How has your wrist temperature changed over the past nights? Wrist Temperature Tracker shows your Apple Watch readings as history, comparisons and widgets. For people with a compatible Watch who want a clearer view of their overnight data in Apple Health. The app does not take measurements and is not an on-demand thermometer. Try the iPhone app for six days after installation. Continued access then requires a monthly subscription, annual subscription, or one-time purchase. You can restore an existing purchase. Before you start - You need an Apple Watch that supports wrist temperature sensing. - Wear it while sleeping. Track Sleep with Apple Watch and Sleep Focus need to be active for at least 4 hours per night. - After setup or pairing, establishing a baseline usually takes about 5 nights. - Allow the app to read wrist temperature from Health. If Health has no samples, the app cannot show any values. Features - Optional import of recorded cycle starts from Apple Health, with separate read permission. Recorded starts and temperature-based estimates are clearly distinguished. Reproductive data stays on your device; the app does not write cycle entries to Health. - Recorded night readings plus weekly, monthly, and yearly trends - Heat maps that show changes from your usual pattern - Cycle comparisons and temperature context for spotting recurring patterns - Widgets and complications for quick access to recent data - Get notified when a new reading arrives: all readings, or only values below or above your absolute temperature thresholds. No on-demand measurement or guaranteed daily notification. - A diagnostics area for Health data, notifications, and purchases Cycle insights help you recognize personal patterns. They are not intended for contraception and do not replace a medical thermometer or diagnosis. Terms and conditions: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Busy days, different places, changing routines. Your body responds to all of them. Tensi helps you see how your everyday life relates to your stress and recovery. It brings together Apple Health data, your calendar, places you visit and weather conditions to find patterns in your own measurements. UNDERSTAND YOUR DAY See how your heart rate variability (HRV) and resting heart rate compare with your personal range. Get a clear picture of today's readings alongside recent recovery trends, so one unusual measurement doesn't tell the whole story. FIND PATTERNS IN YOUR LIFE Are meeting-heavy days followed by lower HRV? Do your measurements change on days you visit certain places? Is there a connection between the weather, your activity and your sleep? Tensi looks for these relationships over time. Each finding includes the supporting data and a plain-language explanation of what it may mean. GO BEYOND A SINGLE NUMBER Explore both RMSSD and SDNN, two measures of HRV, alongside resting heart rate, sleep, activity and other supported health data. Detailed charts help you understand changes in the context of your usual patterns. LOOK BACK AND SEE WHAT CHANGED Browse previous days and weekly reports to compare your schedule, health measurements and recovery. Notice recurring patterns that can be easy to miss day to day. KEEP IT CLOSE WITH APPLE WATCH Check your daily overview, key measurements, meeting load and personal patterns from your wrist. iPhone and Apple Watch widgets keep useful information within easy reach. Tensi is designed to help you understand your data without turning your day into another tracking task. Available insights depend on the data recorded and the permissions you enable. Some features require Tensi Pro. Tensi is a wellness app, not a medical device. HRV can reflect physical strain and recovery, but it does not directly measure mental stress. Patterns show associations, not proof of cause and effect. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
