I Didn't Know Buying More Than One Device Was A Crime

I’ve had a Haylou Solar for a long time, and it still works perfectly fine. Recently, I bought a new Haylou S6 watch and tried to add it to the Haylou Fun app.

That’s when I discovered something ridiculous: the app apparently allows only one watch to be connected at a time.

I was genuinely disappointed. Then I thought, okay, I’ll just use my secondary phone. I downloaded Haylou Fun, logged into my account, and added the new watch there. Everything seemed fine.

But when I came back to my primary phone, I found that I had been automatically signed out.

So my question to Haylou is:

Do you not want your users to own and use multiple Haylou devices?

Are you saying I’m somehow wrong for buying more than one of your products? You don’t want your customers to use multiple devices in parallel? Do I need to choose which Haylou product I’m “allowed” to use?

Or is the message simply: “Congratulations on buying multiple Haylou products. Now you can only use one of them at a time.”

What kind of product ecosystem is this?

I genuinely don’t understand the logic behind this limitation. I already own your products, I like your products, and I chose to buy another one. Why make the experience worse for customers who actually buy more of your devices?

Haylou, please fix this. Your customers should not have to fight your app just to use the products they paid for.
