# Planet Fun vs Sky Map

The clearest difference is in-app purchases: Planet Fun at none against Sky Map's 4. Planet Fun also leads on rating (4.8 vs 4.4) and device support (3 vs 1). Sky Map's advantage is update cadence (weekly vs every 4 weeks) and ratings volume (46 vs 8). On price and ads there is nothing between them.

Both are free to download. Sky Map sells 4 in-app purchases, starting at $9.99 per 7 days. Planet Fun asks for nothing beyond the download.

Planet Fun holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Sky Map has 46 ratings behind it against 8, so its average is the more settled of the two.
