How OneWay works

An educational tracking tool for iPhone. Your logs stay on your device.

Logged calories

Every calorie you eat should be logged in OneWay. Looking up and typing calories yourself teaches you what’s in your food — not a black-box database guessing for you.

With OneWay Smart, save meals you eat often and re-log them in one tap on repeat days.

Burned calories

OneWay reads your total burn from the Health app as Active plus Resting — movement and the energy your body uses at rest.

Together they estimate your total burned calories for the day.

Requirements

OneWay works best with a few tools that sync through the Health app.

Activity tracker

Active and resting energy burned sync through Health for your daily burn total — usually from Apple Watch.

Smart scale

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

iPhone

Calorie logs and settings stay on your device. No cloud account required.

Your daily tasks

Simple habits that keep the equation honest.

  • Log everything — Almost everything you eat has calories. Your job is to log those calories in OneWay.
  • Weigh yourself — Weigh yourself consistently. OneWay tracks the trend on your dashboard — and with OneWay Smart, your weigh-ins help power Smart Burn Calibration.
  • End the day in a Deficit — At the end of the day, your Dashboard should show a Deficit. This is the hardest part and will take time to hone in your daily routine. Keep Trying!
