The app will always be free to download and use. To access content within the app, you will need to have signed up for/purchased a myDNA membership at some point. To sign up for an account, you can register here.
Once in the app, ongoing meal plans, fitness plans, new insights, recipe/exercise exploring and home feed content require an active myDNA membership to access. You will receive 30 days free membership with your purchase of a myDNA Personalised Wellness Kit, after which you will need to have an active subscription to access these premium features. You can read more about subscription costs here.
Even if you cancel your membership or do not have an active subscription, any insights you gained during your time as a myDNA member are yours to keep. You will always be able to access them in the Insights section of myDNA Unlocked, regardless of your subscription status. However, you will not gain any new content/insights or be able to access your personalised plans unless you resubscribe.
