# Lock Learn vs LockVocab

Lock Learn and LockVocab 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. Lock Learn sells 1 one-off in-app purchase and LockVocab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Lock Learn ships an update every 2 days, LockVocab every 3 days. The most recent releases landed on October 19, 2026 and October 25, 2026 respectively.
