apple watch is not accurate in counting steps

Hi ..

See if calibrating your watch helps. Instructions here > Calibrating your Apple Watch for improved Workout and Activity accuracy - Apple Support

And make sure your watch os is up to date. On your iPhone open the Watch app then tap General > Software Update

And make sure your watch fits properly > Wearing Apple Watch - Apple Support

After calibrating your watch, you want to walk with your iPhone with location activated (in your privacy settings). Your iPhone will monitor your distance and calibrate your watch as you walk based on algorithms. The more you do this the more accurate your step count will be. Also keep in mind that, as with any activity tracker, your motions are counted by sensors; tip-toeing or walking softly most likely will not register. Conversely, if you flail your arm constantly, it will register these motions as steps. Also, if your arm that holds your watch is inactive while you walk/exercise your count will be less accurate. Hope this helps...
