# GridLinx vs 5th Invention

GridLinx and 5th Invention are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support 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. GridLinx sells 6 one-off in-app purchases and 5th Invention sells 12 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
