UV dose is a thermoregulation and recovery cost that compounds across a training block. These wearables are ranked on how usefully they quantify that load. Skin-ageing claims are not the point.
| What it measures | Verdict | Link | |||
|---|---|---|---|---|---|
| 01 | UV Sensor | UV-A + UV-B index, daily MED, clip-on, app sync. | ~$130 | The veteran clip-on. Reliable cumulative-dose tracking, useful for managing UV as part of overall heat and recovery load across long training blocks. | Check price |
| 02 | My Skin Track UV | Battery-free UV sensor, NFC sync to phone, cumulative dose. | ~$60 | Cheapest credible dose tracker. Verify availability — distribution has been patchy. Performance read: useful if you only need a daily UV-load number. | Check price |
| 03 | Smartwatch UV apps | Indicative UV index via weather APIs, no on-body sensor. | Free | Convenient but inferred, not measured. Fine for a baseline; not adequate for managing UV as a load variable across long outdoor sessions. | Check price |
