Well Rhythm
Read full descriptionHide full description
Well Rhythm is a self-care app for reflecting on how your body and mind feel — alongside the weather (barometric pressure, temperature, humidity and more) and your daily condition and habits. Period tracking is optional — turn it on or off whenever you need. ■ Wellness forecast A gentle take on how to approach today and the next 7 days. The forecast starts from general conditions like barometric pressure and weather, and as your records build up, it gradually reflects your own patterns too. ■ Your own data is the strongest evidence Easily log headaches, mood, symptoms, hydration and medication. The symptoms you record most often appear intuitively as larger circles, drawn from your own history. What's been well confirmed is shown under “Your patterns”; what's still emerging stays under “Your records so far.” Without decoding difficult numbers, you can see at a glance which conditions tended to overlap with your hard days and your calm ones. ■ Make the look and settings your own Tailor how the app works and looks to suit you. Show only the dashboard cards and tracking screens you need, and reorder them freely. Theme, font, text size, contrast, tracked items, notifications and health-data integration are all adjustable. ■ Widgets & Apple Watch Quickly check and log today's forecast, pressure, cycle, hydration and more from your Home Screen or Apple Watch. ■ Partner sharing (optional) Stay quietly close, even when you're apart. Well Rhythm includes a relaxed way to stay connected with someone who matters. With a quiet cheer — a neutral signal that never becomes a burden — you can gently let them know you care. You choose how much to share, and nothing is ever made public to third parties (no personally identifying information is handled, and data is encrypted). ■ Privacy first (local-first) Your raw health, cycle and diary data is never sent to the Well Rhythm cloud or servers. It's stored encrypted on your device. The location used to fetch weather is only a coarse value, rounded to roughly a 1 km square. Key features • Log body and mind symptoms, mood, hydration, medication, basal body temperature, diary and more • A 7-day wellness forecast based on barometric pressure, weather and your own records • A calendar that brings your menstrual cycle and health records together in one place • Graphs and notifications for changes in pressure and humidity, plus basal body temperature, sleep, steps and hydration • A look back at the symptoms you log most and the conditions that tended to overlap with how you felt • Relaxed sharing with someone who matters (a quiet cheer) • Check and log from widgets and Apple Watch The forecasts and patterns shown are self-care guides calculated from overlaps in your records; they do not indicate a cause or a causal relationship. This app supports wellness management and is not intended to diagnose, treat, or prevent any medical condition. If you have severe symptoms or feel anxious, please consult a medical institution.
