Verdict

The call

The clearest difference is ads: Reaction Time at none against Sky Stack's shown. Reaction Time also leads on device support (5 vs 2). On price, in-app purchases and iOS requirement there is nothing between them.

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