Track pelvic and urinary symptoms, spot potential triggers, and bring a clearer symptom history to appointments. Intero is built for symptoms that change, flare up, and get hard to explain when the details are scattered across memory, notes, and spreadsheets. Start with one daily score. Talk or type what changed. Over time, Intero helps make symptoms that keep coming back easier to understand and explain. No account required. Intero does not store your symptom or Apple Health data on its servers. BUILT FOR PELVIC, BLADDER, AND URINARY SYMPTOMS You do not need a formal diagnosis to use Intero. Intero can help you keep a clearer history of: • Endometriosis-related symptoms • Interstitial cystitis and bladder pain • Overactive bladder, urgency, and frequency • CPPS and prostatitis • Pelvic floor dysfunction • Pressure, burning, flare-ups, and symptoms that keep coming back TRACK WITHOUT TURNING LIFE INTO HOMEWORK • Check in once a day in under 10 seconds • Talk or type what you have been up to and how you feel • Log symptom scores, pain, and urgency • Connect Apple Health for sleep, movement, heart rate, workouts, and cycle timing • Review your symptom history over time SEE WHAT HAPPENED BEFORE FLARE-UPS Pelvic and urinary symptoms do not always line up neatly with what happened that same day. Sleep, stress, sitting, food, activity, cycle timing, and workouts can show up before symptoms get worse. With enough history, Intero can surface recurring observations and help you spot potential triggers. Intero uses a custom algorithm informed by clinical research on pelvic and bladder symptoms and conditions. It does not use AI or send any of your data to the cloud for processing. BRING A CLEARER HISTORY TO APPOINTMENTS Export a summary of your symptoms and patterns so you do not have to rebuild the story from memory in the exam room. PRIVATE BY DEFAULT No Intero account is required. Intero does not store your symptom or Apple Health data on its servers. iCloud backup keeps your encrypted data in your own iCloud account. Apple Health access is optional. PATIENT-FOUNDED, RESEARCH-INFORMED Built by a patient, Intero is designed for the messy reality of symptoms that flare, shift, and return. It draws on published research about pelvic, bladder, and urinary symptoms. Intero is a subscription app. A paid subscription is required to access the features described. Intero is not a medical device and does not provide medical advice, diagnosis, or treatment. It is for personal symptom tracking, pattern observation, and informational use.
