Key differences
- Face scan vs chat coach: SunRay's AI face scan runs at onboarding and generates a fixed plan. Tan AI's chat coach is an ongoing interface — it retains skin type, stated goals, and session history across conversations.
- Installed base: Tan AI has 2,700+ App Store ratings, SunRay ~300. The Fitzpatrick quiz is deterministic — same inputs, same output. Face-scan output depends on lighting, angle, and image quality at scan time.
- Platform and pricing: Tan AI is on both iOS and Android with a free tier that includes the chat coach, skin quiz, UV tracker, and session timer. SunRay is iOS-only, with pricing at the higher end of the category band.
