How do I cancel a subscription bought through an app store

A subscription like this is cancelled in the store's own settings — the app can't do it for the store.

1. Open your account settings in the app store
2. Find the subscriptions section
3. Select MomsLab and turn off renewal

If you subscribed on the website rather than in a store, it's a one-off payment that doesn't renew by itself — there's nothing to cancel.
