Polca BW is a retro camera application designed for iPhone users. This easy and fun app offers a unique experience for photography enthusiasts. With 3 stage scene modes, users can capture various film-style photos.

By pressing the shutter for different durations, users can access different effects. The basic scene mode captures standard photos, while holding the shutter until the 1st stage lamp turns on creates photos with light leak effects. The 2nd stage lamp produces photos with a weak damage effect, and the 3rd stage lamp adds a strong damage effect resembling coffee stains.

Additionally, users can choose to include dates and borders in their photos by toggling the respective switches. Polca BW aims to bring the charm of simple film cameras to daily life.
