The Zolt Activity Score summarizes the movement and workout information available for the day. It gives everyday movement and recorded exercise a common place in the app.
The score is not a calorie target, and it does not tell you to eat back the calories shown by a wearable.
Common questions
- Why is my Activity Score low after a workout?
- Do active calories change my calorie target?
- Why did one workout add so much cardio load?
What contributes to the view
The Activity view can use:
- everyday movement, including steps and other activity recorded by your source;
- recorded workouts;
- heart-rate information available for supported workouts; and
- the training status or recovery context shown in Zolt.
The detail screen tells you which records were available. A hard workout may be only one part of the day, while a high-movement day can register without a formal workout.
Where the data comes from
Zolt reads activity and workout records from the connected health platform. The phone, watch, or another app may be the original writer.
That source matters when a value is missing or duplicated. If two apps write the same workout, or the phone stops contributing activity after a watch is paired, the Activity view may not match what you expected.
How to read the score
Use the overall number to orient yourself, then inspect the components.
| What looks unusual | First check |
|---|---|
| Steps or movement are low | Confirm the expected device recorded the full day |
| A workout is missing | Check the workout in the connected health platform |
| A workout appears twice | Review the apps writing workout data |
| The score differs from yesterday | Compare both movement and workouts, not only one session |
| The target looks different | Check training status and recovery context |
An intentionally quiet day is not automatically a failure. Read the score alongside the plan for the week and how you feel.
Activity Score versus cardio load
The Activity Score summarizes today's movement and exercise. Cardio load describes how recent cardiovascular training relates to your longer-term pattern.
Use Cardio load, fitness, fatigue, and form when you are deciding whether a training pattern is building, steady, or unusually demanding.
Activity does not set your calorie target directly
Wearables estimate energy expenditure from sensor data and profile information. Those estimates are useful for activity context, but they are not treated as a direct calorie credit in the adaptive plan.
Read How accurate Apple Watch calories are for the difference between a wearable estimate and the nutrition-and-weight relationship Zolt uses for planning.
If the score looks wrong
- Check the original activity and workout records.
- Confirm that Zolt has the required read permissions.
- Check which device and apps wrote the data.
- Look for duplicate workouts or overlapping sources.
- Confirm that the correct date and time zone are shown.
If the source record is correct but Zolt is missing it, contact support with the date, activity type, source app, and screenshots of both records.
