Cloud Filter
Read full descriptionHide full description
Cloud Filter is where technical precision meets artistic melancholy. Inspired by the atmospheric soundscapes of Zaha Zagic, this app is a dual-purpose studio designed for those who value both aesthetic expression and digital solitude. ### Artistic Vision Give your photos a nostalgic, "artistically oblivious" aesthetic that mirrors the depth of memory. Apply curated filter collections that mirror the "Programmer Romance" themes of the Cloud Chaser, Idolatry & Free Will, Temp Sins, and Unspoken music projects. From dreamy, low-exposure looks to retro textures, Cloud Filter gives your images a cinematic, melancholy depth before they are tucked away. ### The Art of Hiding Beyond the surface, Cloud Filter features a sophisticated Secret Mode. Utilizing on-device steganography and encryption, you can embed private text or entire images inside a "cover" PNG file. Share hidden messages with friends through the art of the cover image, keeping your data invisible to the naked eye. ### Key Features: Cinematic Presets: Artist-curated filters including Dreamy, Retro, and Melancholy styles. Live Comparison: Seamless before/after toggles to refine your visual narrative. Steganographic Hiding: Switch to Secret Mode to hide data within the pixels of your photos. Dual Encryption Modes: Choose "Easy Mode" for quick access or "Precise Mode" for high-capacity secure hiding. Local-First Privacy: All processing, filtering, and encryption happen strictly on-device. No accounts, no cloud, no tracking.
Puro

It provides extensive manual controls for ISO, shutter speed, white balance, and exposure, along with live metering and composition tools.

- Standard mode with Apple's computational pipeline
- DSLR-style manual controls (ISO, shutter, WB, EV)

- Grid overlays and aspect ratio control

Verdict
The clearest difference is in-app purchases: Cloud Filter at none against Puro's 3. Cloud Filter also leads on iOS requirement (16.0 vs 18.0). On price, ads and device support there is nothing between them.
