There is currently no account sign-in or backup import to recover your hydration history or room on a new installation. Restoring Plus does not restore a previous guest account's progress. Internet access is needed for initial setup and social features. Sipling is a general wellness app, not medical advice. Hydration needs vary; adjust your goal to suit you.
