Check current UVI and receive a reminder as UV dose builds up.
AH-Sunuvi shows the current sunlight UVI at your location and gives a beep reminder when the selected UV dose reminder level is reached, helping you know when it is time to check or strengthen your sun protection.
For sunlight UVI awareness and personal UV dose reminder use. Use together with sunscreen, protective clothing and shade.
Stay aware without giving up outdoor time.
Check UVI where you actually are
Weather apps and forecasts are useful, but local conditions can differ with time, cloud and surroundings.
Consider exposure over time
A single UVI reading is only part of the picture. UV dose continues to build while you remain outdoors.
Receive a practical reminder
When the selected UV dose reminder level is reached, AH-Sunuvi beeps so you can check protection, seek shade or reduce further exposure.
Current UVI and time work together.
AH-Sunuvi combines an on-site UVI reading with UV dose awareness over time, helping you decide when to review or strengthen sun protection.
More than a momentary reading
A high UVI does not automatically mean immediate skin injury. Duration of exposure also matters.
Three reminder levels
Choose Low, Medium or High according to your preferred precaution level.
Sunscreen plus a reminder
Sunscreen remains important. AH-Sunuvi complements your routine by reminding you as UV exposure continues to build.
Ready in three straightforward steps.
Measure current outdoor UVI
Place the device where you are spending time outdoors and read the current sunlight UVI.
Select a reminder level
Choose the UV dose reminder level that suits your preferred precaution level.
Listen for the beep
When the selected reminder level is reached, AH-Sunuvi beeps and reminds you to take action.
Forecast UVI can differ from the UVI at your spot.
UV apps and weather forecasts are useful, but local conditions can vary. AH-Sunuvi helps you check the sunlight UVI at your actual location and keeps the UV dose reminder running as time passes.
Enjoy the outdoors with a more informed routine.
AH-Sunuvi does not replace sunscreen, shade, hats or protective clothing. It adds current UVI information and a UV dose reminder to help you decide when to check or strengthen protection.
Place it next to you rather than aiming it at the sun.
When sunbathing or spending time outdoors, place AH-Sunuvi flat beside you. The aim is to measure where your body is, rather than continuously pointing the device directly at the sun.
Clouds and local conditions can change UVI.
UVI may vary during the day. Cloud movement, time and local surroundings can change the measured value, making on-site readings and a continuing UV dose reminder useful.
