# T vs Cairn

The clearest difference is ads: Cairn at none against T's shown. Cairn also leads on update cadence (every 11 days vs every 10 months). T's advantage is 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. T sells 5 one-off in-app purchases and Cairn sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

T ships an update every 10 months, Cairn every 11 days. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
