The developer has also updated FAQ content to acknowledge the lack of custom profile support and direct users to alternatives. **Overall trend**: Declining **Compared at**: 2026-08-28 ### High-impact changes - **[Declined] Outlook Trend Downgrade** (positioning) - **[Shifted] Competitive Narrative Hardening** (positioning) ### Medium-impact changes - **[Shifted] Threat Profile Refinement** (swot) - **[Added] FAQ Transparency** (features) ## What's New - **Latest (v10.5, 2 weeks ago):** Version 10.5 introduces updates to subscription management, onboarding flows, and general app experience. ## App Momentum (Maintenance) {#momentum} - Ships bug fixes only. - Last major release August 2026. > **Cadence:** 1 total versions · 1 majors in last 6 months · 19 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Simple DoF Calculator is a photo & video app that is free with in-app purchases. With a 4.61/5 rating from 102 reviews, it shows mixed user reception. > **Bottom Line:** Updating the camera database would address the primary driver of negative sentiment, which is currently eroding the app's value proposition for professional users. **Best for:** Professional photographers, videographers, and focus pullers requiring precise optical calculations for various camera systems. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship custom camera profile creation because the current rigid database is the #1 driver of negative sentiment → reduce churn among professional users. ### Outlook: Declining The market for optical utility apps is consolidating around tools that offer frequent database updates and community-driven features. Simple DoF Calculator's current maintenance-only posture leaves it exposed to rivals that can better accommodate the rapid release cycles of modern camera manufacturers. - 🔴 The maintenance-only update cadence fails to include recent camera models, which erodes the app's relevance for professional photographers who upgrade gear annually. - 🔴 Lack of developer communication regarding feature requests leads to a perception of abandonment, which increases the likelihood of users migrating to more active alternatives. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.61/5 | | Total Reviews | 102 | | Sentiment | Mixed (55/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Simple DoF Calculator** (this app) | 4.61/5 | Mixed | Dennis van den Berg | | [Cantina: AI Video & Characters](https://marlvel.ai/apps/is-signal-ios) | 4.8/5 | N/A | Cantina, Inc | | [CapCut: Photo & Video Editor](https://marlvel.ai/apps/capcut-photo-video-editor) | 4.1/5 | Mixed | Bytedance Pte.

Yes, it is designed for professionals, but the current database lacks recent camera models, which may limit its utility for those using the latest equipment. ### Does Simple DoF Calculator support custom camera profiles? Currently, the app relies on a pre-loaded database of camera models and does not support user-defined custom profiles. ### What are the limitations of the measurement display? The app currently displays depth of field in decimal feet, which some users find difficult to interpret for macro photography, as it lacks a fractional inch toggle. ### Are there alternatives for photographers using newer cameras? Users seeking support for the latest camera releases should consider tools that offer more frequent database updates, as Simple DoF Calculator is currently in a maintenance-only release cycle. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
