The clearest difference is rating: 3D Solar System at 4.4 against BlackHolesHD's 3.4. 3D Solar System also leads on ratings volume (1.7K vs 38). BlackHolesHD's advantage is in-app purchases (none vs 12) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. 3D Solar System sells 12 in-app purchases, starting at $7.99 per 7 days. BlackHolesHD asks for nothing beyond the download.

3D Solar System holds the better App Store score, 4.4 against 3.4.
