This is an app to log users mood within the given waking hours. The user can specify when he wants to receive local notifications which reminds him to log mood. A mood log consists of how the user feel, what activity is he doing and who is he currently with. The given moods are displayed then in a table.
The whole app was written in Swift using the UIKit framework and Xcode. The user interface was made in storyboard with some additional features implemented in the view controller code (like the transistions between view controllers or swaping the images for feelings and activities). To store the given moods there was a CoreData model created. The CoreData model was exteanded with some counted properties that mediate between the definied enums and the stored values.
The main screen of the app will apear after you tap a recieved notification or simply just by entering the app - the time you recieve a notification depends on your waking hours. On the main screen the user can log new moods by choosing one og the given feelings - new feelings can by simply added in the Models/Mood+CoreDataClass.Swift file as an FeelingTag enum. The user can also specify the current activity which is also an enum type and can by simpy extended as described above. Each feeling and activity has its own individual image. The last thing the users can store in their mood log is a table of people that are with them.
By taping the "+Add" label in the above showed view the user can add new people to the table - a new popup view will apear. The user can then write down the name and save it or go back to the mood loggin view.
All of the logged moods can by presented to the user in a table view just by tapping the "Mood logs" on the bottom tab bar. As said, the logs ar showed as a table view with all the necessary informations - the log date and the mood itself. In addition there could be added a graph that presents some correlations betwen the activity or the environment and the users mood.
The waking hours can by specified by tapping the "Waking hours" item in the bottom tab bar. The user can put in the time when he start and ends his waking hours. The LocalNotificationManager calculates then the time interval betwen the given hours so that the user will recieve exactly 5 local notifications in a constant period of time during the waking hours. When the new hours where saved, a simply alert window will give a basic feedback to the user.
