Rainbow Seeker is an iPhone application developed by Ajnaware Pty Ltd, available for free in the Travel & Navigation category. This innovative app utilizes Augmented Reality to inform users of the possibility of spotting rainbows in real-time. By considering the time of day and solar elevation, Rainbow Seeker determines if rainbows are currently feasible. Through precise solar calculations and 3-D trigonometry, the app overlays the expected location of a rainbow onto your camera view. Additionally, Rainbow Seeker offers a comprehensive explanation of rainbows and how the application functions.

Rainbow Seeker stands out for its ad-free and information privacy-focused approach, as it contains no in-app purchases, does not gather user data, and avoids third-party advertisements. Users are encouraged to explore other apps by the developer through in-app links, appreciating the support of their audience.
