# HDL On vs SkyThings

The clearest difference is rating: HDL On at 3.2 against SkyThings's 1.0. HDL On also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (9 vs 1). SkyThings's advantage is review sentiment (25% vs 14%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

HDL On holds the better App Store score, 3.2 against 1.0. That said, the two scores are not equally well evidenced: HDL On has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 14% of HDL On's written reviews are positive against 25% of SkyThings's, so the app with the better star average is not the one people write more warmly about.

HDL On ships an update every 2 weeks, SkyThings every 2 months. The most recent releases landed on July 17, 2026 and September 19, 2026 respectively.
