## What is ASTEP?

Step today. Change tomorrow.

ASTEP shows an estimate of the body fat you burn on every walk or run. As you move, it also shows how much that adds up to in a week, a month, six months, or a year if you keep it up every day.

■ Watch it grow as you move
During a workout, the body fat you burn grows as an orange circle, one for every 10 g. Big numbers show this workout and where a year of it takes you.

■ See a year ahead on the home screen
The big circle is a one-year estimate at your current pace. The white circle inside is what you've burned so far, and it grows as you keep going.

■ Every active day at a glance
The calendar marks the days you moved. Tap a day to see its workouts. The graph shows your progress from day one to a year later.

■ Track with Apple Watch alone
Start and finish right on your Watch, no iPhone needed. A complication shows this week's total.

■ On your Lock Screen
During a workout, your progress and time appear on the Lock Screen and in the Dynamic Island.

■ And more
- Walking and running, with calories based on your speed
- Auto-pause when you stop at a light
- Saves workouts to Health
- A daily reminder, skipped on days you've worked out
- Syncs with your own iCloud. Nothing is sent to our servers

■ PLUS (one-time purchase)
Set a goal weight and a date to see a daily exercise estimate to get there. Choose from five color themes for the whole app. Not a subscription, and it never renews automatically.

■ Please note
Calories and body fat are estimates based on METs, your weight, and time. This is not medical advice. Actual results vary with diet and your body.
