About UV GO

UV GO compares daylight outings today and tomorrow using hourly UV and weather forecasts, your free time, duration and activity.

Who makes UV GO

UV GO is designed and built by Artem Bakulin. You can inspect the implementation and report problems in the public GitHub repository. Please avoid posting personal information in public issues.

Data and recommendations

Weather forecasts and city search come from Open-Meteo. UV GO applies its own fixed scoring rules to that forecast. A recommended window is a comparison of the available options, not a guarantee of safe conditions.

Read how the scoring works, including rounding, missing data and the limits of the forecast.

Editorial approach

Our educational guides link to their sources and display their last update date. Health information is based on the referenced public guidance; the outing score is a product rule, not a clinical assessment. No medical reviewer is credited for these guides.

Check the linked sources for their full context. UV GO gives general guidance, not medical advice. Discuss personal health concerns with a healthcare professional.
