ExpoDose

Read full description

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. Main features of ExpoDose® - Sensor-less solar exposure monitoring using real-time satellite data, including automatic detection of indoor/outdoor position based on smartphone's sensors (manually editable to further increase accuracy if needed) - Whole-body sun exposure mapping, thanks to the assessment of direct, diffuse and ground-reflected components of sunlight - Solar irradiance assessment in multiple spectral bands and with several photobiological action spectra, including UV-B, UV-A, UV-A1, UV-A2, visible, HEV blue, erythemal-weighted, vitamin D-weighted, photopic-weighted, PpIX-weighted - No periodic calibration needed thanks to Earth Observation satellite imagery and GNSS analytics - Global geographic coverage - Exposure dose updated every 1 minute Real-world scientific validation The satellite-based technology used for ExpoDose® has been validated in collaboration with international institutions, like Public Health England (now UKHSA), NHS Tayside, King's College London, European Space Agency, UK Space Agency, MedCin Dermatology. Several research studies were conducted in real-world conditions around the world in all weather conditions for validating the high accuracy and reliability of this technology, including: - Morelli M et al.

Living with bipolar can feel isolating. Bipolar Anonymous is a safe, anonymous community where you can share what you're really going through and connect with people who understand — because they're living it too. No real names. No profiles to maintain. No judgement. Just honest conversation between people who know what the highs, the lows, and everything in between actually feel like. Why Bipolar Anonymous? • Truly anonymous — pick a nickname and post. There's no public profile, no photo, and nothing tying your words back to you. • A community that understands — share a hard day, a small win, or a question you can't ask anyone else. Read what others are going through and remind yourself you're not alone. • Judgement-free by design — this is a space for support, not advice-giving or criticism. Everyone here is on their own journey. • Simple and calm — no feeds engineered to keep you scrolling, no likes to chase. Just a quiet place to be heard. Who it's for Anyone affected by bipolar disorder — whether you've been diagnosed, you think you might be, or you love someone who has. Wherever you are with it, there's a place for you here. A note on support Bipolar Anonymous is a peer-support community, not a substitute for professional care. It doesn't provide medical advice, diagnosis, or crisis services. If you're in crisis or thinking about harming yourself, please contact your local emergency services or a crisis line right away. Come as you are. Say what you need to say. You're among people who get it. // Built by James Markey MBE and hosted by UNI•SIM \\
