# HeightMax vs Standly

The clearest difference is rating: Standly at 4.6 against HeightMax's 3.7. Standly also leads on update cadence (every 3 weeks vs every 8 months) and ratings volume (115 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. HeightMax sells 3 in-app purchases, starting at $4.99 per 7 days and Standly sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Standly holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Standly has 115 ratings behind it against 7, so its average is the more settled of the two.

HeightMax ships an update every 8 months, Standly every 3 weeks. Both last shipped on October 24, 2026.
