Ships ~2 releases per year. - Last major release Jan 2026. > **Cadence:** 2 total versions · 1 majors in last 6 months · 81 days since last update · 57 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Compound Interest Calculator is a finance app that is free with in-app purchases. With a 4.81/5 rating from 6.4K reviews, it shows mixed user reception. > **Bottom Line:** Restoring UI density and fixing navigation crashes would resolve the primary churn drivers, allowing Compound Interest Calculator to leverage its superior UX against the bloated interfaces of its rivals. **Best for:** Retail investors, students, and retirement planners requiring fast, visual financial modeling. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Revert UI scaling changes because user complaints regarding excessive scrolling are the top frustration theme → reduce churn pressure ### Feature Gaps vs Competitors - Inflation-adjusted withdrawals (available in When Can I Retire but absent here) ### Outlook: Declining The financial utility market is consolidating around apps that offer both deep modeling and high-frequency live-ops updates. Compound Interest Calculator's current maintenance-mode cadence and recent stability regressions leave it exposed to rivals that offer more frequent feature parity, which will likely erode its user base if the UI and crash issues are not addressed by Q3. - 🔴 UI regressions and stability issues in the latest release drive negative sentiment, which compounds the rating drag already visible on Android. - ⚪ The app follows a maintenance-only cadence with no significant feature expansion in the last four months, leaving it vulnerable to live-ops rivals. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.81/5 | | Total Reviews | 6.4K | | Sentiment | Mixed (45/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Compound Interest Calculator** (this app) | 4.81/5 | Mixed | Webtoweb | | [10bII Financial Calculator PRO](https://marlvel.ai/apps/com-incpt-mobis-10biifinancialcalculator) | 4.6/5 | Mixed | Incpt.Mobis | | [Unimoni Oman](https://marlvel.ai/apps/com-unimonioman) | 3.9/5 | N/A | Unimoni Exchange LLC | | [Polymarket: Trade Live Sports](https://marlvel.ai/apps/polymarket) | 4.6/5 | n/a | Polymarket | | [Sporttrade: Prediction Markets](https://marlvel.ai/apps/sporttrade-prediction-markets) | 4.7/5 | Excited | SPORTTRADE INC | | [Currency Converter & Exchange](https://marlvel.ai/apps/currency-converter-exchange) | 4.6/5 | Excited | Ajay Gorasiya | ## Company Profile - **Developer:** Webtoweb - **Website:** [https://www.webtoweb.fr](https://www.webtoweb.fr) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/compound-interest-calc/id1509212588?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=calculator.compound.interest&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.webtoweb.fr) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*10bII Financial Calculator PRO*](https://marlvel.ai/apps/com-incpt-mobis-10biifinancialcalculator) (Incpt.Mobis) · 4.6/5 Rating - [*Unimoni Oman*](https://marlvel.ai/apps/com-unimonioman) (Unimoni Exchange LLC) · 3.9/5 Rating - [*Polymarket: Trade Live Sports*](https://marlvel.ai/apps/polymarket) (Polymarket) · 4.6/5 Rating - [*Sporttrade: Prediction Markets*](https://marlvel.ai/apps/sporttrade-prediction-markets) (SPORTTRADE INC) · 4.7/5 Rating | Positive Sentiment - [*Currency Converter & Exchange*](https://marlvel.ai/apps/currency-converter-exchange) (Ajay Gorasiya) · 4.6/5 Rating | Positive Sentiment - [*Financial Calculator: Percent*](https://marlvel.ai/apps/financial-calculator-percent) (Applorium Ltd) · 4.7/5 Rating - [*When Can I Retire*](https://marlvel.ai/apps/when-can-i-retire) (Grow Nest Egg, LLC) · 3.7/5 Rating - [*Cebuana Lhuillier Quikz*](https://marlvel.ai/apps/cebuana-lhuillier-quikz) (Pangea) · 4.5/5 Rating - [*Share Market Calculator*](https://marlvel.ai/apps/share-market-calculator) (Jaydip Jethva) · N/A Rating - [*Bankrate Mortgage Calculator*](https://marlvel.ai/apps/bankrate-mortgage-calculator) (Muhammad Omar Farooq Shah) · N/A 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.
