# 3DMark vs Watt Charging Speed

The clearest difference is price: 3DMark at Free against Watt Charging Speed's $1.99. 3DMark also leads on review sentiment (53% vs 20%) and ratings volume (86 vs 13). Watt Charging Speed's advantage is update cadence (every 3 weeks vs every 2 months) and chart position (#59 vs unranked). On rating, ads, in-app purchases and device support there is nothing between them.

3DMark is free to download; Watt Charging Speed costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Watt Charging Speed holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: 3DMark has 86 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 53% of 3DMark's written reviews are positive against 20% of Watt Charging Speed's, so the app with the better star average is not the one people write more warmly about.

3DMark ships an update every 2 months, Watt Charging Speed every 3 weeks. The most recent releases landed on October 21, 2026 and October 28, 2026 respectively.
