One second a day becomes your universe.
StarryDays is a video diary built on a single rule: keep just one second of every day. Hold to capture a second, or slice one from your camera roll. Day by day, your days grow into planets; year by year, your years grow into galaxies. When a year completes, you own a universe made entirely of your own life.
ONE SECOND IS ENOUGH
- Hold to record — it ends on its own at exactly one second
- Or pick a video from your library and carve out its best second
- One second per day keeps journaling light enough to actually stick
DAYS GROW INTO PLANETS
- Record each day of the week and your planet grows a little more
- A full week of moments brings a planet to its complete form
- Every week births a planet; every year grows a galaxy
RECOVER YOUR PAST FROM THE CAMERA ROLL
- On first launch, StarryDays finds one second in every day you've already filmed — and returns it to that exact day
- Days you forgot about arrive in your universe one by one
- Missed a day this month? Fill it in anytime
RELIVE YOUR UNIVERSE
- Rewind cuts your week, month, or year into a film, ready to export and share
- Wander your universe year by year: planets, galaxies, and the still-condensing nucleus at the center
- The Celestial Codex collects every kind of planet you've grown
PRIVATE BY DESIGN
- iCloud sync keeps your universe safe across devices
- No account, no social feed — your universe belongs to you alone
- Capture from Control Center, Lock Screen, or the Action Button, so you never miss a second
