Spiralens

Spiralens is an Android camera app that helps users compose better photos by guiding them to position the subject according to the golden ratio and other composition rules. Tap your subject, follow on-screen arrows, and shoot when alignment is optimal. The app includes guides like golden spiral, phi grid, rule of thirds, symmetry and horizon level, and provides editing features such as golden ratio cropping, background blur, and color styles. It works offline and keeps all processing and photos on your device for privacy.
