2. Open Fitbit.

3. Select Join Fitbit, or Log In if you already have an account.

4. Tap No Fitbit Yet at the bottom of the screen.

5. Tap "Set Up Your Phone."

6. Enter your height.

7. Enter your gender.

8. Enter your weight.

9. Enter your birthday.

10. Enter your name, email address and password.

11. Your iPhone 5s will now automatically track your steps, miles traveled and calories burned with the Fitbit app open.
