I'm here to WARN anyone who is thinking about buying an Anova. If I can make the choice again I would never buy it, it's an utter crap and the official team obviously have no ability to fix anything except making the phone app more and more unstable, after so many years.
I usually used Anova to cook eggs before I went out to gym. When I was in the gym, my neighbors called
the police once just because it kept beeping with extremely annoying high pitch noise when the waterline is below the minimum requirement, and the app quit automatically when I was working out, didn't get any notification, and lost connection to the cooker when I re-opened it. When I was at home doing something else in another room, it beeps after the cook is done just like anybody else who complained above, I don't usually have time to go to the kitchen and turn it off because I was busy with something else more important like in an online conference and the app loses connection or lags very often, so I had to endure the beeping noise for quite a while which drove me nuts.
And not to mention the app is never improved, outdated design like years ago, with more and more bugs and I had to look for an old version to work with it properly.
I don't recommend this to anyone. I'm selling it, I've given up hope to the team and support.
If you have babies, pets, older people or anyone who's not capable of handling the cooker when you are not at home, DON'T BUY IT, go for something else that won't kill the one you love by the most annoying noise from a cooker.
