On-device context for mobile intelligence
The essential data infrastructure layer that unlocks real-world device signals for smarter decisions, better timing and privacy-first operations.
A new category of data is emerging
Every major shift in the data ecosystem has been driven by a new, previously inaccessible signal. The next frontier is directly on your users' phones.
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.
Privacy-First:
All processing happens on-device. No identity tracking, no cross-app fingerprinting - just physics-based truths.
Sensor Abstraction:
We handle the complex physics engines, motion modeling and cross-device normalization so you don't have to.
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.

Wondering how context-aware data can improve your app?
Every app is different. We sit together in a hands-on session to explore your product, your users and your flows - then uncover the moments where context can drive the most impact. From real-world signals to actionable insights, we’ll help you turn data into decisions.
What industry leaders say
"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."
"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."
"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."
"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."

FAQ
How quickly can ContextSDK be integrated?
Most integrations are live within a day. Just a few lines of code, no new app permissions required.
Which mobile platforms does ContextSDK support?
iOS. Android support is on the roadmap.
How is ContextSDK different from analytics tools?
Analytics tools report on what users have done. ContextSDK detects what users are doing right now - their physical context in the real world - so apps can act in the moment, not after the fact.
Does ContextSDK collect personal data?
No. All processing happens on-device. No PII is ever collected, stored or transmitted. ContextSDK is GDPR compliant and SOC 2 Type 2 certified.
What signals does ContextSDK use?
Accelerometer, gyroscope, device activity, screen state, ambient signals and motion patterns - over 300 signals in total, all processed locally on the device.
What is ContextSDK?
ContextSDK is an on-device context intelligence platform for mobile apps. It processes real-world device signals - motion, activity, device state - through on-device ML models to help apps act on what users are actually doing, not just who they are.
