Features interactive formula triangles that provide a visual aid for solving complex mole-based equations. ## What's New - **Latest (v9.1.240, 1 months ago):** Minor content updates and bug fixes. - **Last Major (v1.1, 11 months ago):** Introduced Element of the Day, expanded chemistry resources, and added support for Widgets and watchOS. ## App Momentum (Maintenance) {#momentum} - Updated Android build in April 2026. - Maintained iOS pricing since August 2024. > **Cadence:** 2 total versions · 1 majors in last 6 months · 36 days since last update · 313 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Periodic Table: Chemistry is an established education app that is free with in-app purchases. > **Bottom Line:** The app succeeds by offering specialized AI-tutor utility, but it loses potential users to free, offline-capable competitors, so the PM should prioritize unifying the pricing model to remove the iOS entry barrier. **Best for:** High school students, college chemistry majors, and professionals requiring quick access to chemical data and problem-solving tools. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] [HIGH IMPACT] Unify pricing model to free-with-IAP because the $1.99 iOS barrier limits top-of-funnel conversion → increase install velocity — *iOS entry fee creates a conversion barrier compared to free Android utility.* _(trade-off: deprioritize Pause the WatchOS feature expansion — pricing unification has higher revenue impact.)_ - [ ] [INVEST] [MEDIUM IMPACT] Ship 'Study Mode' because competitors like Periodic Table 2025 use it to drive retention → improve daily active habit — *Competitor analysis shows structured learning paths are a key differentiator for student retention.* _(trade-off: deprioritize Deprioritize new element data updates — retention is a higher-priority metric.)_ ### Feature Gaps vs Competitors - Study Mode (available in Periodic Table 2025 but missing here) - Offline-first functionality (available in Periodic Table 2025 but missing here) - AR-mapping interface (available in Star Gazer but missing here) ### Outlook: Stable The education reference market is consolidating around high-engagement, free-to-use tools that offer offline accessibility. Periodic Table: Chemistry remains stable but exposed, as its current pricing and feature set fail to address the retention-focused needs of the student demographic. - ⚪ The latest Android update indicates active maintenance, but the lack of new feature additions suggests a focus on stability over growth. - 🔴 The fragmented pricing model between platforms creates inconsistent user acquisition, which limits the app's ability to compete with free, ad-supported incumbents. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Periodic Table: Chemistry** (this app) | N/A/5 | N/A | Adam Nawfal Zekkani | | [GeoForge Academy](https://marlvel.ai/intel-report/education/com-galanisgalactus-geoforgeacademy) | 5.0/5 | N/A | ZACHARY MASON KELLER | | [Astronomy Observer](https://marlvel.ai/intel-report/reference/astronomy-observer) | 4.6/5 | N/A | 雪平 王 | | [Star Gazer & Night Sky Map](https://marlvel.ai/intel-report/education/star-gazer-night-sky-map) | 4.7/5 | Thrilled | Appelio | | [HeartVision](https://marlvel.ai/intel-report/medical/heartvision) | 5.0/5 | N/A | Usama Nasir | | [DrPhos' Stoichiometry](https://marlvel.ai/intel-report/education/drphos-stoichiometry) | 5.0/5 | N/A | Monte L Helm | ## Company Profile - **Developer:** Adam Nawfal Zekkani - **Website:** [https://business.azekkani.com](https://business.azekkani.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/periodic-table-chemistry/id6602892009?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.zakirshikhli.mendeleyevcedveli&hl=en&gl=us) - **Dev Site:** [Official Website](https://business.azekkani.com) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*GeoForge Academy*](https://marlvel.ai/intel-report/education/com-galanisgalactus-geoforgeacademy) (ZACHARY MASON KELLER) — 5.0/5 Rating | N/A Sentiment - [*Astronomy Observer*](https://marlvel.ai/intel-report/reference/astronomy-observer) (雪平 王) — 4.6/5 Rating | N/A Sentiment - [*Star Gazer & Night Sky Map*](https://marlvel.ai/intel-report/education/star-gazer-night-sky-map) (Appelio) — 4.7/5 Rating | Excellent Sentiment - [*HeartVision*](https://marlvel.ai/intel-report/medical/heartvision) (Usama Nasir) — 5.0/5 Rating | N/A Sentiment - [*DrPhos' Stoichiometry*](https://marlvel.ai/intel-report/education/drphos-stoichiometry) (Monte L Helm) — 5.0/5 Rating | N/A Sentiment - [*ChemCalc - Mole Calculator*](https://marlvel.ai/intel-report/education/chemcalc-mole-calculator) (Paul Leadbeater) — N/A Rating | Excellent Sentiment - [*Periodic Table 2025: Chemistry*](https://marlvel.ai/intel-report/education/periodic-table-2025-chemistry) (Darian Orn) — 5.0/5 Rating | Excellent Sentiment - [*Geology Toolkit: Field Guide*](https://marlvel.ai/intel-report/education/geology-toolkit-field-guide) (Laurence Wayne) — 4.6/5 Rating | N/A Sentiment - [*Sourcify*](https://marlvel.ai/intel-report/education/sourcify) (Edomiyas Temesgen) — N/A Rating | N/A Sentiment - [*Planet Patrol*](https://marlvel.ai/intel-report/education/planet-patrol) (Plastic Patrol CIC) — 5.0/5 Rating | N/A 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.
