A recorded workout does not guarantee a high Activity Score. The score summarizes the movement and workout information available for the day, so one session is only part of the picture.
Check whether the workout arrived
Open the activity details in Zolt, then find the same workout in Apple Health or your connected health platform. Confirm that the type, duration, start time, and heart-rate record look correct.
A workout can be missing, duplicated, assigned to the wrong date, or recorded without the heart-rate information expected for a supported cardio session. Those cases can make the day look different from the workout you remember.
Look at the rest of the day
The Activity Score can also reflect everyday movement, including steps and other records available from your source. A hard gym session followed by a very quiet day is a different activity pattern from the same workout plus regular movement.
That does not make the workout worthless. The score is summarizing the available day, not grading your effort or character.
Check the source setup
Activity data may change when you pair a watch, switch devices, or allow more than one app to write workouts. Review:
- which device recorded steps and movement;
- which app wrote the workout;
- whether Zolt has the required read permissions;
- whether two sources created duplicate sessions; and
- whether the phone stopped contributing some records after a watch was paired.
Make corrections in the source platform when possible so the original record and Zolt remain aligned.
Activity Score and cardio load answer different questions
Activity Score covers the broader day. Cardio load focuses on supported cardiovascular workouts and their available heart-rate intensity within your recent training pattern.
A workout can meaningfully affect cardio load without producing the Activity Score you expected. Open both views rather than using one as a substitute for the other.
What to do
- Confirm the workout appears once in the source platform.
- Check its date, duration, type, and heart-rate record.
- Review the day's movement and steps.
- Confirm the active device and permissions.
- Compare the next correctly recorded day.
If the source is complete but Zolt is missing or duplicating the workout, contact support with the date, source app, activity type, and screenshots.
The Activity Score does not set your calorie target directly. See Do active calories change your Zolt target? for that distinction.
