Integrates complex financial formulas that cater to professional and investment-oriented users - Maintains active development with recent updates to keep pace with financial calculation standards - **[% Percentage Calculator](https://marlvel.ai/apps/percentage-calculator-1)** by Hira Akram: A direct functional equivalent that competes for the same specific search intent regarding percentage math. - Focuses exclusively on percentage-based math without the clutter of general-purpose calculator features - Provides a simplified user experience that reduces the time-to-result for basic percentage tasks - **[Percentage Calculator](https://marlvel.ai/apps/percentage-calculator-2)** by Philip Stephens: This app serves the exact same niche as this app, acting as a direct alternative for users seeking simple percentage tools. - Offers a streamlined, single-purpose interface that avoids the complexity of broader financial suites - Positions itself as a dedicated tool for quick, everyday percentage and discount math ### Peers (What They Do Better) - **[ClevCalc - Calculator](https://marlvel.ai/apps/clevcalc-calculator-1)** by Cleveni Inc.: While broader in scope, its massive user base and frequent updates make it a significant adjacent threat in the calculator category. - Provides an all-in-one suite including unit, currency, and complex scientific conversions - Ships frequent feature updates and performance optimizations to maintain its massive install base - **[Splittr - Expense Splitting](https://marlvel.ai/apps/splittr-expense-splitting)** by RWichmann GmbH: Splittr competes for the same utility-focused user base by addressing the 'tip and discount' calculation needs within the broader context of expense management. -

**[groupay - Adjust Split Bill](https://marlvel.ai/apps/groupay-adjust-split-bill)** by Akihiro Usui: This app overlaps with this app's tip and discount functionality by providing specialized tools for bill splitting and settlement. - Allows for selective member payment adjustments, offering granular control that this app currently lacks. - Focuses heavily on settlement calculation workflows, which provides a more streamlined experience for group dining scenarios. - **[Splid – Split group bills](https://marlvel.ai/apps/splid-split-group-bills)** by Nicolas Jersch: Splid is a dominant player in the finance category that captures the same 'quick calculation' audience through its robust bill-splitting ecosystem. - Boasts a massive user base and high review volume, creating a strong network effect for group synchronization. - Provides comprehensive data export features, allowing users to move financial records into external accounting software easily. ### New Kids on the Block (What's Innovative) -

(Strategic Takeaway) {#so-what} Percentage Calculators is a market-leading finance app that is completely free. With a 5/5 rating from 7 reviews, it delivers strong user satisfaction. > **Bottom Line:** Percentage Calculators retains a loyal student base through specialized academic tools, but the lack of bidirectional math logic and infrequent updates creates a churn risk against modern rivals, so prioritize feature parity in the next release to defend the user base. **Best for:** Students, shoppers, and general consumers requiring quick percentage-based math. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship bidirectional calculation logic because it is the primary functional gap vs the nemesis → increase power-user retention ### Feature Gaps vs Competitors - Bidirectional calculation logic (available in Percent Calculator App but missing here) ### Outlook: Stable The percentage-utility market is consolidating around apps that offer both simple tools and advanced bidirectional math logic. Percentage Calculators remains stable due to its academic niche, but the lack of active development leaves it exposed to any rival that combines its specific grading tools with a modern, updated interface. - 🔴 The 183-day update gap signals a maintenance-mode posture, which prevents the app from competing with the nemesis's high-frequency feature release cadence. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 7 | | Sentiment | Thrilled (85/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Mixed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Percentage Calculators** (this app) | 5/5 | Thrilled | Jaydip Jethva | | [Rapid & Quick Calculator Pro](https://marlvel.ai/apps/com-kumade-app-zippycalc-pro) | 4.9/5 | Mixed | KinkumaDesign | | [Financial Calculators](https://marlvel.ai/apps/financial-calculators) | 4.6/5 | N/A | Financept | | [% Percentage Calculator](https://marlvel.ai/apps/percentage-calculator-1) | 4.5/5 | N/A | Hira Akram | | [Percentage Calculator](https://marlvel.ai/apps/percentage-calculator-2) | 4.8/5 | N/A | Philip Stephens | | [groupay - Adjust Split Bill](https://marlvel.ai/apps/groupay-adjust-split-bill) | N/A/5 | N/A | Akihiro Usui | ## Company Profile - **Developer:** Jaydip Jethva - **Website:** [https://jd-app-zone.blogspot.com](https://jd-app-zone.blogspot.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/percentage-calculators/id6450146247?uo=4) - **Dev Site:** [Official Website](https://jd-app-zone.blogspot.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Rapid & Quick Calculator Pro*](https://marlvel.ai/apps/com-kumade-app-zippycalc-pro) (KinkumaDesign) · 4.9/5 Rating - [*Financial Calculators*](https://marlvel.ai/apps/financial-calculators) (Financept) · 4.6/5 Rating - [*% Percentage Calculator*](https://marlvel.ai/apps/percentage-calculator-1) (Hira Akram) · 4.5/5 Rating - [*Percentage Calculator*](https://marlvel.ai/apps/percentage-calculator-2) (Philip Stephens) · 4.8/5 Rating - [*groupay - Adjust Split Bill*](https://marlvel.ai/apps/groupay-adjust-split-bill) (Akihiro Usui) · N/A Rating - [*Fast Tip & Split Calculator*](https://marlvel.ai/apps/fast-tip-split-calculator) (Christopher Romani) · 5.0/5 Rating - [*Splid – Split group bills*](https://marlvel.ai/apps/splid-split-group-bills) (Nicolas Jersch) · 5.0/5 Rating | Excellent Sentiment - [*Splittr - Expense Splitting*](https://marlvel.ai/apps/splittr-expense-splitting) (RWichmann GmbH) · 4.8/5 Rating | Excellent Sentiment - [*ClevCalc - Calculator*](https://marlvel.ai/apps/clevcalc-calculator-1) (Cleveni Inc.) · 4.7/5 Rating | Positive Sentiment - [*Polymarket*](https://marlvel.ai/apps/polymarket) (Polymarket) · 4.1/5 Rating ## 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.
