US Income Tax Calculator remains stable for now, but the lack of active development will likely lead to user attrition as competitors add more sophisticated planning features. - ⚪ The 6-month update cadence suggests a maintenance-only posture, which limits the ability to respond to annual tax law changes. - 🟢 High user ratings (4.76) indicate the core tax-modeling engine is accurate and meets the needs of the current user base. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.76/5 | | Total Reviews | 17 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **US Income Tax Calculator** (this app) | 4.76/5 | N/A | Vista8 Studio Ltd. | | [Polymarket: Trade Live Sports](https://marlvel.ai/apps/polymarket) | 4.5/5 | n/a | Polymarket | | [ATLAS:EARTH - Fun Cashback!](https://marlvel.ai/apps/atlas-earth-fun-cashback) | 4.5/5 | n/a | Atlas Reality, Inc. | | [Banksola: Budget Planner](https://marlvel.ai/apps/banksola-budget-planner) | 4.7/5 | Mixed | Quickdollarapp, Inc | | [Fidelity Investments](https://marlvel.ai/apps/fidelity-investments) | 4.4/5 | n/a | Fidelity Investments | | [Kalshi: Trade Football & more](https://marlvel.ai/apps/kalshi-trade-news-sports) | 4.8/5 | n/a | KalshiEX LLC | ## Company Profile - **Developer:** Vista8 Studio Ltd. - **Website:** [https://vista8studio.com](https://vista8studio.com) ## Data Sources & Links - **App Store ID:** 6751171899 - **Google Play ID:** com.vista8studio.ustaxcalculator - **Dev Site:** [Official Website](https://vista8studio.com) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*Polymarket: Trade Live Sports*](https://marlvel.ai/apps/polymarket) (Polymarket) · 4.5/5 Rating - [*ATLAS:EARTH - Fun Cashback!*](https://marlvel.ai/apps/atlas-earth-fun-cashback) (Atlas Reality, Inc.) · 4.5/5 Rating - [*Banksola: Budget Planner*](https://marlvel.ai/apps/banksola-budget-planner) (Quickdollarapp, Inc) · 4.7/5 Rating - [*Fidelity Investments*](https://marlvel.ai/apps/fidelity-investments) (Fidelity Investments) · 4.4/5 Rating - [*Kalshi: Trade Football & more*](https://marlvel.ai/apps/kalshi-trade-news-sports) (KalshiEX LLC) · 4.8/5 Rating - [*Webull: Investing & Trading*](https://marlvel.ai/apps/webull-investing-trading) (Webull Technologies Pte.
