Ephemeris is a sun, moon, and Milky Way tracking and photography planning app from Vito Technology, positioned as a tool for outdoor and astrophotography. It is not a typical generative AI app; instead, it focuses on astronomical calculations and photography lighting windows to help users plan shoots for any location and date.
Based on the source content, Ephemeris centers on accurately displaying the paths of the sun, moon, and Milky Way, while predicting time windows such as sunrise and sunset, golden hour, blue hour, and civil/nautical/astronomical twilight. It also provides data such as altitude, azimuth, shadow ratio, moon illumination, and moon phase. The AR live view is one of its more valuable features, allowing users on location to view the projected positions of celestial bodies in the sky through augmented reality, helping with composition and timing. The calculator, time machine, reminders, and moon calendar support pre-shoot date selection, timing decisions, and avoiding missed opportunities.
The crawled source text does not provide specific pricing, subscription model, free quota, or trial information. The only related clue is a user comment saying it is “not as expensive as other astronomy software,” but this cannot replace official pricing details. Users still need to confirm the purchase cost on the official website or in the app store.
Its main advantage is its highly focused use case: for landscape, sun/moon, and Milky Way photographers, sun/moon direction, moon phase, golden hour, and AR preview are all frequently needed features. User comments also mention good visuals and beginner-friendliness. The downside is limited disclosure: there is no clear information on Chinese language support, privacy policy, location data handling, offline capability, platform versions, API integration, or the stated accuracy of its algorithms. It also does not explain how real-world factors such as weather and terrain obstruction are handled. For the “AI app/tool” category, it lacks any clearly defined AI model or auto-generation capability.
Ephemeris is suitable for users who regularly plan outdoor photography, astrophotography, Milky Way shoots, and sunrise/sunset shooting locations. If you only need everyday weather checks or simple sunset times, it may be more specialized than necessary. The source text does not mention access from China, so network connectivity, app store availability, and payment methods are all unknown. Users may also want to consider local weather/map tools or other photography ephemeris apps as alternatives.
