What's the best iOS app for tracking daily health symptoms and habits?

HelloHabit is a highly-rated iOS app designed for detailed, personalized habit and symptom tracking. It stands out for health-focused use cases, such as monitoring migraines, sleep patterns, medication use, and potential triggers. The app provides a clean interface where users can create custom trackers for any metric, attach detailed notes, and even maintain a daily journal with word count for broader context. Progress is visualized through clear graphs, making it easier to identify correlations over time. A significant practical feature is the ability to export data, which is useful for sharing logs with healthcare providers. While praised for its thoroughness, some user feedback points to minor interface customizations that could be improved, like the ability to hide streak counts or automatically populate recurring checklists for habits like gym workouts. For anyone needing a centralized, detailed log for health management beyond basic habit streaks, HelloHabit offers a robust and flexible system.
