Can’t get back in. ### 3/5 — System outage *2025-09-14* There seems to be a system outage for last several hours. The app simply won’t open and I can’t access my account on web site. It would be nice to receive some sort of email or text notification that this is happening and when to expect resolution. This system is monitoring critical home infrastructure. It was expensive to purchase. We expect better. ### 1/5 — iPad does not support landscape mode *2025-08-26* While the app works and is generally responsive on the phone and iPad, the fact that the iPad version does not support landscape mode is inexcusable. Many homes use iPads as a control center, and in my case, I use it with a keyboard. Even the most basic apps support portrait or landscape mode. It’s straightforward to implement. I also wish the system did a better job of reporting low batteries so they can be changed before alerting of a low status. ### 4/5 — Descent App - Great product *2025-06-06* Used this for over 5 years. App gets the job done, needs a few improvements to catch up. Product is DEFINITELY worth the premium price (expensive). I’ve tried them all…many homes. Tons of product hardware add-ons available to manage complex large homes. Insurance company Chubb requires it and agent told us Leak Defense is the best in the market (haha, Chubb even owns another brand but said it’s not as good.) ### 2/5 — Love the product, but the app times out constantly *2024-01-20* I love the protection this system provides, however I’m really struggling with the app. More times than not, when I try to access the app, it immediately times out and appears to give me an option to report an error, however nothing happens if you attempt to report the error. It just locks up the screen and you have to exit the app entirely. Please fix! ### 1/5 — Terrible App *2024-01-18* Despite having access points throughout my new home and outstanding internet speed (1GB), this app doesn’t work about 40% of the time. Thus, often when an alarm notification is sent to my phone, it can’t be silenced via the app. Instead a “Server Error” appears, with a suggestion to report the error…which does absolutely nothing. Were it not a requirement of my insurance provider, I would throw the entire Leak Defense system in the trash where it belongs. PS - customer support is worse than the app. ### 1/5 — Terrible *2023-04-18* If I could give 0 stars I would. App itself is very slow to respond and alarm routinely goes on at 3am usually because a toilet is running. ### 3/5 — Good but could be improved *2020-12-06* This is a good app for controlling the Hydrosolutions Leak Defense system. The app permits one to remotely reset or turn on/off water to the house. However, It does not support Face ID. The app does not allow one to use long or complex passwords even though such passwords are acceptable when used in the website alternative to the app. ## Frequently asked questions about Leak Defense System ### What is the Leak Defense System?
