A Timeline project is what you start with when you open 1SE. It's the "OG" 1SE calendar. The Timeline project allows you to select one second every day on your calendar. This second can be from a photo or video.
Don't forget, you can [make multiple Timeline projects]. Some folks have one for each family member, pets, school, or exercise. Whatever works for you.
What's with the teal days?
You can tell if you have a video or photo on a calendar day because it appears teal. Tap on any of these days to see the content available to grab a second from.
TIP: You can also grab a video or photo from ANY day on your phone, then use it on a calendar day in 1SE. Just tap on the day and search your library.
Tap on the name of your project to open your project list. This is where you can [delete projects, rename them], or [make new ones]. When you delete a project, all the seconds are also deleted and this isn't undoable. BE CAREFUL!
Finally, there's also Freestyle projects, which are great for trips, weddings, and DIY projects. To learn more about how to use Freestyle projects [please go here].
TIP: Your calendar automatically expands as you use 1SE. Growing with each new day.
