# GraviTrax Power vs Flash Studio

The clearest difference is rating: Flash Studio at 4.8 against GraviTrax Power's 3.7. Flash Studio also leads on update cadence (weekly vs every 10 months) and ratings volume (3.4K vs 6). GraviTrax Power's advantage is ads (none vs shown) and review sentiment (75% vs 56%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Flash Studio holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Flash Studio has 3.4K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 75% of GraviTrax Power's written reviews are positive against 56% of Flash Studio's, so the app with the better star average is not the one people write more warmly about.

GraviTrax Power ships an update every 10 months, Flash Studio weekly. The most recent releases landed on September 15, 2026 and September 26, 2026 respectively.
