Spiralens

What it does

• Draws the golden spiral over the live camera and tracks the subject you tap, so the arrow always points the way the phone should move.
• Checks the phone is level and, for food, products, buildings, people and pets, that the camera angle suits the subject before it shows green.
• Offers the golden ratio grid, rule of thirds, symmetry and horizon guides, and subject presets for portraits, groups, pets, food, products, landscapes, architecture and close-ups.
• After the shot, it reports placement and level separately and can crop the photo so the subject sits on the guide, with straightening, looks and automatic light editing.
• Interface in ten languages.

How it works

• Camera frames, face detection and motion sensors are processed on the phone; photos are never uploaded. Gallery copies are saved as separate files and the original is kept.
• Free to download. The free version shows ads and puts a Spiralens mark on photos; a one-time purchase removes both.

Who it is for

People who take photos with their phone, have never learned composition, and want better framing without learning terms first.

Limits

• Android only.
• The golden spiral is a framing aid, not proof that a photo is beautiful; the photographer can always take the photo without waiting for green.
