# TrailLink vs SYNC

TrailLink and SYNC are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. TrailLink sells 2 one-off in-app purchases and SYNC sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

TrailLink ships an update every 6 weeks, SYNC every 5 weeks. The most recent releases landed on November 5, 2026 and November 10, 2026 respectively.
