# AR星座 vs ChemPlay

The clearest difference is ads: ChemPlay at none against AR星座's shown. AR星座's advantage is update cadence (monthly vs every 12 months) and iOS requirement (12.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. AR星座 sells 3 one-off in-app purchases and ChemPlay sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

AR星座 ships an update monthly, ChemPlay every 12 months. The most recent releases landed on October 14, 2026 and October 19, 2026 respectively.
