Field notes
The homepage says catalog entries draw on data from the NASA Exoplanet Archive, and offers side-by-side comparison of up to three worlds using size, mass, temperature, orbit, and distance. It describes saved favorites, exploration stamps, and personal notes as offline features; those functions are presented on the site but the app itself is not shown in the supplied evidence.
