For iPhone photographers seeking long exposure capabilities without physical ND filters or post-processing.
What does it look like?
Key features
Blends camera frames using Metal compute shaders to simulate long exposure effects without an ND filter.
Uses median blending to automatically detect and remove moving objects from static scenes.
Provides granular adjustment of ISO, focus, and shutter duration for precise exposure management.
How much does it cost?
The freemium model gates advanced formats and unlimited duration behind a $14.99 annual subscription or $29.99 lifetime purchase.

Maintenance developmentUX improvementsperformanceShow more...
With only two releases in the observed window and a cadence that falls into the maintenance tier, development is currently focused on stability and UX refinements. The latest version addresses specific friction points regarding photo access permissions, purchase restoration, and camera error reporting. There is no evidence of new feature development or live operations, as the team is prioritizing the resolution of existing technical hurdles. The current pace suggests a stable, low-frequency maintenance cycle.

Key takeaways for Lento: Long Exposure Camera
Where is it heading?
The long-exposure utility market is consolidating around apps that offer both ease of use and professional-grade RAW output. Lento remains advantaged by its Metal-accelerated real-time preview, but the maintenance-only update cadence leaves it exposed to rivals that ship frequent live-ops updates.
- The latest release focuses on stability and purchase restoration, indicating a maintenance-only cadence rather than aggressive feature expansion.
The SWOT
- GPU-accelerated Metal compute shaders enable real-time preview
- Manual control suite provides professional-grade exposure management
- Localized pricing untapped in high-ARPU international markets
Next best moves
A/B test regional pricing because the $14.99 annual fee is uniform globally → increase conversion in price-sensitive markets
