# OSM sketch vs OpenMaps

The clearest difference is review sentiment: OSM sketch at 100% against OpenMaps's 10%. OSM sketch also leads on rating (4.5 vs 3.9) and in-app purchases (none vs 2). OpenMaps's advantage is update cadence (every 2 months vs every 4 months) and ratings volume (16 vs 2). On price and ads there is nothing between them.

Both are free to download. OpenMaps sells 2 in-app purchases, starting at $3.99 per month. OSM sketch asks for nothing beyond the download.

OSM sketch holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: OpenMaps has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of OSM sketch's written reviews are positive against 10% of OpenMaps's.
