Put seventy thousand people in one stadium and something quietly fails: the network. Everyone reaches for a phone at once — to send a photo, check a score, pull up a ticket — and the towers, built for an ordinary crowd, buckle under the surge. In that moment you learn something about every app on your phone: the ones that keep working, and the ones that don’t.
Most software today is built on a quiet assumption: that the connection is always there. It assumes the server is one quick request away, that your data lives in the cloud and can be fetched on demand, that “offline” is a rare error state rather than a normal condition of life. For most of an ordinary day, in an ordinary place, the assumption holds. And then you walk into a crowd, a tunnel, an elevator, or a part of the world the map forgot, and it doesn’t.
When it fails, the difference between apps becomes stark. The ones that kept your information on the device keep working — your notes, your tickets, your photos, your records are simply there, signal or no signal. The ones that treated your phone as a window onto a server go blank, or spin, or quietly lose what you were doing. The same data, the same phone; only the assumption was different.
This is the practical case for what’s sometimes called local-first software — tools that keep your information on your own device and treat the network as a convenience, not a lifeline. It isn’t mainly an argument about privacy, though it touches that. It’s an argument about whether the thing in your hand actually works when you need it — including in the exact moments, a packed event, a dead zone, a long journey, when you most often do.
There’s a tendency to treat connectivity as solved, as if signal were now ambient and total, like air. It isn’t, and it never quite will be. Networks are finite, crowds are real, and the edges of coverage are part of ordinary life rather than an exception to be designed around later.
Software that only works under perfect conditions isn’t finished software. The honest test isn’t whether a tool works at a desk on good Wi-Fi. It’s whether it still works when the connection is gone and the crowd is roaring — whether what’s yours stays usable when the network gives out.
That’s a line we build on the right side of — your information kept on your device, working with or without a signal. See what we’re building →
