# Rails World vs LinkUs

Rails World and LinkUs 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. Neither carries in-app purchases, so what you see is what you pay.

Rails World ships an update monthly, LinkUs fortnightly. The most recent releases landed on September 4, 2026 and September 14, 2026 respectively.
