Both unlock the same Premium features. The difference is how you pay and what you get:
App store subscriptions (Google Play, Apple, Microsoft) renew automatically and are billed through the store. You handle cancellation through the store. No hardware included.
Bundles (from obdai.app/shop or Amazon) include an OBD-II scanner plus prepaid Premium for 3 or 12 months. They do NOT auto-renew. When your term ends, you’ll have renewal options.
Features are identical; only billing and hardware differ.
