Halide’s update for iPhone Duo
Halide, the third-party camera app developed by Lux Optics, has released an update tailored for the iPhone Duo, Apple’s first foldable device. The update introduces features designed to optimize the app’s functionality across the device’s three distinct screen poses, which include fully closed, partially open (like a tent), and fully open modes.
New features for foldable poses
The update’s standout addition is a waist-level viewfinder mode, which activates when the iPhone Duo is used in its partly-open pose. This feature mimics the experience of traditional waist-level viewfinders found in medium-format cameras, allowing users to compose shots from a lower angle without raising the device to eye level. Other pose-specific adjustments were not detailed but are likely included in the update.
Availability and future developments
The update is available immediately for Halide Mark III users. Lux Optics has suggested that more Duo-focused features are in development, though the company did not provide specifics or a timeline. According to Engadget, Halide was once reportedly under consideration as an acquisition target for Apple, a claim that remains unverified.
Foldables and third-party apps
The iPhone Duo’s arrival has prompted third-party developers to rethink app design for foldable hardware. Earlier reporting from iFixit highlighted the device’s repairability advantages and risks, including vulnerabilities in its hinge and inner screen, which could influence long-term user adoption. While the Duo’s market impact is still unclear, Halide’s update reflects a broader trend of developers experimenting with niche features to cater to early adopters of foldable technology.
What this means
Lazyfounder analysis — our interpretation, not reported fact.
Halide’s update for the iPhone Duo signals how third-party developers are adapting to foldable hardware. For founders and operators, this is a case study in tailoring niche software to new form factors—especially premium devices like the Duo, which may attract professional or prosumer users. The waist-level viewfinder feature, in particular, shows how legacy photography techniques can be reimagined for modern devices, offering a potential differentiator in a crowded app market.
The update also underscores the importance of early adoption for foldables. While Apple’s foldable market share remains uncertain, Lux Optics is betting on long-term demand by investing in Duo-specific features. For startups eyeing the foldable ecosystem, this move highlights the opportunity to cater to users who prioritize specialized functionality over generic apps.
Key takeaways
- Third-party apps optimizing for foldables may gain an edge in professional or niche markets like photography.
- Features borrowed from traditional photography (e.g., waist-level viewfinders) can differentiate apps in crowded categories.
- Early investment in foldable-specific updates could position startups favorably if demand for these devices grows.
- Apple’s reported interest in Halide suggests the company may still explore acquisitions in camera-related software, which could influence M&A strategies in the space.
