# Sail Buddy vs MOB

The clearest difference is rating: MOB at 5.0 against Sail Buddy's 4.4. MOB also leads on update cadence (every 4 days vs every 6 months) and price ($1.99 vs $4.99). Sail Buddy's advantage is ratings volume (14 vs 1) and chart position (#135 vs unranked). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

Sail Buddy costs $4.99 and MOB $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

MOB holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Sail Buddy has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Sail Buddy ships an update every 6 months, MOB every 4 days. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
