EpiCentr app is designed for individuals with seizure disorders and their caregivers. It’s intended to enhance safety and support during seizure episodes by alerting emergency contacts. It also includes a comprehensive journal to track seizures and detailed statistics reports for doctors. The app actively monitors seizure-like triggers, promptly alerting your designated emergency contacts if a seizure is suspected. Specifically, our watch app utilizes Apple HealthKit to track user’s heart rate, while leveraging the gyroscope and accelerometer on Apple Watch to monitor the user's arm motion. If a seizure-like pattern is detected, an alert is promptly sent. For immediate assistance or in case if Apple Watch is not available, manual alerts can be initiated directly from your iPhone. Additionally, the app allows you to maintain a detailed journal, effortlessly tracking triggers and recording side-effects, auras, and personal notes. Keeping all data at one place, the app provides reports with important descriptive statistics giving valuable insights to you and your healthcare provider. KEY FEATURES AND HOW TO USE THE APP: - Seizure Detection: By utilizing your Apple Watch, the app monitors various seizure-like triggers, such as motion patterns associated with tonic-clonic seizures, different types of falls, and abnormal heart rate. If any of these triggers are detected, the app initiates a delayed alert, which will be automatically sent to your emergency contacts if not manually canceled within 30 seconds. Set up automatic seizure monitoring by following the instructions provided in the app. - Manual Alerts: Activate alerts instantly from your iPhone or Apple Watch. Choose between two alert types: Help Now, which sends an immediate notification, and Delayed Help, where a 30-second countdown is initiated before sending the alert if not canceled. - GPS Location Sharing: When a help request is sent, the app automatically includes your GPS coordinates (if available) in the notifications sent to your emergency contacts. This crucial information enables them to locate you swiftly, ensuring timely and accurate assistance. Please grant location sharing permission to the app for this feature to function. - Journal: Keep track of vital information about your seizures using the app's comprehensive journal. Effortlessly monitor triggers, record side-effects, track auras, and add personal notes. Seizure records are automatically captured, and you have the option to edit or add necessary details. Over time, the app consolidates all this essential data in one convenient location, providing you and your healthcare provider with detailed reports featuring important descriptive statistics. - Roles: The app operates in two modes: one for individuals with seizure disorders and another for their caregivers. Download the EpiCentr app now to experience a new level of confidence and security in managing seizures and seeking help when it matters most.

CVS Tracker helps parents and carers record Cyclical Vomiting Syndrome episodes with calm, organised logging, even in the middle of the night. ONE TAP TO LOG Tap Sick now and the time is recorded, starting an episode if one isn't running. Add more when you can: how severe, symptoms, sleep and notes. If you tap by mistake, Undo is right there. SICK NOW FROM ANYWHERE While an episode is running, the Lock Screen and Dynamic Island show when they were last sick and how many times so far, with a Sick now button that records the time without opening the app. You can also long-press the app icon, ask Siri, use Shortcuts or the Action button, or add a Control Center button. Names stay off the Lock Screen unless you switch them on. ONE TIMELINE PER EPISODE Everything logged in an episode appears in one timeline, with when they were last sick at the top. Tracking more than one person? The app asks who's sick and keeps an episode for each. MEDICINES, AS YOU ENTER THEM Medicines are recorded exactly as you type them, and ones you've recorded before can be entered again in a tap. Set an optional reminder at the interval you choose; it tells you what was given and when. PATTERNS Plain answers about what you've recorded: how often episodes happen, how long they last and when they start. DOCTOR REPORT A clear summary of one episode or a period, to share with your medical team. Share it as a PDF, or as a CSV for spreadsheets, with Premium. EASY ON TIRED EYES Light and dark appearances, with colours that dim and warm automatically at night. FAMILY SHARING (Premium) Each carer uses their own account. Whoever logs, both phones stay in step, and each entry shows who logged it. One Premium purchase covers your whole family and includes cloud backup. PRIVATE BY DESIGN Your records are stored on your iPhone and work offline; no account is needed unless you share or back up. App Lock can ask for Face ID or your passcode. No ads, no data selling, no unnecessary tracking. CVS Tracker records what you enter. It doesn't give medical advice, diagnose, or suggest medicines or doses. Always follow your medical team's guidance. The Lock Screen needs iOS 17 or later; the Control Center button needs iOS 18 or later.
