No, there is no difference in terms of access to the content. The only difference is regarding subscription management. Apple handles their own In-App subscriptions. So, when you purchase from within the Mimo iOS App, you can manage your subscription through iTunes (https://support.apple.com/HT202039). If you've purchased Mimo Premium on our website or the Mimo Android App, you can manage the subscription there (https://getmimo.com/settings).
