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.

Observer
Read full descriptionHide full description
A self-reflection tool for hard weeks. You write about a recent period work, family, what's been on your mind, what hasn't. Don't clean it up. The point is to let it come out the way it actually does, not the way you'd report it to someone. Observer reads what you wrote and returns observations flat, factual, no reassurance. Calibrated for the things autistic and neurodivergent people often miss in themselves: where presentation has gotten more polished under load (a stress signal, not a wellness signal), what's carrying disproportionate cognitive weight, what's conspicuously not in the account at all. It's not a diagnostic tool, a therapy app, or a coach. It doesn't track moods, suggest interventions, or store anything on a server. It's a writing tool that surfaces patterns in your own words for you to interpret. It was built after a hard week. A sick dog needing emergency surgery, family worry, a hard week at work. When reflecting clearly on what was actually loading me up was harder than it should have been. The first thing the app surfaced was something I hadn't connected: a complicated piece of work running quietly in the background was contributing more than I'd given it credit for.

Verdict
