Apple is reportedly working on a health-led journaling app for the iPhone, codenamed “Jurassic”. The app would be able to track a user’s daily routines, activities, and people they interact with. It would also offer personalization features and suggest relevant journaling topics.

Data collected by the app would be stored solely on-device and journaling suggestions would be automatically deleted after four weeks. The app, once released, could be in direct competition with Day One. Apple has not officially announced anything about the app and is likely to do so by June.
