The app constantly has glitches and bugs and I can’t even connect to my account/wifi with this anymore :( very disappointed ### 1/5 — Hardware and software garbage *2025-10-21, version 3.3.1* These are horrendous to set up. And the wifi connectivity range is terrible with these devices as well. Returning the junk as well as deleting this app. ### 5/5 — Way better than Neptune *2025-09-19, version 3.3.1* This is hands down the best controller on the market I have 6 devices linked up in a collective flawless ### 1/5 — Buy Neptune Instead *2025-07-26, version 3.3.0* I have had this system and this app for three years. All I have to say to justify my one star is that I wish I had bought Neptune instead. ### 2/5 — Lots of issues *2025-06-18, version 3.3.0* keep getting notifications from a sensor that was fully deleted and re-added. Really irritating and annoying cuz you think that something’s wrong and go to check your tank and nothings actually wrong. pH probe didn’t work correctly either one that came with the package was defective, won’t measure ph properly or recalibrate properly so it’s giving the wrong readings, ### 2/5 — Wifi outlets connectivity issues *2024-07-06, version 3.0.5* Since last update I'm unable to connect any wifi powerstrip. 👎🏽 ### 3/5 — Languaje…. *2024-06-25, version 2.6.4* Products in Mexico are booming, however it would be great if it were offered in a Spanish version ### 2/5 — Works well enough *2024-04-24, version 2.6.4* This app does not feel like it was designed for end users. But rather designed by a tech person, possibly with a Windows/networking background, for a certain type of tech person. The app requires the user to log back in with username and password every 30 days. Really? Every 30 days? For some wave pumps? Seems much more like an designer’s/team’s design flex rather than practical and useful for users. The controller nearly always remains connected to the cloud. When a connection is lost for 15 mins +/- a notification from the app is displayed. Best use of this is it lets me know WiFi is being wonky. The function of the pumps are unaffected. When WiFi is down the app does allow pump connection via blue tooth. I like the products associated with the app, but the app is “meh.” Two stars. One star lost because of the GUI. An additional two stars lost because of the forced log out and reauthorization every 30 days. ### 4/5 — Good peace of mind *2023-10-16, version 2.6.3* Got a water level sensor and a temperature probe about a year ago and I really like knowing my tank’s (freshwater) status and that it’s safe, love the alert features too, only downside is sometimes you have to sign back into your account when you open the app which I could see potentially being an issue. ### 3/5 — Watch app coming? *2023-09-16, version 2.6.3* Would be great to have some functionality on a watch app…even if only to switch modes to feed or water change. Otherwise a good app. ## Frequently asked questions about HYDROS App ### What does the HYDROS App do?
