Verdict
The clearest difference is review sentiment: PDRA Slips at 100% against Race Day Tracker's 56%. PDRA Slips also leads on update cadence (fortnightly vs every 2 months). Race Day Tracker's advantage is rating (4.1 vs 3.7) and ratings volume (38 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Race Day Tracker sells 1 in-app purchase, starting at $9.99 per year and PDRA Slips sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Race Day Tracker holds the better App Store score, 4.1 against 3.7. That said, the two scores are not equally well evidenced: Race Day Tracker has 38 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 56% of Race Day Tracker's written reviews are positive against 100% of PDRA Slips's, so the app with the better star average is not the one people write more warmly about.
Race Day Tracker ships an update every 2 months, PDRA Slips fortnightly. Both last shipped on October 24, 2026.
