**[Unit Converter Pro](https://marlvel.ai/intel-report/productivity/unit-converter-pro)** by Oyku Gul Imran: This app competes for the productivity-focused user who requires both calculation and conversion capabilities in a single environment. - Allows for complex expression input, enabling users to perform math directly within the conversion interface. - Supports user-defined units, providing a high degree of customization for specialized professional or hobbyist needs. - **[Multi Units Converter](https://marlvel.ai/intel-report/utilities/multi-units-converter)** by Abin Joseph: This app shares the same utility category, focusing on the conversion aspect of mathematical tools that often complements standard calculators. - Supports full offline functionality, ensuring users can perform conversions without needing an active internet connection. - Displays multiple units simultaneously, reducing the number of taps required to compare different measurement standards. ## What's New - **Latest (v1.1.233, 3 years ago):** Added light/dark mode support and customizable button colors. ## App Momentum (Maintenance) {#momentum} - Last major update May 2025. - No new features added recently. > **Cadence:** 5 total versions · 1 majors in last 6 months · 356 days since last update · 82 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Cuspart: Calculator is an established utilities app that is completely free. With a 5/5 rating from 1 reviews, it shows polarized user reception. > **Bottom Line:** Cuspart offers a clean, accessible interface that appeals to casual users, but it lacks the persistent history and platform integrations required to compete with category leaders, so the PM must prioritize a persistent history tape to drive retention. **Best for:** Students, engineers, and general users requiring a scientific calculator with a customizable interface. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Ship persistent history tape because it is the primary retention gap against Calculator⁼ → increase daily active usage — *Calculator⁼ uses a persistent history tape to drive daily return, a feature currently missing in Cuspart.* _(trade-off: deprioritize Pause the color-theme expansion sprint — history-tape utility has a higher impact on retention.)_ - [ ] [PIVOT] [MEDIUM IMPACT] Integrate Apple Watch support because CalcFast uses it to capture on-the-go power users → improve competitive parity — *CalcFast uses wearable integration to challenge the target's utility positioning.* _(trade-off: deprioritize Deprioritize the Constants Library expansion — wearable reach is a higher-value acquisition lever.)_ ### Feature Gaps vs Competitors - Persistent history tape (available in Calculator⁼ but absent here) - Live currency conversion (available in Calculator⁼ but absent here) - Apple Watch integration (available in CalcFast but absent here) ### Outlook: Mixed The utility calculator market is consolidating around apps that offer persistent history and cross-platform integration, leaving Cuspart exposed as a lightweight alternative. Without adding core utility, the app will struggle to convert casual users into a sticky base, so the PM must shift from aesthetic updates to functional retention loops. - 🔴 The lack of persistent history features forces power users toward rivals, which accelerates churn pressure into the next quarter. - ⚪ Recent updates focused on maintenance, no new feature expansion suggests the app is currently in a stable, low-velocity state. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 1 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Cuspart: Calculator** (this app) | 5/5 | N/A | Mustafa Tolga DALBUDAK | | [Dash Calc: Simple Fast Math](https://marlvel.ai/intel-report/utilities/dash-calc-simple-fast-math) | 5.0/5 | Thrilled | Enbright LLC | | [Aspect Ratio Pro](https://marlvel.ai/intel-report/utilities/aspect-ratio-pro) | 4.0/5 | N/A | App ahead GmbH | | [Fractions Calculator Large](https://marlvel.ai/intel-report/utilities/fractions-calculator-large) | 4.5/5 | N/A | Corporate Smalltalk Consulting Ltd | | [Calculator⁼](https://marlvel.ai/intel-report/utilities/calculator-15) | 4.6/5 | Mixed | Impala Studios | | [Unit Converter For Engineers](https://marlvel.ai/intel-report/utilities/unit-converter-for-engineers) | 5.0/5 | N/A | Amanuel Abebaw | ## Company Profile - **Developer:** Mustafa Tolga DALBUDAK ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/cuspart-calculator/id1546543143?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*Dash Calc: Simple Fast Math*](https://marlvel.ai/intel-report/utilities/dash-calc-simple-fast-math) (Enbright LLC) — 5.0/5 Rating | Excellent Sentiment - [*Aspect Ratio Pro*](https://marlvel.ai/intel-report/utilities/aspect-ratio-pro) (App ahead GmbH) — 4.0/5 Rating | N/A Sentiment - [*Fractions Calculator Large*](https://marlvel.ai/intel-report/utilities/fractions-calculator-large) (Corporate Smalltalk Consulting Ltd) — 4.5/5 Rating | N/A Sentiment - [*Calculator⁼*](https://marlvel.ai/intel-report/utilities/calculator-15) (Impala Studios) — 4.6/5 Rating | Mixed Sentiment - [*Unit Converter For Engineers*](https://marlvel.ai/intel-report/utilities/unit-converter-for-engineers) (Amanuel Abebaw) — 5.0/5 Rating | N/A Sentiment - [*CalcFast*](https://marlvel.ai/intel-report/utilities/calcfast) (Hannes Sverrisson) — 4.2/5 Rating | N/A Sentiment - [*Multi Units Converter*](https://marlvel.ai/intel-report/utilities/multi-units-converter) (Abin Joseph) — 5.0/5 Rating | N/A Sentiment - [*Quick Unit Converter: All in 1*](https://marlvel.ai/intel-report/productivity/quick-unit-converter-all-in-1) (Moaaz Afzal) — 5.0/5 Rating | N/A Sentiment - [*Unit Converter Pro*](https://marlvel.ai/intel-report/productivity/unit-converter-pro) (Oyku Gul Imran) — 4.7/5 Rating | Positive Sentiment - [*Free VPN by Free VPN .org™*](https://marlvel.ai/intel-report/utilities/free-vpn-by-free-vpn-org) (Free VPN LLC) — 4.3/5 Rating | Mixed 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.
