# ScaleClock vs Hearing

The clearest difference is in-app purchases: Hearing at none against ScaleClock's 4. Hearing also leads on ratings volume (119 vs 1) and iOS requirement (12.0 vs 15.5). ScaleClock's advantage is update cadence (every 5 days vs every 6 months) and rating (5.0 vs 4.6). On price, ads 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. Hearing asks for nothing beyond the download.

ScaleClock holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Hearing has 119 ratings behind it against 1, so its average is the more settled of the two.

ScaleClock ships an update every 5 days, Hearing every 6 months. The most recent releases landed on August 29, 2026 and September 18, 2026 respectively.
