Lock it now. Open it when you've made it. Senior year moves fast: the last dorm hangout, the final home game, the summer before everyone scatters. A graduation time capsule holds all of it until you're ready to look back.

A graduation time capsule is a shared album that a whole friend group fills during their final year, sealed until a date after everyone has scattered. Each person adds from their own phone, nobody can look early, and it opens for the entire group at the same moment. That's usually a year or five years out, when the group has stopped being in one place.
It solves a specific problem: senior year is heavily photographed and almost none of it is ever revisited. The photos live on twelve different phones, get deleted in storage cleanups, and are effectively gone within two years. A capsule pulls them into one album before that happens.
Not just the highlight reel: the whole friend group's version of senior year, freshman year, or the four years in between. Everyone contributes their own photos and videos, and nobody sees anything until the group decides it's time.
Not on graduation day. The best material is the ordinary weeks: the library at 2am, the walk everyone did daily. That’s over by the time you’re in a cap and gown.
A capsule can hold up to fifty people, so it scales from a house to an entire class. Each person contributes from their own phone and nobody sees anyone else’s additions.
Set it to unlock on a date, or only once everybody has physically checked in together, which turns the first time the group reassembles into the reveal itself.
The instinct is to fill it with graduation day. Graduation day is the most photographed and least interesting part of the year. Everyone already has those pictures.
A capsule filled with these is worth far more at a reunion than another set of cap-and-gown photos, which everyone’s parents already have.
One year out is the sweet spot for a first capsule. It's long enough that everyone's life has visibly changed, and short enough that the group is still in touch by default rather than by effort.
Five years out is the version people describe as worth the wait, and the one that most often gets abandoned. Five years is long enough for the group chat to go quiet and for nobody to remember the capsule exists. It works far better with a notification-based app than a shoebox.
At the first reunion, whenever that turns out to be, is the strongest option if the group already reunites. Rather than guessing a date, set the capsule to unlock only once every member has checked in within about a hundred metres of each other. It stays sealed for however long that takes, then opens in the room, with everyone there.
Up to ten members on a free capsule and fifty on a Pro one, which covers everything from a house to a whole graduating cohort. Everyone contributes from their own phone.
The capsule still opens on schedule for everyone else. Setting an upload deadline a few weeks before the unlock date, rather than the day before, collects noticeably more: most people contribute when reminded, not when invited.
Yes, up until whatever upload deadline you set. Plenty of groups leave contributions open through the summer, which catches the move-out and the scattering, often the most affecting part of the album.
It’s better at surviving. A buried box depends on somebody remembering the location and still living near it in five years. The trade-off is real, though: a physical capsule holds objects, and a digital one only holds pictures of them.
Illustrative: based on how people use Capsule during testing, not a verified review. Capsule is in private beta.
"We each remembered totally different things from the same trip. Seeing everyone's version at once felt like experiencing it three more times. Do it."
Seal a moment today. Open it together when it matters most.
