It's not really. Before my galaxy watch I had a amazfit gts 2 mini which cost me 70 euro, has GPS tracking, barometer, heart rate and SpO2, the works. It is really privacy safe if you pair it with the gadgetbridge app. It works fine , and while you can't install any apps it has a one week battery life even after 2 years of using it. Despite being tiny and light. Not bad at all.
