US Market. No publisher influence. > **Key Insight:** Fuel Density and Volume Calc is a productivity app by Obli Nishanth Oblirajan. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Productivity | | **Developer** | Obli Nishanth Oblirajan | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.05/1.0) | | **Data Age** | 50d | ## Metadata & Market Performance - **Publisher:** Obli Nishanth Oblirajan - **Category:** Productivity - **Target Audience:** Fuel retail outlet operators and site managers requiring manual volume and density verification. - **Platforms:** iOS - **Version Reviewed:** 1.0.6 - **Report Date:** 2026-08-15 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.05/1.0) - **App Store ID (iOS):** 1606666157 - **Bundle ID:** com.zaptrapp.fueldensityvolume - **Performance Trend:** Stable - **Data Window:** Analysis based on signals collected up to 2026-08-15 ## Executive Snapshot **What it is:** Fuel Density and Volume Calc is a productivity utility for fuel retail operators to calculate density and tank volume on iOS. **Why users hire it:** The tool removes the cognitive friction of manual ASTM 53B table lookups and dip-reading calculations for site managers at specific retail outlets. ## App DNA (Features & Intent) - **[Standard] ASTM 53B Density Calculation:** Calculates fuel density at 15°C based on the ASTM 53B standard. - **[Differentiator] Tank Volume Estimation:** Calculates volume based on cm dip readings for specific BPCL tank capacities. - **[Differentiator] Custom Tank Configuration:** Allows users to input custom tank dimensions to calculate dip values. * *User Intent:* Users value self-expression and personalized experiences. ## Market Position {#market-position} Fuel Density and Volume Calc serves a highly specific B2B-adjacent segment within the productivity category. The lack of updates for over 1,200 days indicates a static market position that relies entirely on its niche utility for BPCL operators. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The tool is distributed as a free utility with no monetization or subscription gates. ## SWOT Analysis {#swot} **Core Strengths:** - ASTM 53B logic provides immediate utility for BPCL operators - Custom tank configuration enables site-specific volume estimation **Growth Levers:** - Digital logbook export would improve site management workflows - Expansion to non-BPCL tank standards would increase addressable market ## Recent Changes (v2 → v3) {#recent-changes} The app remains in a static, maintenance-only state with no changes to features or pricing. The primary shift is an expanded analytical framework that now explicitly categorizes the lack of data export and the rise of web-based alternatives as material risks. **Overall trend**: Stable **Compared at**: 2026-08-15 ### High-impact changes - **[Added] Expanded SWOT Analysis** (swot) ### Medium-impact changes - **[Shifted] Outlook and PM Action** (positioning) ## What's New - **Latest (v1.0.6, 3 years ago):** Addressed keyboard responsiveness and general bug fixes. ## App Momentum (Zombie) {#momentum} - Maintenance-only cadence for 42 months. - Last major release February 2023. > **Cadence:** 1 total versions · 0 majors in last 6 months · 1266 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Fuel Density and Volume Calc is a productivity app that is completely free. > **Bottom Line:** Fuel Density and Volume Calc provides a functional, static utility for BPCL site managers, but the multi-year development freeze leaves the tool vulnerable to OS-level deprecation. A maintenance-only posture is appropriate unless the developer intends to add data-export features that justify a transition to a modern, cloud-connected workflow. **Best for:** Fuel retail outlet operators and site managers requiring manual volume and density verification. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit OS compatibility because the app has not been updated in 1,266 days → prevent sudden app store removal ### Outlook: Stable The outlook for Fuel Density and Volume Calc is stable, as it serves a narrow, unchanging industrial need. The PM should monitor OS compatibility, as the primary risk is not competitive displacement but platform-level deprecation due to the extended development freeze. - ⚪ The 1,266-day update gap suggests the developer views the tool as a finished utility rather than an active product. - ⚪ Static utility tools for niche industrial standards often maintain long-term relevance without frequent updates, provided they remain compatible with current OS versions. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Fuel Density and Volume Calc** (this app) | N/A/5 | N/A | Obli Nishanth Oblirajan | | [Mitsu: AI Life Coach](https://marlvel.ai/apps/mitsu-ai-life-coach) | N/A/5 | N/A | C2 Insights | | [ChatGPT](https://marlvel.ai/apps/chatgpt) | 4.8/5 | n/a | OpenAI OpCo, LLC | | [HitWave](https://marlvel.ai/apps/ciendor-applications-hitwave) | 2.6/5 | Mixed | Ciendor Holdings Corp.
