Activity mismatch between Paceline and my device

Why your activity data may look slightly different in Paceline

Small differences between your device app and Paceline are normal and expected. For example, Apple Health might show 4,203 steps on a day while Paceline shows 4,201.

Paceline shows the activity data your fitness provider (like Apple Health, Garmin Connect, or Fitbit) sends us. We don't recalculate or adjust it.

Why small differences happen

• Paceline uses your provider's data as-is. Steps, elevated heart rate (eHR) minutes, sleep, and workouts come straight from your provider. Small gaps of a few steps or minutes usually come from rounding or timing on the provider's side.
• Your device may update after Paceline syncs. Your device app can keep adjusting totals after Paceline has already received them. The next sync usually brings them in line.
• Workouts can take time to arrive. Workouts typically sync to Paceline within the same day, as long as your data can sync (see Keep your data syncing smoothly below). Timing still depends on when your provider sends the data to us, so a workout may not appear right away.
• Weeks may be counted differently. Paceline weeks run Monday 00:00 → Sunday 23:59 (your local time). Some devices default to Sunday–Saturday, so weekly totals won't match unless you update your week start in your device's app settings.

Keep your data syncing smoothly

• Update the Paceline app to the latest version
• Turn Background App Refresh ON for Paceline
• Sync on a strong Wi-Fi or cellular connection
• Keep your phone charged above 50%
• Open Paceline at least once a week

If you haven't opened Paceline in a while, your first sync will take longer than usual. This is expected, since there's more data to bring over.

When to contact us

Before you contact us, try the troubleshooting guide for your device here. A difference of a few steps or minutes doesn't need any action. Reach out if:

• A full day of activity is missing
• A workout still isn't showing 
• Your data hasn't synced within 24 hours of opening Paceline after a long break

 If your data still doesn't appear, contact us and include:

• The dates where you see the difference
• A screenshot from your provider's app (for example, Apple Health) for those same dates showing the activity totals

Since we don't have your device in hand, this helps us find where the sync is getting stuck.
