Amazing cosmic microwave background all-sky maps on your iPhone and iPad! This app allows you to see and compare different generations of CMB fluctuations. It includes 4K resolution all-sky COBE/WMAP/Planck CMB maps and allows you to zoom in and scroll around for map details. You can choose to view a single map, or compare multiple maps by tilting your device. A sky reference map is also included to show the galactic coordinates, notable Milky Way components, and microwave point sources. Cosmic Microwave Background (CMB) is the afterglow radiation from the Big Bang. Its temperature is extremely uniform, but with tiny fluctuations as you will see in these maps. 

In 1992, COBE satellite made the first detection of the CMB fluctuations. The following WMAP and Planck mission were able to scan the sky at better and better resolution. The successes of these CMB observations have provided us great understanding of the Universe over the last decades.

Verdict

The call

The clearest difference is price: CMB Maps at Free against Univerzoom 3D's $2.99. CMB Maps also leads on iOS requirement (6.0 vs 15.0). Univerzoom 3D's advantage is rating (4.8 vs 4.0) and review sentiment (97% vs 67%). On ads, in-app purchases, monetization model and device support there is nothing between them.
