TgForce 3D vs RayDay

Note: To use this App, you will need a TgForce 3D impact sensor and iOS 11.0 or later. The new TgForce 3D provides real-time measurement and feedback of impact level while running. With the companion sensor attached to the tibia, the TgForce 3D App evaluates the acceleration level of all axes (X, Y, Z, and 3D Vector). It can be used for monitoring impact while running and evaluate ground reaction forces. These features are helpful for gait retraining or transitioning to a new type of shoes. Features: -Real-time feedback (Visual and Audio) of 3D impact magnitude while running -The new sensor is smaller and lighter than the previous version -Display 3D (Vector) acceleration or single axis (X, Y or Z) ) -Run with or without the phone. The App can retrieve running data stored in the sensor. -Export data on iCloud Drive for further analysis -Set maximum impact level (gMax) -Detailed impact level chart for each running session -Proven direct correlation with ground reaction forces

I built RayDay after years of working indoors left me Vitamin D deficient. The fix wasn't another bottle of pills. It was knowing exactly when the sun was high enough so my body could make Vitamin D the way it always has: naturally, on its own. That's all RayDay does: it tells you your daily sun window, personalized to where you live and your skin type, so you can get Vitamin D the way your body was built to. FEATURES: • D-Window Calculator: know exactly when Vitamin D production is possible today and tomorrow • Live Solar Path: a beautiful animated arc showing the sun's position, sunrise, sunset, and the highlighted D-Window • 7-Day Forecast: see your D-Window for the coming week • Skin Type Personalization: your Fitzpatrick type determines how fast you make Vitamin D • Smart Notifications: get alerted before optimal sun days, plus a heads-up when winter's first D-Window returns • Atmospheric Data: real-time UV index, cloud cover, humidity, and altitude • Phase-Aware Design: app colors shift with the time of day. Dawn, daytime, sunset, and night • Home Screen Widget: a quick glance at your D-Window status • Works Worldwide: accurate for any latitude, including polar regions HOW IT WORKS: RayDay uses NOAA solar position algorithms to calculate the sun's altitude throughout the day. When the sun crosses 35° above the horizon, UVB rays penetrate the atmosphere. That's your D-Window for Vitamin D synthesis. The app factors in your Fitzpatrick skin type to recommend exposure durations that hit your daily IU goal without overexposure. Some features require a paid subscription.
