What is Pacer?
Pacer is a watchOS-only step tracker that shows whether you’re ahead or behind your daily step goal in real time, not at end of day. It spreads your goal across your active hours and surfaces a live ahead/behind number on a watch-face complication.
How is Pacer different from Apple’s Activity Rings?
Activity Rings show your step total at end of day. Pacer shows whether you are ahead or behind your goal right now, mid-day, so you can correct course while there is still time.
Does Pacer collect any data?
No. Pacer collects nothing. HealthKit step counts stay on your watch — no servers, no accounts, no analytics, no third-party SDKs.
How much does Pacer cost?
Pacer is $3.99 once on the App Store. No subscription, no in-app purchases, no ads.
What devices support Pacer?
Pacer runs on Apple Watch with watchOS 26.2 or later. It is watch-only — there is no iPhone companion app.
Is Pacer open source?
The app itself is closed source. This marketing site is open source on GitHub.
