR's $1.99. Caesar also leads on update cadence (every 2 weeks vs every 44 months) and iOS requirement (15.0 vs 17.5).
