# Engine Link LE vs FastR

The clearest difference is rating: FastR at 4.4 against Engine Link LE's 3.2. FastR also leads on ratings volume (290 vs 12). Engine Link LE's advantage is in-app purchases (none vs 2) and review sentiment (46% vs 38%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. FastR sells 2 one-off in-app purchases. Engine Link LE asks for nothing beyond the download.

FastR holds the better App Store score, 4.4 against 3.2. That said, the two scores are not equally well evidenced: FastR has 290 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 46% of Engine Link LE's written reviews are positive against 38% of FastR's, so the app with the better star average is not the one people write more warmly about.

Engine Link LE ships an update every 6 months, FastR every 5 months. The most recent releases landed on October 10, 2026 and October 15, 2026 respectively.
