Helio Black&White Film Camera

Helio is a black & white camera app built for photographers who love the look and feel of real film. FIVE FILM-INSPIRED STYLES Choose from five distinct B&W looks — Pure for classic monochrome, Hard Contrast for punchy zone-adaptive tones, Reportage 400 for a documentary feel, Nocturne 3200 for high-speed pushed grain, and Chroma 400 for smooth chromogenic mono. Each style is driven by an on-device neural model trained to reproduce the tonal signature of its namesake. REAL FILM GRAIN, NOT FILTERS Helio uses on-device machine learning to generate authentic film grain — not overlaid textures or simple noise. Pick a grain preset (Fine, Medium, Heavy) or switch to Custom mode to fine-tune size, contrast, and per-zone tonal response (shadows, midtones, highlights) until the look is exactly yours. UNIFIED STYLE PICKER Style and grain controls live in a single sheet with visual previews of every option, so you can compare looks at a glance and dial in your shot in seconds — without leaving the viewfinder behind. WHAT YOU SEE IS WHAT YOU GET Every style, grain texture, and adjustment is rendered live in the viewfinder. The photo you capture is exactly what you see on screen — no surprises, no post-processing tricks. HIGH-RESOLUTION CAPTURE Shoot at up to 48MP with optional Apple ProRAW support. Helio takes full advantage of your iPhone's camera hardware. PRIVACY FIRST No accounts. No cloud uploads. No analytics. All ML processing happens entirely on your device. Your photos stay yours. Requires iPhone 13 or later for optimal performance.
