If you plan your day around bathrooms, brace before you sneeze, or skip the run because you might leak, you are not alone, and you are not out of options. Control is a discreet, private coach for your pelvic floor: a guided exercise timer, a fast bladder and leak diary, and a progress tracker built for real life. WHAT YOU GET - A short self-assessment that maps your answers to a leak pattern and a Self-reported Control Score, so you can see where you're starting from - A 12-week guided plan of slow holds and quick squeezes, built around your answers and progressed gradually week by week - Guided sessions that take just minutes, with a calm visual pacer, haptic cues, and a discreet mode with neutral lock-screen wording - "The Knack": a practiced brace-before-you-sneeze timing skill you can learn in one sitting - A fast 3-tap diary for drinks, bathroom visits, and leaks, plus a Trigger Map that shows your most common triggers and times of day - Gentle, fully customizable reminders that never mention leaks on your lock screen - Progress views for consistency, leak trends, and confidence, plus a clean PDF report you can hand to your doctor or pelvic-health physio HOW IT WORKS Answer a few questions (about 90 seconds). See your pattern and score. Try one full guided session free. Then follow your plan: short sessions, three times a day, with reminders that fit your routine. Everything stays on your device: no account, no cloud, your health answers are never transmitted. A NOTE ON SAFETY Seek a doctor's advice in addition to using this app and before making any medical decisions, including starting or changing an exercise program. Control is a self-management and adherence aid, not a medical device. It does not diagnose any condition, measure or detect muscle contractions, or guarantee results. Clinical guidance recommends supervised pelvic floor training for incontinence; Control helps you stay consistent and encourages professional assessment when your answers suggest it. If you have pain, blood in your urine, or sudden new symptoms, seek medical care. SUBSCRIPTION Control Pro unlocks the full 12-week plan, unlimited sessions, custom reminders, diary insights, the Trigger Map, trends, and PDF reports. Subscription options: - Control Pro Monthly: $9.99 per month - Control Pro Annual: $39.99 per year, with a 7-day free trial Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the trial or current period, and your account is charged for renewal within 24 hours prior to the end of the current period. Manage or cancel anytime in your App Store account settings. Any unused portion of a free trial is forfeited when you purchase a subscription.
