ExpoDose vs Heart Alert

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.

Heart Alert connects to your Bluetooth heart rate chest strap, armband or watch and plays a sound the moment your BPM goes above or below the range you set. Choose a minimum and a maximum, put your phone away, and train by ear. No screen-watching. No zone math. No account. HOW IT WORKS 1. Put on your chest strap or armband, or turn on heart rate broadcast on your watch. 2. Set your min and max BPM. 3. Press start — you get an alert when you drift too high or too low, and another one when you are back in range. FEATURES – Custom minimum and maximum BPM limits – High heart rate alerts and low heart rate alerts – Immediate audio alerts, with adjustable volume – Optional vibration – Repeat interval of 1, 3, 5 or 10 seconds while you are out of range – "Out of range for" delay, so a short spike or a passing dip stays quiet – Initial delay, to keep things silent during your warm-up – Sensor battery level at a glance – Runs in the background and with the screen locked – Available in 24 languages, spoken alerts included – Fast setup, nothing to sign up for WORKS WITH YOUR CHEST STRAP Heart Alert is built for Bluetooth Low Energy (BLE) heart rate chest straps, including: – Polar H10, Polar H9, Polar H7 – Garmin HRM 600, HRM 200, HRM-Pro Plus, HRM-Pro, HRM-Fit, HRM-Dual – Wahoo TRACKR Heart Rate, TICKR, TICKR X – CooSpo H6, H808S, H9Z – Magene H64, H303 – Suunto Smart Heart Rate Belt – Decathlon Kiprun / Kalenji Dual HRM belt – iGPSPORT HR40, Moofit, XOSS, Bryton, Sigma and other generic BLE chest straps ARMBANDS AND WATCHES TOO – Armbands: Polar Verity Sense, Polar OH1, Scosche Rhythm, Wahoo TICKR FIT, CooSpo HW807 – Watches that broadcast heart rate over Bluetooth: Garmin (Broadcast Heart Rate), Polar (share HR with other devices), Coros, Suunto, Amazfit, Huawei, Xiaomi Smart Band, Whoop Turn on heart rate broadcast on your watch before you scan. Apple Watch and Fitbit do not broadcast heart rate over Bluetooth, so they cannot connect. Any device that sends a standard Bluetooth LE heart rate signal should work, though Bluetooth on its own does not guarantee compatibility, and ANT+-only sensors will not connect. If yours is not detected, send the developer a message. An external heart rate sensor is required. Camera-based measurement is not supported. MADE FOR – Zone 2 work and aerobic base building – Running, cycling and indoor cycling – Cardio, gym sessions and interval training – Endurance and steady-state efforts – Easy recovery days, where the whole point is keeping the effort down – Anyone who wants a heart rate alarm and nothing else WHY AN ALARM INSTEAD OF A DISPLAY? A number on a screen only helps if you look at it. An alert means your target range takes care of itself, and you only think about it when something actually needs attention — on the treadmill, on the road, or with your phone in a jersey pocket. PRICING Your first 5 tracking sessions are free. Unlimited tracking is a one-time purchase. No subscription, no ads. PRIVACY Heart Alert collects no data. Your heart rate never leaves your phone. BACKGROUND USE Heart Alert keeps tracking in the background and with the screen locked. Don't close it from the app switcher while you train: iOS stops the app, and the alerts with it. Heart Alert is a fitness and training tool. It is not a medical device, it is not intended to diagnose, treat, cure or prevent any disease, and it should not be relied on for emergency or continuous health monitoring. Check with a doctor if you have questions about your heart rate or your training.
