# AppBlock vs RustSync

The clearest difference is ads: RustSync at none against AppBlock's shown. RustSync also leads on iOS requirement (15.0 vs 17.0). AppBlock's advantage is update cadence (weekly vs every 3 weeks) and chart position (#188 vs unranked). On price, in-app purchases and device support there is nothing between them.

Both are free to download. AppBlock sells 10 in-app purchases, starting at $4.99 per month and RustSync sells 4 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

AppBlock ships an update weekly, RustSync every 3 weeks. The most recent releases landed on October 12, 2026 and October 1, 2026 respectively.
