GBIF, https://www.gbif.org/ https://www.gbif.org/, aggregates biodiversity occurrence data (observations, where specimens held in museums are from, etc). Everything is available through an open API, although we don't index threat status. Perhaps we should. Example: Ceratotherium simum, Southern White Rhinoceros [1]. (The threat status shown on the page is taken from an IUCN API.) The distribution data is available either as individual occurrence records [2], or as a summarized map vector tile [3], or a PNG map tile [4]. You would probably want to add a year range filter for recent observations. You can also download e.g. everything with coordinates and crunch through the data yourself. You will often find the coordinates have a low accuracy for endangered species, to prevent misuse. I won't comment on whether making such an app is a good idea or not.
