(Strategic Takeaway) {#so-what} Calculator + is a market-leading utilities app that is free with in-app purchases. With a 4.36/5 rating from 775.4K reviews, it delivers strong user satisfaction. > **Bottom Line:** Calculator + maintains a strong utility core but risks its user base by gating legacy features behind subscriptions, so the PM must prioritize restoring the running total display to stabilize retention before further monetization experiments. **Best for:** Students and professionals requiring both standard arithmetic and advanced mathematical problem-solving capabilities on mobile devices. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Restore the running total display because it is the top-requested feature to reduce churn → improve retention. ### Feature Gaps vs Competitors - Integrated notes and drawing tabs (available in Calculator for iPad! but absent here). ### Outlook: Declining The utility market is consolidating around high-precision tools that offer seamless workspace integration, leaving Calculator + exposed due to its recent feature-removal cycle. Unless the team restores core workflow features like the running total, the app will continue to lose its technical user base to competitors that prioritize consistent utility over aggressive monetization. - 🔴 The removal of the running total display disrupts long-sequence workflows, which directly increases churn among the app's most active power users. - 🔴 Aggressive subscription gating of previously free tools has triggered a cluster of negative reviews, eroding the app's long-standing positive sentiment. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.36/5 | | Total Reviews | 775.4K | | Sentiment | Excited (65/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Calculator +** (this app) | 4.36/5 | Excited | xNeat.com | | [Dash Calc: Simple Fast Math](https://marlvel.ai/apps/dash-calc-simple-fast-math) | 5.0/5 | Thrilled | Enbright LLC | | [Calculator HD+ Pro](https://marlvel.ai/apps/calculator-hd-pro-1) | 4.8/5 | N/A | smalltech sarl | | [iCalc Lite - Calculator](https://marlvel.ai/apps/icalc-lite-calculator) | 4.6/5 | N/A | Gilbert Montane Pinto | | [Basic Calculator: Classic Calc](https://marlvel.ai/apps/basic-calculator-classic-calc) | 4.8/5 | N/A | MobArts | | [Age Calculator – Date Counter](https://marlvel.ai/apps/age-calculator-date-counter) | N/A/5 | N/A | Mustafa Kulac | ## Company Profile - **Developer:** xNeat.com ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/calculator/id351815470?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.google.android.calculator&hl=en&gl=us) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Dash Calc: Simple Fast Math*](https://marlvel.ai/apps/dash-calc-simple-fast-math) (Enbright LLC) · 5.0/5 Rating | Excellent Sentiment - [*Calculator HD+ Pro*](https://marlvel.ai/apps/calculator-hd-pro-1) (smalltech sarl) · 4.8/5 Rating - [*iCalc Lite - Calculator*](https://marlvel.ai/apps/icalc-lite-calculator) (Gilbert Montane Pinto) · 4.6/5 Rating - [*Basic Calculator: Classic Calc*](https://marlvel.ai/apps/basic-calculator-classic-calc) (MobArts) · 4.8/5 Rating - [*Age Calculator – Date Counter*](https://marlvel.ai/apps/age-calculator-date-counter) (Mustafa Kulac) · N/A Rating - [*Unit Converter For Engineers*](https://marlvel.ai/apps/unit-converter-for-engineers) (Amanuel Abebaw) · 5.0/5 Rating - [*Quick Unit Converter: All in 1*](https://marlvel.ai/apps/quick-unit-converter-all-in-1) (Moaaz Afzal) · 5.0/5 Rating - [*Unit Converter Pro*](https://marlvel.ai/apps/unit-converter-pro) (Oyku Gul Imran) · 4.7/5 Rating | Excellent Sentiment - [*Cuspart: Unit Converter*](https://marlvel.ai/apps/cuspart-unit-converter) (Mustafa Tolga DALBUDAK) · 4.5/5 Rating - [*Calculator for iPad!*](https://marlvel.ai/apps/calculator-for-ipad-1) (7th Gear) · 4.7/5 Rating ## Frequently Asked Questions {#faq} ### Is Calculator + free to use?
