Why I Built Snack Signal: The Ice Cream Truck That Never Came

It always starts the same way. Somewhere in the neighborhood — two blocks over, maybe three — the jingle.

If you have kids, you know what happens next. Everything stops. Homework stops. Dinner prep stops. The dog starts barking because the kids are yelling, and the kids are yelling because the ice cream truck is coming — which, to be clear, nobody actually knows. Nobody knows where it is. Nobody knows which way it’s headed. All we have is a faint song drifting over the rooftops, like a rumor.

And then the scramble. Do I have cash? I never have cash. Nobody has cash anymore — except the ice cream truck only takes cash, so now I’m going through coat pockets and the junk drawer and that mug on the counter that eats loose change, while my kids stand at the door vibrating like tuning forks.

We make it to the curb. And we wait.

Twenty minutes at the curb

Here’s the thing about sound: it travels. A jingle you can hear clearly might be six streets away, on a route that will never touch yours. But try explaining acoustics to a kid holding a fistful of quarters.

So we stood there. Ten minutes. Fifteen. Twenty. The jingle got louder, then quieter, then louder again — the truck was orbiting us like a satellite that never lands. And then it faded out entirely, somewhere in the direction of the next neighborhood over, and I walked back inside with two very quiet kids and the specific flavor of annoyance that comes from having donated twenty minutes of your evening to a truck that never knew you existed.

That last part is the whole problem, and it took me an embarrassingly long time to see it: the truck never knew we existed.

The night that made it non-negotiable

There was another evening — the one that turned this from a gripe into a project. The jingle hit, and before anyone could react, my younger kids were out the door. Alone. Gone, chasing a sound down the street, at an age where they should not be navigating the neighborhood solo on a sugar-fueled mission.

Everyone was fine. But standing on the porch doing the frantic-parent scan of the street, I remember thinking: this is a solved problem literally everywhere else. I know when my package is four stops away. I can watch a rideshare inch toward me on a map. But the ice cream truck — a vehicle whose entire business is being found by children — communicates its position exclusively by song, and my kids’ response is to launch themselves at it like it’s 1962.

I didn’t want my kids to stop loving the ice cream truck. I wanted the chase to be unnecessary — for the truck to come to us, at our driveway, with enough warning that going outside is a family stroll instead of a jailbreak.

Both sides of this are flying blind

Once I started pulling on the thread, the frustrating part is how mutual the problem is.

Think about it from the driver’s seat. That truck that orbited us for twenty minutes? It was full of ice cream, burning gas, driving past houses full of kids who wanted ice cream — and the driver had no way to know. They’re out there guessing: this street, this hour, this weather, maybe somebody comes out. We were standing at the curb with money, wanting exactly what they were selling, and the two sides had no way to find each other beyond a jingle and luck.

The residents can’t see the truck. The truck can’t see the demand. Everybody loses — the family at the curb, the driver watching margin melt, and every would-be vendor who looked at those economics and decided not to try.

That’s not a truck problem. That’s a signal problem.

So: Snack Signal

Snack Signal is the app I wanted on that curb. Here’s what it does today:

  • Follow your favorite trucks. When one you follow is near your neighborhood, you get an alert — not a rumor over the rooftops, an actual heads-up with time to put shoes on.
  • Raise the Snack Signal. One tap drops a request pin at your home. You’re not chasing the truck; you’re telling it come here — we’re in.
  • Watch it come to you. The truck moves on a live map with a real ETA, so “is it coming?” has an answer that isn’t twenty minutes of curbside hope.
  • Vendors see every raised hand. Drivers get a live map of pins, sorted by distance and ETA, and drive to confirmed demand instead of wandering.

That’s the shipped product: the treats come to you, and the truck stops driving blind. No more sprinting kids, no more satellite orbits, no more donating your evening to a jingle.

And the cash scramble? Not solved yet — I’ll be honest about what exists and what doesn’t, always. But an account you approve from your phone, no wallet needed even when you’re dripping wet at the pool, is exactly the kind of thing we’re building toward. The bigger picture — neighborhoods served by all kinds of trucks, on schedules you can count on — deserves its own post, and it’s coming.

Raise your hand

Snack Signal is free for residents, and it’s built for ice cream trucks first — with room for every kind of mobile vendor after that.

If you’ve ever stood at a curb listening to a jingle fade into the next neighborhood, this is for you. Follow a truck. And the next time you hear that song: don’t chase it. Raise your hand. The treats come to you. 🍦
