# Fast Tracker vs Prime

Fast Tracker and Prime both sit at 4.7 stars, but that hides the real split: 86% of Fast Tracker's written reviews are positive against 43% of Prime's. Prime's advantage is ratings volume (4.6K vs 431). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Fast Tracker sells 1 in-app purchase, starting at $2.99 per month and Prime sells 10 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Fast Tracker against 4.6 for Prime. That said, the two scores are not equally well evidenced: Prime has 4.6K ratings behind it against 431, so its average is the more settled of the two. Written reviews are what separate them: 86% of Fast Tracker's written reviews are positive against 43% of Prime's.

Fast Tracker ships an update monthly, Prime every 3 weeks. The most recent releases landed on October 25, 2026 and October 29, 2026 respectively.
