# ScaleClock vs MusicPRO

The clearest difference is rating: ScaleClock at 5.0 against MusicPRO's 4.2. ScaleClock also leads on update cadence (every 8 days vs every 2 weeks). MusicPRO's advantage is ads (none vs shown) and ratings volume (5 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ScaleClock sells 4 in-app purchases, starting at $10.99 per month and MusicPRO sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ScaleClock holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: MusicPRO has 5 ratings behind it against 1, so its average is the more settled of the two.

ScaleClock ships an update every 8 days, MusicPRO every 2 weeks. The most recent releases landed on October 15, 2026 and October 24, 2026 respectively.
