Verdict
The clearest difference is review sentiment: Flash Tree at 100% against Race Stats's 40%. Flash Tree also leads on iOS requirement (11.0 vs 16.4). Race Stats's advantage is rating (4.5 vs 4.0) and ratings volume (642 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Race Stats sells 2 in-app purchases, starting at $1.99 per month and Flash Tree sells 1 in-app purchase, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Race Stats holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Race Stats has 642 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 40% of Race Stats's written reviews are positive against 100% of Flash Tree's, so the app with the better star average is not the one people write more warmly about.
Race Stats ships an update every 8 days, Flash Tree every 10 days. The most recent releases landed on October 19, 2026 and October 12, 2026 respectively.
