**Performance Trend:** Stable - **Data Window:** Analysis based on signals collected up to 2026-05-13 ## Executive Snapshot **What it is:** PokéType Chart is a Pokémon battle reference tool for iOS and macOS, featuring type calculators and memorization quizzes. **Why users hire it:** Users hire this app to master battle mechanics, but the 3-day trial gate forces a purchase decision before the tool proves its long-term value. ## App DNA (Features & Intent) - **[Standard] Type Compatibility Calculator:** Tool to investigate move and type effectiveness in Pokémon battles. - **[Standard] Memorization Quizzes:** Interactive quizzes designed to test knowledge of Pokémon type compatibilities. - **[Differentiator] Multi-language Support:** Interface available in eight languages including English, French, German, Italian, Japanese, Korean, Spanish, and Chinese. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. ## Market Position {#market-position} The app operates as a niche utility in the Pokémon GO space, currently limited by a 2-star rating and minimal review volume. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free trial for 3 days after installation, Full access via one-time purchase - **Analysis:** Time-gated freemium model forces a purchase decision 72 hours post-install to maintain access. ## SWOT Analysis {#swot} **Core Strengths:** - Multi-language interface (8 languages) enables broader international reach than single-language competitors. **Critical Frictions:** - 3-day trial gate forces a purchase decision before users establish long-term utility. - 1 total rating indicates low market penetration. **Growth Levers:** - Integration of real-time event tracking could bridge the feature gap with primary market rivals. **Market Threats:** - Established competitors like GO Field Guide maintain community-driven databases that create high switching costs for users. ## Recent Changes (v2 → v3) {#recent-changes} The competitive landscape was refined to focus on GO Field Guide, and the recommended monetization strategy shifted from trial extension to ad-supported freemium. **Overall trend**: Stable **Compared at**: 2026-05-13 ### High-impact changes - **[Shifted] Nemesis Re-alignment** (positioning) — Competitive focus shifted from Poke Genie to GO Field Guide as the primary nemesis, reflecting a closer functional overlap in event-based utility. - **[Shifted] Monetization Strategy Pivot** (pricing) — PM action items shifted from extending the trial duration to implementing an ad-supported freemium model to reduce churn. ### Medium-impact changes - **[Added] Market Penetration Weakness** (swot) — Added '1 total rating' as a specific weakness, highlighting low market penetration. ## Rivals Landscape {#rivals} > Competitive positioning identified by AI analysis of app features, category, and market signals. ### PokéType Chart vs GO Field Guide — Head to Head - **[GO Field Guide](https://marlvel.ai/apps/go-field-guide)** by Sagar Vaghela: This app serves the exact same Pokémon GO utility niche with a massive, established user base and long-term market presence. - **Key differences:** - Provides comprehensive event tracking and raid timers that the target app currently lacks entirely - Maintains a deep community-driven database of Pokémon stats that creates a significant content-based moat - Offers specialized push notifications for limited-time game events to drive daily active user retention ### Peers (What They Do Better) - **[Calculator‰](https://marlvel.ai/apps/calculator-4)** by Tim O's Studios, LLC: While categorized under Utilities, this app operates in a different functional domain and lacks direct thematic overlap with Pokémon type analysis. - Focuses on high-frequency general mathematical utility rather than niche gaming reference data - Leverages massive cross-category reach to maintain visibility without needing specific domain expertise ## What's New - **Latest (v1.0.2, 2 years ago):** Updated and expanded the Pokemon database. ## App Momentum (Zombie) {#momentum} - Released initial version in February 2024. - Maintains standard utility feature set. > **Cadence:** 1 total versions · 0 majors in last 6 months · 818 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} PokéType Chart is an established utilities app that is free with in-app purchases. With a 2/5 rating from 1 reviews, it shows polarized user reception. > **Bottom Line:** PokéType Chart struggles to gain traction due to a restrictive 3-day trial gate, so the PM should pivot to an ad-supported model to build a larger user base before forcing a purchase decision. **Best for:** Pokémon GO players and fans seeking a reference tool to master battle mechanics and type effectiveness. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] [HIGH IMPACT] Pivot the monetization model to a freemium tier with ads because the current 3-day hard lock creates high churn → increase long-term user retention. — *The 3-day trial is the primary friction point for a utility app that needs to build habit.* _(trade-off: deprioritize Pause the one-time purchase conversion testing — ad revenue provides a wider top-of-funnel.)_ - [ ] [INVEST] [MEDIUM IMPACT] Ship event tracking features because the nemesis uses this to dominate the niche → reduce user reliance on competitor tools. — *Competitor analysis shows GO Field Guide uses event tracking to maintain a dominant position.* _(trade-off: deprioritize Deprioritize the quiz-mode expansion — event tracking has higher daily utility for Pokémon GO players.)_ ### Feature Gaps vs Competitors - Real-time event tracking (available in GO Field Guide but absent here) - Raid timers (available in GO Field Guide but absent here) ### Outlook: Stable The Pokémon GO utility market is consolidating around apps that provide comprehensive, free-to-access event data. PokéType Chart remains exposed to churn because its trial model forces a premature purchase decision, so the app must shift to a broader utility model to survive. - 🔴 The restrictive 3-day trial gate limits user acquisition, which prevents the app from building the necessary user base to compete with established rivals. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2/5 | | Total Reviews | 1 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **PokéType Chart** (this app) | 2/5 | N/A | Tatsuya Yamaguchi | | [Calculator‰](https://marlvel.ai/apps/calculator-4) | 4.9/5 | Mixed | Tim O's Studios, LLC | | [GO Field Guide](https://marlvel.ai/apps/go-field-guide) | 4.7/5 | N/A | Sagar Vaghela | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.3/5 | Mixed | Free VPN LLC | | [Quantumult X](https://marlvel.ai/apps/quantumult-x) | 3.8/5 | Frustrated | Cross Utility Ltd | | [Potatso](https://marlvel.ai/apps/potatso) | 4.4/5 | Excited | Potatso Lab LTD | ## Company Profile - **Developer:** Tatsuya Yamaguchi ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/pok%C3%A9type-chart/id6477653930?uo=4) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Calculator‰*](https://marlvel.ai/apps/calculator-4) (Tim O's Studios, LLC) — 4.9/5 Rating | Mixed Sentiment - [*GO Field Guide*](https://marlvel.ai/apps/go-field-guide) (Sagar Vaghela) — 4.7/5 Rating | N/A Sentiment - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) — 4.3/5 Rating | Mixed Sentiment - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) — 3.8/5 Rating | Negative Sentiment - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) — 4.4/5 Rating | Positive Sentiment - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) — 4.5/5 Rating | Positive Sentiment - [*Avoiding Happy Belated*](https://marlvel.ai/apps/avoiding-happy-belated) (Shriansh Shrivastava) — N/A Rating | N/A Sentiment - [*Calculator# Hide Photos Videos*](https://marlvel.ai/apps/calculator-hide-photos-videos) (NewSoftwares.net) — 4.4/5 Rating | N/A Sentiment - [*Nitefall: Browser dark mode*](https://marlvel.ai/apps/nitefall-browser-dark-mode) (FoxfortMobile) — 3.6/5 Rating | N/A Sentiment - [*Modulus Calculator*](https://marlvel.ai/apps/modulus-calculator) (Theodore Dubois) — 4.5/5 Rating | Excellent 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.
