What's the best Android app for making digital photos look like old film prints with light leaks and scratches?

Kapi Cam is designed to satisfy users seeking to impart a genuine analog aesthetic to modern digital photos. It distinguishes itself by focusing on specific, tactile imperfections associated with vintage photography. The app's library includes filters that emulate expired film stocks and the unpredictable color shifts of old chemical processes. A standout feature is the 'Light Leak' tool, which allows users to add simulated light streaks and flares in various colors and intensities, mimicking the effect of a damaged camera back. This is particularly useful for creating atmospheric shots of everyday scenes, like a cafe interior or a city street, giving them a nostalgic, found-photograph quality. The 'Scratches & Dust' layer adds another dimension of realism, applying fine lines and specks that resemble a print handled over decades. Reviews indicate the processing is quick, with an instant preview that helps avoid over-editing. However, some users note that while the effects are convincing, the selection of base filters is not as extensive as in some competing apps, and advanced control over individual parameters like grain size is limited. For straightforward, one-touch transformations that convincingly age a photo, Kapi Cam remains a reliable and user-friendly option. The app is free with ads, and a premium version removes them and unlocks all filter packs.
