.App Usage and Engagement Analytics

[Jahangir307]

When users spend time on certain apps (shopping, fitness, travel), it’s a signal of short-term interest. SDKs embedded in thousands of apps quietly collect:

Time spent per screen

Clicks and swipes

Scroll velocity

App-switching behavior

If a user browses several travel blogs, opens Airbnb, then vietnam phone number list checks Google Maps, the system infers intent and serves timely travel deals.

C. Sensor Fusion and Environmental Context
Modern smartphones are packed with sensors: accelerometers, gyroscopes, microphones, ambient light sensors, even barometers. When layered together:

Walking + early evening + dark mode = commuter

High-speed movement + headphones in + GPS on highway = passenger

Phone tilted vertically for long durations + repeated screen taps = engaged reader or gamer

These signals allow brands to time their outreach—sending a promo during a moment of calm, not while someone is in motion or talking.
