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. Keep On Line sells 9 one-off in-app purchases and Ultimate Racing 2D 2! sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Ultimate Racing 2D 2! holds the better App Store score, 4.4 against 3.9. Both are backed by a comparable volume of ratings — 55 and 189 respectively. Written reviews complicate that: 80% of Keep On Line's written reviews are positive against 76% of Ultimate Racing 2D 2!'s, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
