The absence of updates since 2017 limits its ability to compete with modern, API-driven tax services. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all calculators - **Analysis:** The app is entirely free and serves as a lead-generation tool for the developer's primary tax calculator website. ## SWOT Analysis {#swot} **Core Strengths:** - Multi-country comparison logic functions as a B2B distribution barrier **Growth Levers:** - Introduce premium tiers to monetize high-intent professional users ## What's New - **Latest (v0.0.1, 9 years ago):** Introduced World Tax Calculator to compute and compare taxes across major global economies. ## App Momentum (Zombie) {#momentum} - Dormant since November 2017. - Zero updates in 8 years. > **Cadence:** 2 total versions · 2 majors in last 6 months · 3229 days since last update · 185 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} World Tax Calculator is a finance app that is completely free. > **Bottom Line:** The lack of updates since 2017 makes the current tax calculations unreliable for professional use, necessitating a sunset of the mobile presence to protect the developer's brand reputation on the primary tax-service website. **Best for:** Individuals and professionals seeking to compare tax liabilities and take-home pay across international borders. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the mobile app because the 8-year update gap renders the tax logic obsolete → reduce brand drag ### Outlook: Declining The market for tax utilities is shifting toward real-time, web-native services that integrate directly with government APIs. World Tax Calculator's reliance on static, outdated logic leaves it exposed to churn as users migrate to more reliable, frequently updated alternatives. - 🔴 The 8-year development gap indicates the app is in permanent maintenance mode, which erodes trust in the accuracy of the provided tax calculations. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **World Tax Calculator** (this app) | N/A/5 | N/A | Rayan Arman | | [ATLAS:EARTH - Fun Cashback!](https://marlvel.ai/apps/atlas-earth-fun-cashback) | 4.5/5 | n/a | Atlas Reality, Inc. | | [Banksola: Budget Planner](https://marlvel.ai/apps/banksola-budget-planner) | 4.7/5 | Mixed | Quickdollarapp, Inc | | [코인원 - 가상자산 거래소(비트코인, 이더리움, 테더)](https://marlvel.ai/apps/coinone-co-kr-official) | 3.1/5 | N/A | Coinone | | [다트맨 - 전자공시 푸시알림](https://marlvel.ai/apps/com-coreasset-stockhunter) | 2.1/5 | N/A | ORBIS Investment Advisors Co., Ltd. | | [디지로카(롯데카드)](https://marlvel.ai/apps/com-lcacapp) | 2.5/5 | N/A | lottecard | ## Company Profile - **Developer:** Rayan Arman - **Website:** [https://www.uktaxcalculators.co.uk/world/](https://www.uktaxcalculators.co.uk/world/) - **Social:** [Facebook](https://facebook.com/sharer/sharer.php?u=https) · [X/Twitter](https://twitter.com/intent) ## Data Sources & Links - **App Store ID:** 1230935591 - **Google Play ID:** com.geekycoders.worldtaxcalc - **Dev Site:** [Official Website](https://www.uktaxcalculators.co.uk/world/) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*ATLAS:EARTH - Fun Cashback!*](https://marlvel.ai/apps/atlas-earth-fun-cashback) (Atlas Reality, Inc.) · 4.5/5 Rating - [*Banksola: Budget Planner*](https://marlvel.ai/apps/banksola-budget-planner) (Quickdollarapp, Inc) · 4.7/5 Rating - [*코인원 - 가상자산 거래소(비트코인, 이더리움, 테더)*](https://marlvel.ai/apps/coinone-co-kr-official) (Coinone) · 3.1/5 Rating - [*다트맨 - 전자공시 푸시알림*](https://marlvel.ai/apps/com-coreasset-stockhunter) (ORBIS Investment Advisors Co., Ltd.) · 2.1/5 Rating - [*디지로카(롯데카드)*](https://marlvel.ai/apps/com-lcacapp) (lottecard) · 2.5/5 Rating - [*บเรนนี่ เงินสด*](https://marlvel.ai/apps/com-finance-rennycorpoth) (RENNY CORPORATION COMPANY LIMITED) · N/A Rating - [*ศรีสวัสดิ์*](https://marlvel.ai/apps/com-srisawad-mobileapplications) (Srisawad Power 2014 Company Limited) · 3.8/5 Rating - [*しんきんバンキングアプリ*](https://marlvel.ai/apps/jp-shinkin-ib-banking) (The Shinkin Banks Information System Center Co Ltd) · 3.3/5 Rating - [*10bII+*](https://marlvel.ai/apps/10bii) (Anishu, Inc.) · 2.0/5 Rating - [*10BII Calc HD*](https://marlvel.ai/apps/com-ernestbrock-calc10biihd) (Ernest Brock) · 4.9/5 Rating | Excellent 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.
