Review summary

Reviews consistently describe Cozytouch as buggy and unreliable. The most persistent problems are login failures and credentials not being remembered, forcing frequent logins; connectivity issues that keep the boiler/app offline or fail to connect to the server; overall stability problems with crashes and very slow responses. Users also complain about limited heating controls (no continuous heating, scheduling-only options) and a confusing UI, plus unhelpful or slow support. Taken together, the app underperforms, making it hard to manage multiple heaters or trust its status.

Pros

Cons

Frequent login problems: the app requires login on every start and does not remember credentials, with random logouts.
Cannot connect to the boiler or server reliably: devices show offline, repeatedly fail to connect, and server errors prevent control.
Stability and performance issues: crashes, very slow refresh, long loading times, and unresponsive UI.
Limited heating controls and confusing interface: only time-based schedules, no continuous heating, no load balancing, and unclear status indicators.
Support is slow or unhelpful: reported issues often receive little to no response.

2026-07-25	St*****	An absolute mess for my Atlantic Vertigo water heater. The UX is tragic—turning off water heating is unintuitive, clunky, and painful to navigate. The app constantly gets stuck on "Server unavailable", throwing connection errors and making it impossible to add rooms. It provides zero energy tracking and fails to display the actual water temperature inside the tank. Even the Absence mode is a UX disaster, completely counterintuitive and unreliable. A total failure for a Wi-Fi device.

2026-06-12	Ми*****	J'ai acheté le chauffe-eau Atlantic Vertigo Wi-Fi en espérant un appareil connecté, mais c'est une grande déception. Il n'a aucune véritable fonction "smart". L'application est inutile.

2026-06-11	Lu*****	I don't want to create an account and give someone my personal info only to make an electric water heater work. It's ridiculous. And stupid.

2026-05-09	M *****	Very laggy app (feels like we live in the 90ies), no way to add the devices to google home. PLEASE HIRE A REAL PROGRAMMER (or have AI write the app).

2026-04-06	De*****	It annoying to request log in each time it is started. Not sure if this is country restriction,but for water heater it does not show anything in practice - if device is on or off, cannot adjust the heating temperature , nothing manual. The app is totally useless.
