Kick counter

I have no idea how these work 😅 do I just do it everytime baby gets active? Or just once a day? And it counts how long it takes to get to 10 kicks or movements? On average atm it’s about a minute but like I have an active baby and he doesn’t stop at 10 😂 he does still move a lot during the day too but I can feel him a lot more when I’m laying down I only downloaded it last night but if there’s any apps that are better for it I’m open to suggestions
