# Speedometer vs SpeedX

The clearest difference is rating: Speedometer at 4.6 against SpeedX's 4.0. Speedometer also leads on ratings volume (110 vs 5) and review sentiment (100% vs 89%). SpeedX's advantage is update cadence (every 4 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Speedometer sells 1 one-off in-app purchase and SpeedX sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Speedometer holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Speedometer has 110 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 100% of Speedometer's written reviews are positive against 89% of SpeedX's.

Speedometer ships an update every 3 months, SpeedX every 4 weeks. The most recent releases landed on October 21, 2026 and October 6, 2026 respectively.
