Painful at best…bioload add a zebra moray. Largest size is 9-10 inches. Umm my eel is more like 36 inches. I paid for it but I am not sure I am in love with it yet. The fish input leaves a lot to be desired. Coral identification, etc.. I am going to say aquarimate is still king. So far I am underwhelmed. Maybe they need a vision/news page…or and a suggestions. They need to get this UI cleaned up. Don’t know but it could be amazing. Just not yet. ### 2/5 — Promising AI platform💪 *2025-07-16* I was really excited to check this out after seeing Hilary’s video—it’s a great concept with a lot of Ai potential. I currently use Aquarimate along with a complete Neptune Apex setup to monitor my reef tank, so I’m always open to trying new tools that might enhance or simplify the process. Unfortunately, I ran into technical issues right away. During registration, I kept getting “upstream request timeout” errors. After a couple of tries, I thought I might’ve made it through—only to hit the same wall when trying to request a password reset. That completely froze the app and caused it to crash & close. Giving it 2 stars because the Ai idea is promising but as is, it’s clearly work in progress. Depending on the 💰and how stable things are after the initial rush, I may give it another shot. ### 1/5 — Cash grab *2025-01-27* Downloaded bc reef builders gave a shout out and uploaded all my testing info and now to do anything else in the app i have to pay a subscription. Also very buggy and lacking features which would make this worth anything. Save the money and just ask Chatgpt the same questions. Or use any other FREE system to track testing data. Sad to see something so shamelessly trying to make money off hobbyists with what could really help beginners. **Developer response:** Thank you for trying ReefAbility and sharing your feedback. Our app offers extensive features beyond basic parameter tracking, including AI-powered pest/coral identification, predictive analytics, and personalized insights based on your tank's data.

After trying to open it again it repeatedly seems the graphics are corrupt. It flashes many colors and images just shake on the screen. Still persists even after multiple closures and restarts of the app. I was hopeful, seemed like a nice easy to use setup. **Developer response:** We apologize for the display issues you've experienced and appreciate you bringing this to our attention.

Tried uninstall/reinstall but issue persists ### 1/5 — Don’t waste your money *2026-05-31, version 1.1.104* What a waste of money. Reviews in you tube sing this apps praises but pointless. The addition of equipment does not contain anywhere near a full list, inc Red Sea gear. You can find what the AI does by quick searches and there are plenty of free nutrient recording apps. Please don’t make the same mistake I did and pay for this! ### 1/5 — Not Ready *2026-01-27* Despite several ICP test results uploaded and weeks worth of testing data, all my pumps, lighting data, the AI still can’t give me insights on my tank. ### 1/5 — Remind me again why I’m paying for this? *2026-01-12* Paying a premium for a buggy app. To log in I need to log in close the app and reopen. To input any parameter nothing happens doesn’t save to register. Useless ### 1/5 — Fighting *2025-12-11, version 1.1.73 3* If you like fighting an app and it telling you you are wrong all the time and it not letting you change things you know are wrong. And you have all the time in the world . This is the app for you. ### 1/5 — Needs lots of work *2025-09-23* Not Worth the Subscription The AI assistant takes forever to respond, and the lighting section is very limited — mainly geared toward LEDs. There’s no proper support for T5 users, no bulb selection, and no option to set the number of bulbs. The identity is subpar tried using it for algae issue and got several different answers on what it was from 3 different photos of the same algae, Uploading a screenshot of parameters doesn’t actually update them. The home page feels cluttered and busy, and navigation is sluggish overall. It also doesn’t work with Apple’s Magic Keyboard — touch only — which makes it even more frustrating to use. I’ll be sticking with ChatGPT instead. Glad I only paid for a one-month subscription. ### 1/5 — Useless *2025-07-27* Couldn’t even get the app to run. Clicked on any setting and blank screen. Would need to close and open the app again. ### 1/5 — Slow *2025-07-16* Extremely slow app. It won’t event process my tank details. ### 1/5 — Find another Reef App *2025-03-21* I tried the app based on the shoutout from Reefbuilders. Unfortunately the app has a terrible UX with many clicks needs to get to what you need. Unintuitive design and graphics. There is a paywall in front of everything. The prices are WAY too expensive and offer no monthly tier or free trial. And when you abandon the app, the developer emails you offering 70% off. I am sticking with Aquarimate for the fixed $10 app cost. Thank you! ### 1/5 — Rubbish *2025-02-26, version 1.1.17* This app is absolutely rubbish spent ages trying to get in to it kept asking me to change my information like I was lying about it wast time I want get not even worth a star ## Most praised reviews (10 highest-rated) ### 5/5 — Best reef keeping app ever *2025-12-27* I’m genuinely amazed by Reefability, especially the Reefer AI. Being able to review my ICP test history and get clear, actionable insights has completely changed how I manage my tank. I can even ask specific questions based on long-term trends, which makes the recommendations feel personalized and trustworthy. Since using the chemistry forecast, I’ve been able to prevent several issues before they impacted my corals and it shows. My corals are healthier, more stable, and looking better than ever. This app has become an essential part of my reef keeping routine. Thank you for building such a powerful and thoughtful tool for the reefing community. ### 5/5 — Essential reef keeping app *2025-12-24* Reefability has become an essential part of how I manage my reef tank, the insights are clear,the AI tools are incredibly helpful and the app helps me make better decisions with confidence. My tank has never been more stable. Highly recommended for any reefer. The ICP tests insights have been a game changer, clear trends, smart recommendations and healthier corals as a result. Thank you please keep adding more great tools in the app. ### 5/5 — Genius! *2025-02-03* Finally, an app that truly understands reef keeping! Being able to snap a photo of any coral or suspicious hitchhiker and get instant AI identification has saved me countless hours of forum searching. The genius feature of importing my entire Apex history through photos turned months of data into actionable insights instantly. Love how it predicts my parameter trends and alerts me before problems develop - caught a potential phosphate spike early thanks to the forecasting. The support team replies within hours when I have questions. Even helped me optimize my dosing schedule based on my specific tank's trends. If you're serious about reef keeping, this app is absolutely essential. Best investment I've made for my tank management! ### 5/5 — Game Changing App *2025-02-02* Mind blown by how Reefability scanned my entire Apex Fusion history through photos and converted it into actionable insights! No more manual data entry - just took pics of my display, and boom - all my historical parameters were there with trend analysis. But the real MVP is the AI pest identifier. Found some weird critters in my tank, took a quick photo, and instantly got an ID with treatment options. This saved me hours of forum searching and guesswork. Used to spend ages trying to ID hitchhikers and pests on reef forums - now it's literally seconds. The AI even pointed out a potentially harmful nudibranch I hadn't noticed in one of my coral photos. Best reef keeping innovation I've seen in years! ### 5/5 — Amazing App *2025-02-02* Next-level nutrient management! Absolutely blown away by ReefAbility's nutrient tracking and forecasting! The app accurately predicts my nitrate and phosphate trends, helping me maintain perfect balance before issues arise. It's like having a crystal ball for my reef tank. The graphs showing how my nutrients will trend over the next weeks have helped me optimize my feeding and water change schedule. Combined with the AI assistant that knows my tank's history, it's made reef keeping so much more predictable If you're serious about reef keeping, this app is a must-have tool! ### 4/5 — Great Approach *2025-07-03* Great Approach. App is clearly still an early production release with many warts, but the general concept is wonderful and much better than other apps. The developers are very responsive to addressing issues as uncovered. The AI driven advice is pretty consistent with what you’d find researching, that AI elements work quite well. ### 3/5 — Not user friendly *2026-03-29* Too much going on. Hard to track parameters. Ai is terribly slow and honestly… not very helpful. Definitely need to work out some kinks ### 3/5 — Great Approach *2025-08-03* Great Approach.

I paid for it but I am not sure I am in love with it yet. The fish input leaves a lot to be desired. Coral identification, etc. Just needs refinement. I am going to say aquarimate is still king. Lots of work but lots of potential. So far I am underwhelmed. Maybe they need a vision/news page…or and a suggestions. Don’t know but it could be amazing. Just not yet. ### 2/5 — Waste of money for iPhone users. *2026-08-05* Honestly. This app is becoming more of a headache. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
