There are four levels. Spark is free: look around, read the Community, and enjoy Roy's public teaching. The paid memberships all unlock the whole app and differ by how you pay and the welcome gift: Glow (monthly), Radiance (annual, the best value, save versus paying monthly), and Luminary (lifetime, one payment and it is yours forever). See newnei.com/membership for the current prices.
