Less to track, more room to live. • Prefer the full picture? Detailed mode keeps all your numbers and trends. Switch anytime in Settings. • A cleaner start — open the app and you're right in, no setup screens. • Smoother recommendations that match whatever your body is doing today. Everything still stays on your device. Thanks for training with ONDA.
