Understand your physiological stress and recovery patterns with signals from Apple Watch. Tensly uses heart rate, heart rate variability (HRV), sleep, activity, and workout context to learn your normal patterns and show how your current signals compare. Instead of asking you to log every mood, Tensly works quietly with the HealthKit data already available on your devices. PERSONAL TO YOU Tensly builds an adaptive baseline from available HealthKit history and continues learning as new readings arrive. Because wearable data can be intermittent, Tensly only estimates a current state when it has enough recent evidence. When it does not, it clearly shows Monitoring rather than presenting uncertain results. AT A GLANCE โ€ข See your current wellness state as Good, Busy, Stressed, or Overwhelmed โ€ข Understand whether your signals are within or above your personal range โ€ข View relevant heart rate, HRV, sleep, and activity context โ€ข Follow your state history without complicated charts โ€ข Receive optional, gentle reminders when a pause may help GUIDED BREATHING Use a calm visual breathing guide that adapts its pacing to your current context. When a fresh physiological signal is available, Tensly can recognize an improving response. Otherwise, the session completes without claiming recovery and monitoring continues in the background. DESIGNED FOR PRIVACY Your physiological information is processed locally using Apple HealthKit and stored on your device. No account is required, and Tensly does not transmit your HealthKit readings to its own server. REQUIREMENTS Requires an iPhone with iOS 26 or later and an Apple Watch with watchOS 26 or later. Apple Watch must be worn regularly and Health access must be enabled for useful readings. The frequency of HRV readings is controlled by Apple Watch and may vary. Tensly is a general wellness tool, not a medical device. It does not diagnose, treat, cure, or prevent any medical condition. Contact a qualified healthcare professional for medical concerns.

Most acid reflux advice hands you a list of 40 foods to avoid. AcidLog does the opposite: it finds the 3 or 4 that actually bother YOU โ€” so you can stop fearing the rest. Log a meal and how you felt in about 30 seconds. AcidLog's correlation engine connects what you ate to your symptoms and, within 14 days, gives you a personal trigger list ranked by confidence. WHY A GENERIC "AVOID THESE FOODS" LIST FAILS Coffee wrecks one person and does nothing to the next. Reflux is personal. Instead of eliminating everything, AcidLog watches your own meals and symptoms and surfaces the patterns that are actually yours. HOW IT WORKS 1. Log โ€” add a meal and rate symptoms (heartburn, regurgitation, throat, cough, bloating) in seconds. 2. Correlate โ€” the on-device engine links foods to the symptoms that followed. 3. Discover โ€” by day 14 you get a ranked list of your likely triggers, with a confidence score for each. WHAT'S FREE The full 14-day trigger discovery is free: log meals and symptoms and see your first correlations and trigger list. No trial paywall in front of the core. ACIDLOG PRO (monthly or annual subscription) - Unlimited history and correlation beyond day 14 - Doctor-ready PDF report to bring to your gastroenterologist - Trend stats over weeks and months - Ongoing trigger refinement as your diet changes BUILT FOR REAL LIFE - Offline logging โ€” entries queue on your phone and sync when you're back online - No ads. Ever. - Fast enough to log at the table, not an hour later - Works for GERD, silent reflux / LPR, and post-meal indigestion MADE FOR - Adults with GERD or silent reflux (LPR), including long-term PPI users who want their own triggers, not another handout - Anyone newly diagnosed and told to "keep a food diary" - Caregivers who cook and want to know which meals set off symptoms AN HONEST NOTE AcidLog is a diary and correlation tool, not a medical device. It does not diagnose, treat, or cure any condition, and it isn't a substitute for your doctor. Its job is to hand you and your clinician better data. Find your triggers, keep your food. Start free.
