1SE, also known as 1 Second Everyday, is a mobile application designed to help users document their lives by capturing a single second of video each day. The app then compiles these snippets into a chronological movie, allowing users to relive their memories in a concise format. The concept was created by Cesar Kuriyama, who originally started the project as a personal mission to record his life when he turned 30. After a TED talk he gave on the subject went viral, he launched a highly successful Kickstarter campaign in 2012 to develop the app for the public.

While the product is digital software, its development and headquarters are rooted in the United States. The company operates as an independent private entity, 1 Second Everyday Inc., which continues to manage the app's features, including the 'Freestyle' mode and collaborative tools. The app gained significant cultural recognition when it was featured in the 2014 film 'Chef', which showcased the application's ability to tell a visual story over time.
