# HR vs SkyMap OnSite

The clearest difference is update cadence: SkyMap OnSite at every 5 months against HR's every 15 months. HR's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

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

HR ships an update every 15 months, SkyMap OnSite every 5 months. The most recent releases landed on May 16, 2026 and September 8, 2026 respectively.
