Field notes
The sample screens show logging mood, mind, body, energy, and activities, with diary notes presented as optional. Luna says users switching from another period app can upload calendar screenshots, review detected dates, and edit them before adding. Its partner-sharing controls are described as selective: the user chooses which categories appear, while diary notes remain private. The homepage lists a seven-day trial followed by monthly or annual pricing.
