# Santa vs Einstein's Relativity

The clearest difference is ads: Einstein's Relativity at none against Santa's shown. Santa's advantage is update cadence (every 12 months vs every 24 months) and iOS requirement (11.1 vs 13.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Santa sells 1 one-off in-app purchase and Einstein's Relativity sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Santa ships an update every 12 months, Einstein's Relativity every 24 months. The most recent releases landed on September 11, 2026 and February 21, 2026 respectively.
