In Arabic, Hisn translates to fortress. Hisn Labs was founded to help maintain your focus during daily prayer. We aim to build quiet, privacy-first tools that solve real problems without demanding your attention—ensuring your phone serves your prayer, rather than distracting from it.
Sujood Sense
Touchless Rakat Tracking
Designed to safeguard Khushu. By silently offloading the cognitive load of counting Rakats, Sujood Sense eliminates the anxiety of forgetfulness and protects your prayer from the whispers of doubt.
The Architecture
Proximity Counting
Utilizing the device's infrared hardware to intelligently detect movement during Sujood, accurately tracking your Rakats without requiring physical touch.
Zero-UI Logic
Designed on the principle that the best interface is unseen. Our haptic feedback system is calibrated to guide you physically, without demanding visual attention.
Edge Processing
All sensor logic and prayer data are processed locally on your device. We believe in total data isolation—no clouds, no telemetry.
Khushu Preservation
Operating with a true black OLED interface, the screen's pixels physically turn off. The app stays awake to track your movements while emitting zero light, removing all visual distractions.
Direct Installation
Download v1.0.0 APKWhy isn't this on the Play Store?
Mainstream app stores mandate the inclusion of underlying SDKs that track usage, collect analytics, and build behavioral profiles. We believe a prayer app should not double as a data harvester. By providing the APK directly, we guarantee Sujood Sense remains a closed, isolated system with zero third-party telemetry.
