As a tech in the field it can never find serial numbers or add service logs. ### 1/5 — Fix the downloads at least please *2026-02-12* Only downloads blank pages supper helpful! ### 1/5 — Minimal usage and broken *2025-12-22* Agree with all the other reviews. App is not useful and I was not able to register ### 2/5 — Buggy and missing features *2025-07-09* The app allows useful but very limited controls. Why am I unable to adjust recirc settings etc from the app? That seems like a really dumb oversight. Also, much of the EMS data that is supposed to be displayed simply doesn’t populate in the app at all. No support from Navien, they don’t respond to questions or feedback. Overall the app is a major disappointment. ### 1/5 — What is the app for *2025-06-21* Mine didn’t even come with a remote . So frustrating. ### 1/5 — As an installer... *2024-12-27, version 1.6.3* This app is beyond useless. Can't even download a manual. ### 1/5 — Totally useless *2024-11-05* Does not seem to register my product. Not sure what this app is supposed to do but it is useless. ### 1/5 — No purpose for the homeowner *2024-09-05, version 1.6.1* If you’re a homeowner, don’t bother. This app appears to be for installers who want to get rebated on fees. App is buggy and seems to be a sales gimmick. ### 1/5 — Pointless *2024-03-29* I was planning to use the app to track the maintenance for my new water heater, but the app can’t find my water heater’s serial number which is required for that. ### 1/5 — Trick app *2023-08-07* So you probably want this app just when your unit needs fixing. But the app does not let you create an account. It fails on the Country table. Seems they did not do basic QC. Does that indicate how my new heater will perform? ## Frequently asked questions about Navien ### What is Navien used for?
