Connect Health app

Burn and weight read from the Health app. In OneWay, tap Reconnect Health app in Settings, or open Settings → Privacy & Security → Health → OneWay: Deficit.

Weight

Sync a smart scale to Apple Health, or log weight in the Health app. Chain: scale → Health → OneWay.

Burn

OneWay reads your total burn as Active plus Resting. An activity tracker synced to Health — usually Apple Watch — supplies those numbers.

Why look up my calories instead of using a food database?

So you learn what food costs in calories. Eventually you will maintain — not diet — and you will not want to rely on an app forever. OneWay sets you up for long-term success, even after you delete it.

What about drinks or small bites?

If it has calories, log it — including drinks and anything that has calories. Small omissions add up fast.

Burn Calibration

The Health app’s burn total is an estimate — it can run high or low for your body. Burn Calibration lets you nudge that number up or down in Settings so your deficit reflects reality.

Smart Burn Calibration

With OneWay Smart, Smart Burn Calibration can recommend — and optionally auto-apply — a calibration based on your logged calories, burn, and weight over time. It runs locally on your device.
