Verdict

The call

The clearest difference is rating: MultiTracks.com ChartBuilder at 4.8 against MXBus's 4.2. MultiTracks.com ChartBuilder also leads on ratings volume (6K vs 120) and chart position (#121 vs unranked). MXBus's advantage is monetization model (free with in-app purchases vs subscription). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. MultiTracks.com ChartBuilder sells 4 in-app purchases, starting at $2.99 per month and MXBus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

MultiTracks.com ChartBuilder holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: MultiTracks.com ChartBuilder has 6K ratings behind it against 120, so its average is the more settled of the two. Written reviews complicate that: 63% of MultiTracks.com ChartBuilder's written reviews are positive against 70% of MXBus's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 9, 2026 and October 10, 2026 respectively.
