(Strategic Takeaway) {#so-what} Resale Profit Calculator is a business app that is completely free. > **Bottom Line:** Resale Profit Calculator provides a clear utility for profit-conscious sellers, but the 154-day development silence leaves it vulnerable to platform-native tools. Automating fee-rate lookups would lock in the core user base and defend against general-purpose spreadsheet alternatives. **Best for:** Individual marketplace sellers who need to calculate net profit after accounting for platform fees and shipping expenses. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit platform fee structures because the current manual input model is prone to user error → increase calculation accuracy ### Outlook: Stable The market for niche seller utilities is consolidating around tools that integrate directly with marketplace APIs to automate fee calculations. Resale Profit Calculator remains a static utility, which will likely lead to user churn if it fails to adapt to changing platform commission models. - 🔴 The 154-day update gap indicates a maintenance-only posture, which risks obsolescence as marketplace fee structures change. ## 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 | | :--- | :--- | :--- | :--- | | **Resale Profit Calculator** (this app) | N/A/5 | N/A | Toshimasa Matake | | [Groupon Merchant](https://marlvel.ai/apps/groupon-merchant) | 3.0/5 | n/a | Groupon, Inc. | | [긱톡 - 재택부업, 프리랜서, 단기알바 정보 플랫폼](https://marlvel.ai/apps/com-gigtalk-gigtalk) | 4.5/5 | N/A | Nextstep Inc. | | [두란노](https://marlvel.ai/apps/app--971) | N/A/5 | N/A | Duranno | | [쿠펀치](https://marlvel.ai/apps/coupang-app-coupunch) | 1.0/5 | N/A | Coupang Corp. | | [아지트 - 함께 소통하는 업무용 커뮤니티](https://marlvel.ai/apps/app--797) | 3.0/5 | N/A | Kakao Corp. | ## Company Profile - **Developer:** Toshimasa Matake - **Website:** [https://mt-0509.github.io/](https://mt-0509.github.io/) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/resale-profit-calculator/id6758228704?uo=4) - **Dev Site:** [Official Website](https://mt-0509.github.io/) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*Groupon Merchant*](https://marlvel.ai/apps/groupon-merchant) (Groupon, Inc.) · 3.0/5 Rating - [*긱톡 - 재택부업, 프리랜서, 단기알바 정보 플랫폼*](https://marlvel.ai/apps/com-gigtalk-gigtalk) (Nextstep Inc.) · 4.5/5 Rating - [*두란노*](https://marlvel.ai/apps/app--971) (Duranno) · N/A Rating - [*쿠펀치*](https://marlvel.ai/apps/coupang-app-coupunch) (Coupang Corp.) · 1.0/5 Rating - [*아지트 - 함께 소통하는 업무용 커뮤니티*](https://marlvel.ai/apps/app--797) (Kakao Corp.) · 3.0/5 Rating - [*シフオプ*](https://marlvel.ai/apps/shift-management-service-to-support-optimal-placem) (Recruit Co.,Ltd.) · N/A Rating - [*아임히어 - 모바일 출결 관리 앱*](https://marlvel.ai/apps/com-imhere-client-student) (LFin) · 2.9/5 Rating - [*카매니저 - 중고차 딜러전용 전국 매물공유 플랫폼*](https://marlvel.ai/apps/kr-co-autocafe-carmanager) (atonmobility appmaster) · 3.0/5 Rating - [*금호고속 셔틀*](https://marlvel.ai/apps/kr-co-kumhobuslines-shuttle-route-passengernew) (kumhoexpress) · 2.1/5 Rating - [*쿠팡이츠 배달 파트너*](https://marlvel.ai/apps/coupang-eats-delivery) (Coupang Corp.) · 2.6/5 Rating ## Frequently Asked Questions {#faq} ### Is Resale Profit Calculator free to use?
