Depth of Field Calc is a technical photography utility for iOS that calculates depth-of-field and hyperfocal distances using a visual lens-barrel interface.
The App DNA
What makes this app unique?
Photographers use the app to replace mental math and generic calculators with a precise, visual reference that maps directly to manual lens operation.
For Photographers and photography students requiring precise technical calculations for depth of field, hyperfocal distance, and focus stacking.
What does it look like?
Key features
Visualizes depth-of-field scale in real time as a green zone on a simulated lens barrel.
Calculates frame count and per-frame focus distance for macro photography with 20% overlap.
Traffic light indicator based on the selected camera body's pixel pitch.
How much does it cost?
The freemium model uses a one-time purchase to gate advanced technical planning tools while keeping core utility free to maximize the user base.

Key takeaways for Depth of Field Calc
Where is it heading?
The technical utility market is consolidating around tools that offer both precision and frequent live-ops updates. Depth of Field Calc remains advantaged by its visual interface, but the lack of recent development activity leaves the app exposed to rivals that maintain a more active release schedule.
- The 106-day gap since the last update signals a transition to maintenance mode, which reduces the app's visibility in competitive search results.
- The high-utility free tier provides a strong foundation for organic discovery, which could support future growth if the development cadence resumes.
The SWOT
- Live clarity band visualization creates a defensible differentiation against standard text-based calculators
- Strict millimeter unit discipline ensures professional-grade accuracy for technical photography
- Educational partnerships with photography schools could leverage the app's built-in plain-language explainers
Next best moves
Ship a minor feature update because the app has been in maintenance mode for over three months → defend against active rivals
The counter-intuitive read
The app's maintenance-mode status is a feature, not a bug…
Read the full takeBottom line
Depth of Field Calc secures a niche by prioritizing visual feedback over raw data, but the current maintenance-mode cadence risks stagnation. A minor feature update would defend the tool's relevance against more active technical utilities.
