Verdict
The clearest difference is ads: Driving Speed HD at none against FlexicX's shown. Driving Speed HD also leads on iOS requirement (8.0 vs 15.0). FlexicX's advantage is review sentiment (88% vs 54%) and update cadence (every 8 days vs every 4 months). On price, in-app purchases and monetization model 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. Driving Speed HD sells 5 one-off in-app purchases and FlexicX sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
FlexicX holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: FlexicX has 12K ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 54% of Driving Speed HD's written reviews are positive against 88% of FlexicX's.
Driving Speed HD ships an update every 4 months, FlexicX every 8 days. Both last shipped on October 25, 2026.
