Modern smartphones carry a rich, physics-based sensor suite - accelerometers, gyroscopes, device motion and ambient signals. These sensors describe the physical relationship between a human and their device in 3D space. Until now, this information has been difficult to access, interpret and apply in a consistent way for product and growth teams.
The Layer That Unlocks Real-World Intelligence
ContextSDK is building the essential data infrastructure layer that collects, normalizes and makes on-device contextual signals available for the entire ecosystem.
Sensor Abstraction: We handle the complex physics engines, motion modeling and cross-device normalization so you don't have to.
Privacy-First: All processing happens on-device. No identity tracking, no cross-app fingerprinting - just physics-based truths.
Real-Time Decisions: Millisecond-level SDK performance for instant decisions at the moment of user interaction.
Clean Integration: A stable, standardized API layer that plugs into any part of your data pipeline.

What industry-leaders say
"ContextSDK and its assessment of real-world context adds a unique new data vector to close the loop on conversion to achieve 360 degree contextualization. This will advance the mental models of measurement across the mobile ecosystem."
"ContextSDK creates value for mobile app product owners from day 1, shedding light on insights such as the impact of real-world context on session length."
"With ContextSDK we address a crucial blindspot in our Analytics Setup: the real-world context of a user when using our app. For the first time we will have a 360 degree contextualized picture how our customers are using our app"
"Our ContextSDK partnership enables us to have a compelling AI narrative when speaking with prospects. Many other approaches to AI in our market have limited value. But ContextSDK can actually drive meaningful impact on engagement and conversion rates."
"For me this is a no-Brainer! As a product owner I'd love to learn more about the real-world contexts in which my users are using my apps - this will allow me to design better customer journeys."
