# 1km vs 시소

The clearest difference is ads: 시소 at none against 1km's shown. 1km's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. 1km sells 11 in-app purchases, starting at $4.99 per month and 시소 sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

1km ships an update every 3 weeks, 시소 every 2 weeks. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
