Currently, you can choose between the following partner apps that can be directly connected to Lifesum:

- Runkeeper
- Withings for the weight
- Fitbit
- Health

For those partners that you cannot find as a direct partner in the app:
You may want to try and see if this partner can be synced with Health.

That way you can sync the data with Lifesum. Just connect the app with Health, and Health with Lifesum.
