ExpoDose vs Vitamin D Sun Tracker

ExpoDose® is a smart dosimeter for the automatic assessment of personal sun exposure in everyday life. It doesn't need any solar sensors or wearable devices, just the smartphone that can be even kept in a purse or pocket. You can find more information in a short YouTube video https://www.youtube.com/watch?v=iObUwhCb-24 and at https://www.expodose.com. It can be used: - to self-monitor your personal daily sun exposure in everyday life; - and/or to support your participation in clinical / research studies (e.g. about sun exposure-related lifestyle, sunscreen use, outdoor workers' risk assessment, skin diseases management/prevention). The app is based on the siHealth’s HappySun® patented technology for the satellite-based monitoring of solar radiation, anywhere and anytime (https://www.happysun.co.uk). Use of the app The ExpoDose® app automatically tracks your sun exposure during daytime as long as the smartphone is connected to internet and the app is kept active in background. In particular, the app automatically detects whenever you are outdoor and tracks the incident spectral solar radiation you accumulate on your body, in multiple spectral bands (eg UV-B, UV-A, erythemal) and on multiple body sites (scalp, face, shoulders). In case you wish to do so, you can share your monitored sun exposure with a clinical / research institution having an active ExpoDose® license. In that case, you'll need to log into the app with a specific "access code" that will be provided to you by the clinical / research institution (e.g. if you are a participant in a clinical trial or research study), and the institution's staff will be able to see your accumulated sun exposure data via a dedicated web-portal. Please contact us at support@expodose.com or visit https://www.expodose.com to receive more information about how to activate an ExpoDose® license for research / clinical institutions.
