# InchUp vs HeightPal

The clearest difference is rating: HeightPal at 5.0 against InchUp's 1.0. HeightPal also leads on update cadence (fortnightly vs every 3 months) and ratings volume (6 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. InchUp sells 2 in-app purchases, starting at $6.99 per 7 days and HeightPal sells 5 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

HeightPal holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: HeightPal has 6 ratings behind it against 1, so its average is the more settled of the two.

InchUp ships an update every 3 months, HeightPal fortnightly. The most recent releases landed on October 28, 2026 and October 31, 2026 respectively.
