Read full description

Find your unique pain patterns through barometric pressure changes and headache logs. This app is a dedicated application combining weather forecasts and physical condition tracking, developed for those suffering from headaches (weather pains, meteoropathy, migraines) caused by barometric pressure fluctuations. It supports you in taking countermeasures before the pain worsens by grasping in advance the timing of significant pressure drops. ## Main Features ・High-Precision Barometric Pressure Forecast Graph Equipped with an intuitive graph that allows you to check future barometric pressure changes at a glance. It visually highlights and notifies you of the pressure warning zones (such as sudden pressure drops) where headaches are likely to occur. ・Barometric Pressure Drop Alert (Push Notifications) Before the barometric pressure changes suddenly, it will notify you with a push notification on your smartphone. It makes it easier to notice weather changes even when you are out, allowing you to take proactive measures such as preparing your medication before the pain occurs. ・Easy Headache and Medication Log When you feel pain, you can quickly log the pain intensity and the medication you took (timing of medication). We have adopted a simple design that reduces the burden of input so that you can continue to use it every day. ・Pain Analysis and Review You can cross-reference past weather and barometric pressure data with your headache logs. Understand the conditions and trends under which your pain is likely to occur, and use it to improve your lifestyle habits. ・User-Friendly Customization Flexible customization according to the user's preference is possible, such as switching to an eye-friendly dark mode and changing the barometric pressure units (hPa, inHg, etc.) and temperature units. ## Recommended for These People Those Who Get Headaches or Feel Sluggish on Rainy Days or When a Typhoon Approaches (Meteoropathy, Weather Pains) Those Who Want to Understand the Patterns and Triggers of Their Migraines Those Who Want a Guideline for When to Take Medication Those Who Want to Easily Log Daily Physical Condition Changes Instead of Using a Notebook Those Who Are Looking for a Stylish and Easy-to-Use Healthcare App ## Important Notes This app supports physical condition management based on the user's own records and weather forecast data, and is not a substitute for diagnosis, treatment, or prevention by a medical institution. If you have health concerns or pre-existing conditions, please be sure to consult a doctor or medical institution. --- Terms of Use https://www.knecht.co/guidelines/terms-of-service Privacy Policy https://www.knecht.co/guidelines/privacy-policy
