This is a great way to organize your photos. You can save photos you have of your friends in a birthday event. Here you can see how many days there is to the birthday and how old he or she will be. In your birthday event you can add as many pictures as you like. To share them, tap and hold on the picture. You can then choose how many pictures you want to share or delete.
It is also a great way to organise your events. This could be a vacation you are looking forward to. Set the date to when you are leaving and Hodie will count down the days till you leave. On your vacation, save the photos you are taking to the event you created. You can then use the event to look back at all your great photos and memories from the vacation. A year later, on the same date you left on your vacation, Hodie will bring up your event on the top of your feed, so you can look at what you did on that day of the year.
