# SpaSync vs CarKit

The clearest difference is ads: SpaSync at none against CarKit's shown. CarKit's advantage is update cadence (every 4 days vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. SpaSync sells 2 in-app purchases, starting at $1.99 per month and CarKit sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SpaSync ships an update every 4 months, CarKit every 4 days. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
