# BJLK9 vs Probability

The clearest difference is rating: BJLK9 at 2.8 against Probability's 1.0. BJLK9 also leads on review sentiment (39% vs 0%) and ratings volume (9 vs 1). Probability's advantage is update cadence (every 10 days vs every 6 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. BJLK9 sells 4 one-off in-app purchases and Probability sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

BJLK9 holds the better App Store score, 2.8 against 1.0. That said, the two scores are not equally well evidenced: BJLK9 has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 39% of BJLK9's written reviews are positive against 0% of Probability's.

BJLK9 ships an update every 6 weeks, Probability every 10 days. The most recent releases landed on August 7, 2026 and September 4, 2026 respectively.
