Verdict
The clearest difference is review sentiment: UCA at 100% against Probability Distribution's 33%. UCA also leads on in-app purchases (none vs 1). Probability Distribution's advantage is rating (4.5 vs 3.0) and ratings volume (17 vs 2). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Probability Distribution sells 1 one-off in-app purchase. UCA asks for nothing beyond the download.
Probability Distribution holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Probability Distribution has 17 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of UCA's written reviews are positive against 33% of Probability Distribution's, so the app with the better star average is not the one people write more warmly about.
UCA ships an update every 3 weeks, Probability Distribution every 2 weeks. Both last shipped on November 3, 2026.
