## What is 3D Pacer?

Stop staring at your watch. 3D Pacer turns your target pace into sound you can follow without looking.

Put on your headphones and start running. Using spatial audio, 3D Pacer places your pacer in the space around you:

- Too slow? The sound moves ahead of you, so you catch up.
- Too fast? It drops behind you, so you ease off.
- On pace? It runs right beside you.

It's the feeling of running with a partner who's always at exactly the right speed, without anyone setting the pace but you.

FREE RUN
Pick a target speed, tap Start, and go. Adjust up or down at any time, and the pacer follows your new target instantly. When you're done, tap Cool Down and your pacer eases back to an easy walk.

BEATS AND VOICE CUES
Footstep beats timed to your target pace help you settle into a steady rhythm, and a coach voice tells you when to speed up or slow down, with no screen needed.

SMART TRACKING
Auto-pause stops the clock when you stop and picks back up when you move. Outdoors, GPS learns your stride so your speed stays accurate, and on a treadmill a quick calibration does the same.

HANDS-FREE WITH SIRI
Start, pause, resume, cool down, and finish runs with your voice. Just say "Pause 3D Pacer." Your phone can stay in your pocket or armband the whole time.

APPLE HEALTH
Save your runs to Apple Health as workouts, with your route on the map in the Fitness app.

SAVE AND SHARE
Every run is saved on your phone with time, distance, and average pace. Share a run with a friend, and they can race it as a ghost in 3D Pacer for free.

PRIVATE BY DESIGN
Your runs stay on your iPhone. No account, no ads, and no tracking.

3D PACER PRO
One purchase, yours to keep. No subscription.

- Planned runs: Build a run before you head out. Set the distance, a warm-up, your main pace, and a cool-down, and 3D Pacer moves you through each stage automatically. Just listen and run.
- Ghost runner: Race your own past runs or a goal time, and hear exactly where your ghost is, ahead of you or behind.
- Spoken pace updates: Hear your pace every quarter mile, every mile, or every few minutes, plus a quick check 30 seconds in.
- More sounds: Pavement footsteps, shaker, and metronome, on top of the free gravel footsteps.
- Complete run history: The free version shows your three most recent runs. Pro shows every run you've ever saved, with your time-on-pace trend.

Works best with stereo headphones or earbuds so you can hear where the pacer is.
