If you're looking for a reliable and easy-to-use app for tracking your allergies, then My Pollen Forecast is an excellent choice. Developed by JRustonApps B.V., this free app is available for iPhone and iPad and falls under the Lifestyle category with a subcategory of Health & Fitness.

One of the most notable features of My Pollen Forecast is the ability to view hayfever forecasts for the next 2 days on a map showing areas with the highest pollen count. The app also provides a 2-day pollen forecast with temperature, wind, and humidity information. You can use the app to track your symptoms and monitor them over time. Plus, by adding diary entries frequently, you can discover which pollens you are most allergic to.

With push notifications, you'll be alerted when the pollen count is expected to be high. The app also supports the latest iPhone and iPad models. However, it's important to note that the app currently only supports the contiguous US and the UK, and not states like Alaska and Hawaii.
