Verdict
GraviTrax and Bold Attack both sit at 4.4 stars, but that hides the real split: 74% of GraviTrax's written reviews are positive against 19% of Bold Attack's. GraviTrax also leads on ads (none vs shown). Bold Attack's advantage is update cadence (daily vs every 5 months). On price, rating, ratings volume 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. GraviTrax sells 1 one-off in-app purchase and Bold Attack sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Bold Attack holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 148 and 418 respectively. Written reviews complicate that: 74% of GraviTrax's written reviews are positive against 19% of Bold Attack's, so the app with the better star average is not the one people write more warmly about.
GraviTrax ships an update every 5 months, Bold Attack daily. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
