# ChatSK vs Tempo

The clearest difference is ads: Tempo at none against ChatSK's shown. ChatSK's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. ChatSK sells 4 in-app purchases, starting at $7.99 per month and Tempo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ChatSK ships an update every 3 weeks, Tempo every 2 months. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
