Read the full description
Spiralens is an Android camera for people who never learned composition. Tap your subject, follow the arrow, and shoot when the ring turns green: the subject sits on the golden point and the phone is level. Guides for golden spiral, phi grid, rule of thirds, symmetry and horizon. The editor adds a golden-ratio crop, straighten, drag-to-crop and a new background blur that keeps your target sharp. Works offline; photos never leave your phone.

Partial While camera overlays and sensor listeners are easy, reliable real-time visual subject tracking fused with device orientation on Android requires non-trivial computer vision optimization.
What it would actually take: A production version requires an Android stack using CameraX/Camera2, OpenCV or MediaPipe for real-time visual tracking (e.g., optical flow or correlation filters), and SensorManager for inertial sensor fusion. The primary challenge is maintaining low-latency, frame-accurate tracking of arbitrary user-tapped subjects without thermal throttling across fragmented Android hardware. This requires mobile computer vision and low-level performance profiling expertise.
