# OSM sketch vs Map Stretch

The clearest difference is ads: Map Stretch at none against OSM sketch's shown. Map Stretch also leads on update cadence (every 5 days vs every 4 months) and monetization model (free vs ad-supported). OSM sketch's advantage is review sentiment (100% vs 78%) and rating (4.5 vs 4.2). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

OSM sketch holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Map Stretch has 10 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 78% of Map Stretch's.

OSM sketch ships an update every 4 months, Map Stretch every 5 days. The most recent releases landed on September 19, 2026 and October 17, 2026 respectively.
