# Polyloop vs SKYLINE

The clearest difference is update cadence: SKYLINE at every 3 weeks against Polyloop's every 6 months. Polyloop's advantage is iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Polyloop sells 10 one-off in-app purchases and SKYLINE sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Polyloop ships an update every 6 months, SKYLINE every 3 weeks. Both last shipped on October 28, 2026.
