Notific doesn’t impact battery life as it will only use the proximity sensor for 10 secs.
The memory usage is highly optimized (2-10MB) and doesn’t use 50MB+ as in other notification apps.
You can unlock directly by double tap on circular drag handle.
Drag and hold on the dismiss spot to dismiss all notifications
Proximity sensor values are calibrated for Nexus devices by default. If you have problems with the sensor on
Galaxy or Xperia devices, try calibrating the sensor from Troubleshooting settings or Turn Off Pocket Mode.
