Our verdict on Starmap
Starmap is an astronomy atlas for casual and experienced sky observers who want a detailed chart and reference tools on iOS or macOS. The chart aligns with the device’s compass and orientation, while on-device catalogs include 2.5 million stars and 24,000 deep-sky objects. Cross-catalogue search and SIMBAD lookups help with finding objects; dark, red, and daylight themes support different observing conditions. Its offline catalogs make it useful when an internet connection is unavailable, though some data is live and fetched from external services.
Equipment tools are a central strength for observers planning what they can see through their own kit. Starmap lets users configure telescopes, eyepieces, cameras, finders, and binoculars, then calculate field of view. Telrad rings and reticles provide additional chart references. The app also includes solar-system object information, live small-body data from the Minor Planet Center, and solar activity and space-weather data from NOAA. Integrations with SIMBAD, NOAA Space Weather Prediction Center, Minor Planet Center, and iCal give it a reference-data focus rather than a telescope-control role.
According to the vendor, Starmap is free, with no advertising, subscription, or in-app purchases advertised on its current site. It is limited to iOS and macOS, so observers on other platforms will need an alternative. It also does not control telescopes, making it a poor fit for buyers seeking an app that directs a mount. For iOS observers who value detailed charts, offline catalogs, and equipment field-of-view calculations, its free offering covers a broad set of planning and reference needs; those who need telescope control or broader platform support should look elsewhere.
