Constantly times out of WiFi. Just spent 2 hours getting back on after iPhone update. Baffling to me as good a company as Kessil is they let this go on. Just put a $10 k link dongle out there and put Bluetooth on the app. If that’s possible I would think so 🤷🏻‍♂️ ### 1/5 — AP9 issue *2024-09-15, version 1.11* I been using Kessil lights for about 3 years, actually with a setup of 2 of them and Im really happy, BUT this app is so useless and annoying, Have no sense there is no upgrades and Firmware changes on the lights to avoid this constant need to add the lamps every time you us the app , can someone at Kessil can explain this?? We are in 2024 ### 1/5 — Great Lights - App Crashes *2024-08-14, version 1.11* The app hasn’t been updated in 2 years? Gee, I wonder why it crashes? Maybe if I still had an iPhone 12 with iOS 12 it would work better. I go to try and schedule lunar or sunset events in my schedule and boom, the app crashes. $2100 on lights and now I guess I have to drop another $1000 for a 3rd party Apex to be able to make the lights do things that Kessil should have baked in and be the best at doing. Obviously from other reviews support is a waste of time and I found similar in my pre-purchase planning trying to obtain a DMX converter to use to control via K-link. Nope, only for commercial installs. I guess $2100 isn’t worth their care or worry. So I also bought an AI Blade and a G6 Radion on my sump. Maybe those will end up being better. Time will tell. ### 1/5 — Mediocre at best *2024-08-11, version 1.11* Extremely slow to load and connect Lost connection with the dongle. Now it’s impossible to re-connect. Layout is not user friendly. Functions are not user friendly. Difficult to understand ### 1/5 — Worst App connectitivity *2024-07-21, version 1.11* I have 2 AP9X’s with the k link cable which work absolutely flawless for the price. This app however, has great settings for control which is only useful if you can ever get them to connect or “stay connected”. I am tech savvy and have an entire smarthome setup. This app has gotten me so boiling to the point that i could toss these lights into the street and roll over them continuously with my truck. Do better Kessil ### 1/5 — Rubbish *2024-07-16* Simply rubbish !! ### 1/5 — Useless *2024-04-17, version 1.11* Constant crashes while trying a quick reload. Had to delete and reinstall app only to have it lose connection again and back to crashing while trying to reload. When this is the only way to control your lights, having an unstable app is unacceptable. ### 2/5 — Is this app still supported ? *2023-12-10, version 1.11* Time zone seems to be off. I tried to log in - no luck. I came to the App Store to see if there was a newer version. No luck. Not sure if this app is being supported at all. That said, I can still control my light but timing is off. ### 1/5 — Does Kessil use this app themselves? *2023-08-09* This app is by far the clunkiest and non-user-friendly app on my phone. Always breaks, always forgets my dongle, need to reset app far too much. How can these lights be so good but the controller is pure garbage. For lights in this price range this app should be better than AI’s light app. And it’s not. And their app has issues too. As someone else said, it feels Beta. I’d say Alpha. “Make sure light is orange” - doesn’t instruct how to make light orange. Figured it out on my own. No reliable subnet cross communication. Do better. Hire better developers. ### 1/5 — Absolute garbage *2023-06-17, version 1.11* This app is so bad that you have to factory reset it every single time you want to connect to the lights. Truly amazing that Kessil was able to create an even bigger steaming pile of garbage than Mobius. ### 1/5 — Wifi dongle stinks!! *2023-03-22, version 1.11* Can’t get it to connect some days it work other somedays it don't. ### 1/5 — Not working for me *2023-03-04, version 1.11* Can’t get logged in. Tried logging in through google 3 times. Asks me to enable local network but the setting doesn’t exist. ### 1/5 — Connectivity problems *2023-02-09, version 1.11* I am currently using an iPhone 14 and was not able to use the app to connect with a wireless router. However when on an iPhone 8 the app does work. ### 1/5 — This app is horrible *2022-11-24, version 1.11* Had this app for nearly a year have to consistently re-program the connect the lights to the system very finicky the lights are good but the app is horrible highly recommend against it ### 1/5 — Terrible App *2022-10-17, version 1.11* Don’t buy these lights if you’re hoping for an easy wifi controller with this app. Absolutely terrible app. Disconnects constantly. I’ve had this app for over a year in hopes that this would get better, but they haven’t touched it. The lights are great, but the ability to control them is unsatisfactory. ### 3/5 — Works well when it works *2022-08-10, version 1.11* Difficult to connect to and when it does connect it freaks out crashes. When it works it’s nice. ### 1/5 — Crap *2022-04-21, version 1.11* Continuing reloads every time you want to go in quick reload quick reload there’s nothing worse than fighting the same fight every day I would wait tell they get their wifi figured out ### 1/5 — Horribly disappointing *2022-04-15, version 1.11* Incredible lights that are rendered pretty much useless due to this app, unfortunately don’t waste your money on these lights until this issue is fixed ### 1/5 — Not user friendly *2022-04-11, version 1.11* App is not user friendly. My sprinkler app is easier to figure out. Takes forever to figure out how to set timing. It’s awful ## Most critical reviews (10 lowest-rated) ### 1/5 — Horrible app *2026-05-29, version 1.11* For 1500 dollars for 3 lights, I’d think that it wouldn’t take 20 minutes every time the app chooses to disconnect itself. Sometimes every 5 minutes, sometimes once an hour, sometimes every 3 days. This app is absolutely atrocious and for a premium lighting company to even associate themselves with it is disgusting. They have literally ruined the experience of owning their product products because of their lack of attention to their app. You can’t access the functionality of the lights without the app, but the app doesn’t work. This will be the last time I ever buy a Kessil product. ### 1/5 — Worst app ever written 0 stars *2025-12-30, version 1.11* I would not buy Kessil items ### 1/5 — This app makes me want to throw my lights away *2025-12-18, version 1.11* This may be one of the most frustrating apps built to configure IoT devices. ### 1/5 — Terrible app terrible customer support *2025-10-27, version 1.11* App always crashes. Lights are poorly made. I should have gone with Radions. Customer support was no help. ### 1/5 — One massive headache *2025-10-18, version 1.11* Really difficult to connect to, the app is also buggy ### 1/5 — Don’t do it *2025-01-18, version 1.11* I am not the most tech savvy person but this app but this is ridiculous. If you are interested in becoming frustrated it is the app for you. Getting this connected is almost impossible. I lost connectivity after I had the app in place for almost two years and have yet to reestablish. If there were a no star option it would still be too high ### 1/5 — Time To Do Better Kessil!!! *2025-01-04, version 1.11* This app and dongle have become useless. Major connectivity problems with a360x lights. ### 1/5 — Horrible *2024-12-08, version 1.11* This app will kill your livestock. While have this app controlling your settings it will randomly take on a mind of its own. For instance I have it set to ramp down at night eventually turning off at 7 pm, I woke up one night to find the light blasting at full power when it should have been off. The next day I found an angelfish, that I had for years, somehow came down with some sort of infection or ick. I am absolutely disgusted with Kessil for this, never again will I buy another product of theirs. ### 1/5 — Beyond Buggy *2024-10-15, version 1.11* The app when you can get it to work is fine. I’ve found that directly connecting to the Ap9X or WiFi dongle own internal WiFi yields the best results. I noticed that after IOS 18 I’m logged out and can no longer log in through Google which means I cannot backup my settings. This is a huge problem for someone like me that has multiple clients using Kessil lighting. ### 1/5 — AP9X App is horrible!!!! *2024-09-15, version 1.11* This is literally the worst app I’ve ever used. Such a hassle to connect to the lights through WiFi. So disappointing as the lights themselves are very nice. Please address this Kessil! ## Most praised reviews (10 highest-rated) ### 5/5 — The app works great, the problem is your network. *2024-02-23, version 1.11* This app works flawlessly. No issues with connectivity or function. If you’re having problems with it, it’s because you don’t understand how to setup your network properly. Which is a problem for most people, because most people aren’t generally tech savvy enough to handle even simple tech. No offence meant to anyone, but if you’re having problems it isn’t the app, it’s your network, your skill set, or both. The majority of reefer’s are either old dudes struggling with tech, or young dudes that are too adhd to learn and read instructions. You’ll see most reef apps have bad reviews. Same thing with Mobius which also works just fine. It’s not the app makers fault that the general public can’t figure out how to work their tech. ### 5/5 — I like how it controls my lights *2020-12-08, version 1.8* The lights themselves are amazing and the app helps me control them so I can make my tank look as good as possible ### 5/5 — Awesome app & product *2020-10-23, version 1.8* Super intuitive & solid app for an equally solid AP9X light. Great customer service too. Such an incredible step forward for the Kessil brand. Keep up the good work! ### 5/5 — Works extremely well for me *2020-10-23, version 1.8* Light setup was easy and quick. I enjoy the ability to move presets between lights so all my tanks can run the same schedule ### 5/5 — Great Lighting control *2020-10-22, version 1.8* Pretty happy on the Kessil home system lighting, control is easy to setup and understand. Haven’t had any issues with the other features either, highly recommend ### 5/5 — Works well *2020-10-20, version 1.8* Does the job well of controlling my ap9x. I like the control options of it as well with the acclimation mode. ### 5/5 — Easy Setup *2020-10-15, version 1.7* The connection process was really fast! The QR code on the box made connecting super easy. ### 5/5 — Kessil wifi with AP9X led *2020-10-14, version 1.7* I use kessil wifi with my AP9X and it works perfectly. It’s very easy to navigate this app, didn’t had any problem with it so far . ### 5/5 — Works Great *2020-10-14, version 1.7* Much better than the spectral controller and being able to link multiple tanks in one hub is awesome! ### 5/5 — Complete control! *2020-10-14, version 1.7* Great app with intuitive controls and everything you need to setup your lights how you want. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
