Duplicate workouts in Apple Health: how to fix them
By Wellhero · Published
If one workout appears twice in Apple Health, check which app saved each entry. Two apps may have recorded the session, or a connected service may have sent a copy back. Choose one route for saving that session to Health, then review the existing duplicate separately.
Start with one affected workout. Compare its sources and times so you can keep the next session complete and avoid another copy.
Find where the duplicate exists
On your iPhone, open Health, then Browse, Activity and Workouts. Open Show All Data and find the affected date. Inspect the entries for the session and note the source of each. Data Sources & Access lists the apps and devices contributing to that category. Apple's Health data guide explains source controls; labels may differ with your iOS version.
Compare the start and end times with what you actually did. A run followed by a separate cool-down can be two legitimate sessions. A similar title alone is not enough to decide that one should go.
- If Health has two entries for the same session from different sources, inspect how both sources save or sync workouts.
- If both entries name the same source, note that in your support request. Disabling an unrelated app will not explain that pair.
- If Health has one entry but another app shows two, investigate that app's import or display first. Keep the single Health record while you do so.
Keep screenshots of the affected entries and their source details before changing anything. Use them to compare the records afterward.
Choose which app saves the workout
For the affected activity, write down which app you started to record it and which connected services receive it. If you started both Apple's Workout app and another recorder, decide which recording you want to keep for future sessions. If you started only one recorder, look for a service that imports the workout and sends it back to Health.
Health gives apps separate permission to read and write each data type. Reading Workouts lets an app use existing records; writing Workouts lets it save records. Apple describes these permissions separately.
Open your profile in Health and find the connected app under Apps or Apps and Services. Check the Workouts permission in its write section. If that app is the confirmed extra writer, turn off that permission while retaining the read permissions you use. Do not turn off every health category to solve one duplicated workout.
Make this decision for your actual recording setup. An app that duplicates watch-recorded runs might also be your only route for bike rides recorded elsewhere. Before disabling its export, check how those rides will reach Health.
Will changing data-source priority remove the duplicates?
Apple's source priority controls which source Health prefers when several supply the same data type. It is not a command to delete a saved workout. Check the individual records again after changing a preference, and do not assume another app uses Health's display rules.
Check the two directions of Strava sync
Open Strava's You tab, then Settings, Manage Apps and Devices, Health. Its integration guide describes separate controls for importing Apple workouts and sending activities to Health.
If Apple's Workout app records your sessions and Strava is the confirmed extra writer, turn off Send to Health. Leave Automatic Uploads on to keep importing eligible Apple workouts.
If Send to Health is your only route for other activities, arrange another way to save them before switching it off.
Strava accepts Health imports only from Apple's native Workout app, recorded within the past 30 days. A workout from another company's app is ineligible even if it was recorded on Apple Watch.
Copies already saved need the separate review below.
Review the copy already saved
Open both versions before deciding which to remove. Check duration, route and any heart rate detail you need. Keep the complete record you intend to use, and export a copy through the recording app if you need a backup and it supports export. A screenshot preserves evidence of the problem, not a restorable workout file.
Once you have identified an unwanted copy, Apple's Fitness guide gives this path: Summary, Sessions, then swipe left on the workout and tap Delete. The confirmation offers two different actions:
- Delete Workout Only removes the workout.
- Delete Workout & Data also removes its health data.
Read that choice carefully. Removing an extra workout row does not mean you also want to remove its associated measurements. If you cannot distinguish the two records, leave them in place and ask the recording app's support team to help. Avoid deleting an entire source's history to fix one session.
Do two workout entries mean my calories doubled?
The two entries alone do not establish that. Check the day's Active Energy total and the records behind it, then check the total in the app you use. Workout lists and daily summaries are different views; verify the value that looks wrong before removing other data.
Check the next workout and its analysis
After your next normal session, check that Health contains the intended workout once. Then check that your other apps received it and that the details you rely on are present. If duplicates return, note the source names, recording app, start time and when the second copy appeared. Include app and iOS versions when asking for help.
In Wellhero, open Profile, Apple Health Data, then Health Status and Workouts to inspect synchronization. Open the workout report to review its heart rate chart and recording coverage. The Wellhero workout analysis guide explains those details and TCX export.
For the meaning of the activity score after checking the records, read daily and workout Strain. If the workout is present once and your question is about a lower HRV afterward, see HRV after exercise.
