# PolyTrak vs French21

PolyTrak and French21 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. PolyTrak sells 2 in-app purchases, starting at $1.99 per month and French21 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on November 4, 2026 and October 28, 2026 respectively.
