Tags are a lot like categories – they are added to your journals to help you sort and organise your entries later. For example, if a certain entry is related to say a birthday event, you can tag the entry with the tag ‘Birthday’ (apostrophes are not required in the app). So later on when you want to view all entries relating to any birthday event, it makes it easier for you to just view entries by the ‘Birthday’ tag, which will quickly bring up all the relevant tags that you have specified for the journal entry.
