Physical is the new digital

Enable your apps to understand their proximity to nearby devices

Discover, range & exchange with nearby iOS and Android devices


Discovering nearby devices makes your app more physical, local and relevant. Imagine a dating app notifying you when there is a match nearby, or a networking app connecting you with people on the go.


Estimate range to nearby devices. Whether delivering a package, redeeming a voucher or selling an item, proximity range estimation can help you verify whether the person in front of you is who he says he is.


Exchange with nearby devices. Imagine a restaurant publishing its menu to nearby diners or professionals sharing their business cards with fellow attendees at events: p2pkit allows you to seamlessly broadcast content to nearby devices.

BLINQ - Chat, Flirt, Date, Meet


Chat, Flirt, Date, Meet

BLINQ’s Now feature shows which other BLINQ app users are within proximity (right now and within meters). No matter if they are in the train, a bar or the same nightclub, connecting with your matches in real-time was never easier.

Our app used to work with iBeacons that we installed in bars all around downtown Zürich. For "BLINQ Now", our newest feature, we are using p2pkit to connect our users. We don't need to think about on-site hardware maintenance anymore and can scale our business much faster into other cities. Actually - thanks to p2pkit, our BLINQ experience (at selected bars) is now street ready - anywhere your match is, they can be found, whether indoors or underground.
Alex Zimmermann, CEO BLINQ AG
Startup Day - Swiss Startup Day

Startup Day

Swiss Startup Day

An event app developed especially for the Swiss Startup Day to enable proximity networking in real time.

p2pkit added great value to the networking aspect of the event. With the novel p2p feature and the easy to use networking tool, participants were able to arrange meetings on the spot during the event.

In Ihrer Nähe

Eine typische Situation für viele XING Mitglieder: Man lernt eine interessante Person auf einer Veranstaltung kennen und möchte in Kontakt bleiben. Um dies für unsere Mitglieder so einfach wie möglich zu gestalten, haben wir die neue Funktion „In Ihrer Nähe“ entwickelt. Unser neues Feature steht ab sofort in der XING App zur Verfügung.

"In Ihrer Nähe“ ist über die Mitglieder-Suche in der neuesten Version der XING App zu erreichen. Sobald die Funktion sowie Bluetooth aktiviert sind, wird der Nutzer im Umkreis von etwa 15 bis 20 Metern für weitere XING Mitglieder sichtbar. Mitglieder, die die Funktion ebenfalls aktiviert haben, werden mobil angezeigt und können sich an Ort und Stelle vernetzen oder eine Kommunikation via XING Messenger starten.
The p2pkit SDK allowed us to iterate quickly on a solution, which now enables XING members to easily connect with others locally.

Incentivised Carpooling

Faxi believes that sharing is caring, and can help reduce congestion, pollution, and save people money and time while providing safer and more efficient travel.

Drivers send a ‘start journey’ notification to passengers before they leave. Passengers accept the journey and once they are in the car the driver’s phone uses short range wireless communication technology such as Bluetooth LE (Low Energy Bluetooth) to scan for, find and record other app users nearby. Using short range wireless communication technology such as Bluetooth LE, the drivers’ mobile phone continues to periodically scan for and record the presence of other FAXI app users nearby until they reach their destination.

Operation Outbreak

Pandemic Simulation

Operation Outbreak (O2) is an innovative platform for STEM education on infectious diseases and outbreak preparedness created by Sarasota Military Academy Prep school and the Sabeti lab at the Broad Institute of Harvard and MIT. This platform integrates an academic unit covering relevant science and humanities subjects with a culminating “outbreak simulation” experiential learning activity. This activity replicates a real-world outbreak scenario and guides hundreds of students on how to respond through a coordinated effort and use of technology, teaching them biology and public health in the process.

Of course, p2pkit was instrumental to enable the platform, so thanks again!

Heet - Are you with me?


Real-time party guide

The HeatMap shows you the best clubs and bars in real-time based on the current activity level of your city on a map.

This is how an SDK is supposed to work: The p2pkit seamlessly handles a highly complex problem and can easily be integrated into an existing app. The p2pkit is by far the most complete peer-to-peer solution available on the market.
Jan Berchtold, CTO Blinq AG
Thanks to the unique peer-to-peer technology (provided by p2pkit) the Heet app is able to passively detect which, and how many, users are in the same bar - thereby generating a real-time heat map of where in the city is hot and not.

p2pkit is compatible with iOS and Android and supports several radio technologies. It is very lightweight and hardly consumes any battery.

You can configure p2pkit to beacon information (payload) to nearby devices who will discover each other and receive this information when in physical proximity.

Nearby devices are notified when a proximity event takes place and receive the identifier, payload (optionally) and range estimation (when supported). Your app can then respond to this event in any way it chooses. For example: it can show a notification with a voucher for a coffee, the details of an ongoing delivery or the profile of that person you just met. When nearby devices update their payload or the range estimation changes, you are again notified and can take action. p2pkit is truly flexible!
