# Bosc vs StrikeMaster

The clearest difference is ads: StrikeMaster at none against Bosc's shown. StrikeMaster also leads on device support (3 vs 1). Bosc's advantage is ratings volume (483 vs 61) and iOS requirement (16.4 vs 18.0). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Bosc sells 4 in-app purchases, starting at $4.99 per month and StrikeMaster sells 5 in-app purchases, starting at $2.99 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 — 4.8 for Bosc against 4.9 for StrikeMaster. That said, the two scores are not equally well evidenced: Bosc has 483 ratings behind it against 61, so its average is the more settled of the two. Written reviews split almost evenly too, at 90% and 90% positive.

Bosc ships an update every 5 days, StrikeMaster every 8 days. The most recent releases landed on September 26, 2026 and September 24, 2026 respectively.
