The mood screen after logging moods prompts the user to add symptoms, but if you don't wish to add a symptom it isn't clear how to exit the flow. There is a back button, and it does say the mood was logged, but having the mood faces remain up makes the user second guess if they must add a symptom to have the mood recorded. Maybe there should be a splash screen in between which shows the recorded mood and prompts the user to add notes or check in with their body to record symptoms.
