# Probability Distribution vs IngenieriaTracker

The clearest difference is review sentiment: IngenieriaTracker at 83% against Probability Distribution's 33%. IngenieriaTracker also leads on in-app purchases (none vs 1) and update cadence (every 2 days vs every 2 weeks). Probability Distribution's advantage is rating (4.5 vs 1.0) and ratings volume (15 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Probability Distribution sells 1 one-off in-app purchase. IngenieriaTracker asks for nothing beyond the download.

Probability Distribution holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Probability Distribution has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of Probability Distribution's written reviews are positive against 83% of IngenieriaTracker's, so the app with the better star average is not the one people write more warmly about.

Probability Distribution ships an update every 2 weeks, IngenieriaTracker every 2 days. The most recent releases landed on September 9, 2026 and September 19, 2026 respectively.
