# Recursive vs PairLock

The clearest difference is price: PairLock at Free against Recursive's $2.99. PairLock also leads on review sentiment (100% vs 71%). Recursive's advantage is ads (none vs shown) and ratings volume (28 vs 2). On rating, update cadence, in-app purchases and device support there is nothing between them.

PairLock is free to download; Recursive costs $2.99 up front. Recursive sells 3 one-off in-app purchases and PairLock sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Recursive against 5.0 for PairLock. That said, the two scores are not equally well evidenced: Recursive has 28 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 71% of Recursive's written reviews are positive against 100% of PairLock's.

Recursive ships an update every 4 days, PairLock every 3 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
