About Double Stop

Why Double Stop?
Double Stop is a social signal for the physical world. It fills a gap that every app has ignored: the space between being alone in public and being genuinely open to a conversation.
Whether you are sitting alone at a café, relaxing in a park, browsing an art gallery, waiting at a transit hub, or before or while shopping at the supermarket — you are already there. Double Stop lets you signal to the people around you that a friendly hello is welcome, without interrupting your day or giving up your privacy.
Transparency and safety are built into the design at every step. Your detailed location and appearance remain hidden until someone nearby actively chooses to engage. Every post carries a shared social protocol: if someone approaches you with ‘D-Stop, [your name]?’, both of you know precisely what is happening — a mutual, informed decision to say hello. Posts expire automatically after one hour and nothing persists. The system is designed from the ground up so that spontaneous connections happen on your terms.
How It Works, Step by Step
Step 1 — Post a Signal.
You find yourself with unexpected idle time or a sudden desire to connect, no matter where you are or what time it is. Instead of losing that moment to a smartphone screen, you drop a local 1-hour social signal from your exact location.
Step 2 — Stay Private by Default.
Specify your current situational context and preferred activity. Let nearby people know your timeline — whether you have just 10 minutes to spare or longer — and what you are open to discussing or sharing in that exact moment.
Step 3 — A Stranger Says Hello.
Nearby people in your immediate vicinity see your active signal. Because the platform provides a verified, safe space to meet a stranger platonically, they can confidently choose to unlock your specific location details to coordinate a quick hello.
Step 4 — The Post Expires.
A completely friction-free, spontaneous connection happens right where you are. You spend your brief window exchanging ideas, sharing perspectives, or enjoying a quick real-world conversation with someone you otherwise never would have crossed paths with.
Practical Scenarios: When to Use Double Stop
The Remote Professional & Café Culture
Imagine you are working remotely from a café in any city. You are open to a brief networking conversation or a professional coffee break, but interrupting strangers with headphones on is socially awkward. By dropping a 1-hour Double Stop pin indicating your table location, industry, and availability, you create a seamless, friction-free opening for fellow remote workers in the immediate vicinity to say hello.
The Solo Traveler & Cultural Exploration
When exploring a new city alone — such as wandering through a local museum or navigating a busy transit hub — finding spontaneous company can be challenging. Dropping a local signal flare lets other solo travelers or welcoming locals know you are open to sharing a casual lunch or navigating a cultural landmark together, operating entirely on a safe, platonic framework.
Who is Ina Works?
Ina Works is an independent software studio founded in 2025 and based in Salzburg, Austria. Every design decision is made by a single developer, guided by Austrian law and European data protection standards. The studio has no investors, no growth targets, and no advertising partnerships that conflict with user privacy. The product is accountable to its users and to Austrian courts — and that is intentional.
Privacy by Design
Double Stop has no mandatory user accounts and no photo uploads. This is not a limitation — it is an architectural decision made to protect you from the moment you open the app.
Your identity on Double Stop is three things: a name you choose, a brief description of your appearance, and a pin you place on a map. Posts expire after one hour. A private archive is retained for 90 days solely for legal compliance under Austrian law, then permanently deleted. There is no profile page, no post history visible to others, and no data sold to third parties.
Where It Started. Where It Goes.
Double Stop did not emerge from a product sprint in a corporate office. It grew from a personal observation: that in any city, people share the same tables, the same parks, the same waiting rooms — and yet remain strangers. Not because they are unfriendly, but because there is no signal.
That observation shaped the design instincts behind the product. The 1-hour post limit reflects knowing that a café table is not a permanent reservation. The decision to use descriptive location hints rather than raw GPS coordinates reflects knowing that "the bench near the fountain" means more to a human than decimal numbers. Privacy by default reflects the understanding that a genuine connection should never require surrendering your identity in advance.
Those principles apply everywhere people share public space — in Tokyo, Buenos Aires, Nairobi, Berlin, Seoul, and every smaller city in between. Double Stop is designed to work wherever there are cafés, parks, transit hubs, bookstores, and people who would make a good conversation if only there were a bridge. The world is where it belongs.
