The clearest difference is review sentiment: Galaxy Map at 80% against BlackHolesHD's 27%. Galaxy Map also leads on rating (4.6 vs 3.4) and ratings volume (600 vs 38). BlackHolesHD's advantage is in-app purchases (none vs 13) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Galaxy Map sells 13 one-off in-app purchases. BlackHolesHD asks for nothing beyond the download.

Galaxy Map holds the better App Store score, 4.6 against 3.4.
