Thats like having a car that always drives me somewhere I don't want before it drives me where I want. What the actual f*ck. How are people okay with having such garbage in their homes. Why not just buy an analog spring scale...
Because digital scales have features that analog ones do not. And contrary to an earlier assertion that 'almost all' scales lie to get consistent results, this is very much not true. There are reputable digital scales that do not behave that way.
I suspect the scale being accurate +-30g is sufficient for personal weight management unless you’re a professional boxer or need it to be exact for some reason.
I can find mechanical scales very easily in the Netherlands, but they're more expensive. On Alibaba I see that digital bathroom scales are about $2.50 and with WiFi/Bluetooth it's $6, mechanical scales are double that at $12 while also taking up more volume (more pallets and containers). With volume scale and unique designs, your own skin on the apps, and market specific packaging the margins are only going to get better for the (connected) digital scales.
You have to take into account that a digital scale, especially one with an app, is going to be collecting endless amounts of data about you and selling it to anyone willing to pay. Your digital scale will end up costing you again and again for the rest of your life, every time someone uses that data against you. You'll just never be told when it's happening.
