The App is free to download from your favorite store (App store; or Google Play).

If you are a company offering caregiving in dementia, such as home care, residential care, assisted living, CCRC, etc., please contact info@mentia.me for a professional account.

If you are creating a care circle for the first time for a player, and you have not yet created an account, you have a one-month free trial during which time you can create as many Players’ profile (a Player is a person with dementia) as you wish. (For example, you may be a professional carer wanting to try Deva World with a number of different Players.) Once the trial month has passed, your credit card details are required to continue our services. We charge a subscription fee of $20 USD per month per Player. Credit Card details are securely stored by the online payment processor Stripe, and are not installed on Mentia’s servers. Subscription features include unlimited sharing of Deva World within a Player’s care circle, the opportunity to customize Content to enhance a Player’s experience; the history of your Player’s Sessions, including duration times and Session reports (see “Sessions” section on the Player’s profile on the Dashboard); access to new developments of Deva World. The first User to create an account will be responsible for the subscription (the “Subscriber”), however this responsibility can be reassigned to another User by pressing the handover button on a Player’s profile. The Subscriber can cancel any player’s account at any time by pressing the Cancel button on the Player’s profile. Professional caregivers are invited to take advantage of our professional packages. Please contact us directly about this at info@mentia.me

If through our sharing system you have been invited to join a Player care circle, then your account is free for the duration of care circle and at the nominated subscriber’s discretion.

You can cancel any Player’s subscription at any time in the “Profile” section of each player on the Dashboard.
