The lack of traction on iOS (1 rating) indicates a single-platform dependency that limits total addressable market reach. ## Monetization Strategy - **Model:** Free - **Tiers:** Free, ad-supported version - **Analysis:** The app utilizes an ad-supported free model with no IAP or subscription gates, monetizing through high-volume traffic. ## SWOT Analysis {#swot} **Core Strengths:** - Offline-first engine ensures utility in remote field environments - Broad geometry support covers diverse industrial and hobbyist use cases **Growth Levers:** - Integrate material-specific density databases to increase professional stickiness - Add PDF export for professional documentation ## Recent Changes (v2 → v3) {#recent-changes} The app's functional state remains unchanged, but the competitive assessment has shifted to emphasize vertical-specific utility gaps and professional documentation needs. **Overall trend**: Mixed **Compared at**: 2026-05-26 ### High-impact changes - **[Added] Professional feature gaps identified** (swot) - **[Shifted] Competitive landscape focus** (positioning) ### Medium-impact changes - **[Improved] Review volume increase** (sentiment) ## What's New - **Latest (v1.01, 1 years ago):** Addressed minor bugs. ## App Momentum (Maintenance) {#momentum} - Ships maintenance updates for Android. - Maintains stable 4.71 rating. > **Cadence:** 2 total versions · 0 majors in last 6 months · 3 days since last update · 594 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Tank Volume Calculator is an established utilities app that is completely free. It holds a 4.71/5 rating from 11K reviews. > **Bottom Line:** Tank Volume Calculator holds a strong Android rating through simple, offline utility, but it lacks the technical depth to defend against vertical-specific competitors, so the PM should prioritize professional export features to increase stickiness. **Best for:** Professionals in agriculture, oil and gas, and water management, alongside home aquarium enthusiasts. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship PDF export functionality because professional users require documentation for compliance → increase professional retention ### Feature Gaps vs Competitors - Material-specific density databases (available in Moro AgriExpert) ### Outlook: Stable The utility calculator market is consolidating around specialized, vertical-specific tools that offer more than just volume math. Tank Volume Calculator remains stable on Android, but it must evolve beyond basic geometry to retain professional users who are increasingly moving toward apps that provide reporting and material-specific data. - ⚪ The app maintains a stable Android rating, indicating that the current feature set meets basic user needs without significant churn. - 🔴 The lack of iOS presence and professional export tools leaves the app vulnerable to vertical-specific competitors that offer deeper domain utility. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.71/5 | | Total Reviews | 11K | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Tank Volume Calculator** (this app) | 4.71/5 | N/A | Bestami Oktay Akpinar | | [Build Specs](https://marlvel.ai/apps/build-specs) | N/A/5 | N/A | Luke Kazmierowicz | | [Moro AgriExpert Farm Calc](https://marlvel.ai/apps/moro-agriexpert-farm-calc) | N/A/5 | N/A | BMAC INFOTECH | | [Orenda](https://marlvel.ai/apps/orenda) | 4.7/5 | Excited | Hasa Inc. | | [Time Calculator ×](https://marlvel.ai/apps/time-calculator) | 4.7/5 | Excited | DOUBLE U s.r.o. | | [Protractor+](https://marlvel.ai/apps/protractor-1) | 4.2/5 | Mixed | Tue Nguyen Minh | ## Company Profile - **Developer:** Bestami Oktay Akpinar ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/tank-volume-calculator/id6727014725?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.pixelsdo.tankvolumecalculator&hl=en&gl=us) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Build Specs*](https://marlvel.ai/apps/build-specs) (Luke Kazmierowicz) · N/A Rating - [*Moro AgriExpert Farm Calc*](https://marlvel.ai/apps/moro-agriexpert-farm-calc) (BMAC INFOTECH) · N/A Rating - [*Orenda*](https://marlvel.ai/apps/orenda) (Hasa Inc.) · 4.7/5 Rating | Positive Sentiment - [*Time Calculator ×*](https://marlvel.ai/apps/time-calculator) (DOUBLE U s.r.o.) · 4.7/5 Rating | Positive Sentiment - [*Protractor+*](https://marlvel.ai/apps/protractor-1) (Tue Nguyen Minh) · 4.2/5 Rating - [*kVA (Single and Three Phase)*](https://marlvel.ai/apps/kva-single-and-three-phase) (Webtoweb) · 4.2/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.4/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.5/5 Rating | Positive Sentiment - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating | Positive Sentiment ## 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.
