Minimal sample showing how to gate rep counting on the SDK's pose-check feedback — so counting only starts once the user is in the correct starting pose for the exercise.

Mirrors the iOS CounterDemo and Android composeapp patterns.

The QuickPose SDK runs per-exercise pose checks every frame. When the user isn't in the required starting pose (e.g. not floor-facing for push-ups), the SDK surfaces a feedback string via onUpdate. While that feedback is non-empty, we simply don't feed the measure value into the counter:

const counter = useRef(new QuickPoseThresholdCounter());

const handleUpdate = (event) => {
  const {results, feedback} = event.nativeEvent;
  const measure = results?.find(r => r.feature === 'fitness.pushUps')?.value;

  if (!feedback && typeof measure === 'number') {
    const state = counter.current.count(measure);
    setCount(state.count);
  }
};

That's identical to the iOS/Android samples. The two-threshold hysteresis inside QuickPoseThresholdCounter (enter 0.6, exit 0.3) handles noise; not calling count() while feedback is present is what prevents false reps during setup.

The first time counter.state.isEntered flips to true is the exact moment the user starts their first rep. Hook your audio library there — Expo apps typically use expo-av / expo-audio; bare RN can use react-native-sound.

const state = counter.current.count(measure);
if (state.type === 'poseEntered' && state.count === 0 && !hasPlayedGo.current) {
  hasPlayedGo.current = true;
  playGoSound();
}
