# Bluejacketeer vs FindSpeedCalculator

The clearest difference is in-app purchases: FindSpeedCalculator at none against Bluejacketeer's 1. Bluejacketeer's advantage is ratings volume (389 vs 1) and update cadence (fortnightly vs every 2 months). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Bluejacketeer sells 1 in-app purchase, starting at $24.99 per month. FindSpeedCalculator asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 3.9 for Bluejacketeer against 4.0 for FindSpeedCalculator. That said, the two scores are not equally well evidenced: Bluejacketeer has 389 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 55% of Bluejacketeer's written reviews are positive against 50% of FindSpeedCalculator's.

Bluejacketeer ships an update fortnightly, FindSpeedCalculator every 2 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
