Shipping About Nightshade: Focus All apps
Releases
| Version | Date | Notes |
|---|---|---|
| 1.0 | Not yet released | First release. Detection, timer, alerts and trial. |
Known issues
- Dark sunglasses defeat detection. Heavily tinted or polarised lenses block both infrared and visible-light paths. The app drops to head-position tracking and tells you it has.
- Detection pauses during a phone call. iOS gives the camera to the call. The session pauses, the notification says so, and it resumes when you return.
- Low-light sensitivity. In dim rooms, detection relies on the visible-light camera and may reduce precision. Best results with some ambient light.
Requirements
| Platform | Minimum | Note |
|---|---|---|
| iPhone | iOS 16.1 | Face ID models track in complete darkness using the infrared camera. Older models use the normal camera and need some light. |
