# LK vs SonoBus

The clearest difference is in-app purchases: SonoBus at none against LK's 8. SonoBus also leads on rating (4.5 vs 4.3) and iOS requirement (15.0 vs 17.0). LK's advantage is ratings volume (706 vs 41) and update cadence (fortnightly vs every 6 weeks). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. LK sells 8 one-off in-app purchases. SonoBus asks for nothing beyond the download.

SonoBus holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: LK has 706 ratings behind it against 41, so its average is the more settled of the two. Written reviews point the same way: 64% of LK's written reviews are positive against 68% of SonoBus's.

LK ships an update fortnightly, SonoBus every 6 weeks. Both last shipped on September 23, 2026.
