I don't know. She is reliable when walking outside.

Hello
I've been using it for 4 weeks, so far only when jogging and hiking, but here regularly and intensively. I got it because of the heart rate monitor, but it can be connected to the app at the end so that all the data is saved.

Routes, distance, time etc. are recorded. However, I find it annoying that the watch has to sit really snugly on my wrist, otherwise the heart rate isn't reliable. I keep moving it back and forth....until it works.

Otherwise, for this price, it has served me well so far.
Greetings

The question is whether indoors or outdoors?
