No major feature updates since 2021. - Maintenance-only posture limits user growth. > **Cadence:** 2 total versions · 0 majors in last 6 months · 36 days since last update · 1718 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Periodic Table is an established education app that is completely free. With a 4.28/5 rating from 191 reviews, it shows polarized user reception. > **Bottom Line:** The app holds its category lead through institutional trust but bleeds users to interactive, high-fidelity alternatives, so revenue and engagement growth hinge on pivoting from a static reference to an interactive learning tool. **Best for:** Students, teachers, and individuals interested in chemical sciences seeking a reference tool. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Ship 3D atomic visualization module because static 2D tables are losing users to 3D-centric competitors → increase session duration — *Competitors like EleMend- 3D Periodic Table provide spatial understanding that the current 2D interface lacks.* _(trade-off: deprioritize Deprioritize the podcast library expansion — 3D visualization has higher impact on modernizing the core user experience.)_ ### Feature Gaps vs Competitors - 3D atomic visualization (available in EleMend- 3D Periodic Table but absent here) - Real-time AR celestial mapping (available in Star Walk 2 Pro but absent here) - Gamified progress tracking (available in GeoForge Academy but absent here) ### Outlook: Declining The educational reference market is consolidating around interactive, high-fidelity tools that prioritize engagement over static data. The subject app's maintenance-only posture leaves it exposed to agile rivals, so the PM must pivot to interactive features or risk total irrelevance. - 🔴 The lack of iOS updates since 2021 signals a maintenance-mode posture, which erodes the app's relevance against competitors with monthly release cadences. - 🔴 Competitors like EleMend- 3D Periodic Table capture the student demographic by offering 3D visualization, which directly drains the subject app's user base. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.28/5 | | Total Reviews | 191 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Periodic Table** (this app) | 4.28/5 | N/A | Royal Society of Chemistry | | [Star Walk 2 Pro: Sky Map Live](https://marlvel.ai/intel-report/education/com-vitotechnology-starwalk2) | 4.7/5 | Mixed | Vito Technology Inc. | | [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 | | [Vernier Graphical Analysis](https://marlvel.ai/intel-report/education/vernier-graphical-analysis) | 2.1/5 | Mixed | Vernier Software & Technology | ## Company Profile - **Developer:** Royal Society of Chemistry ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/periodic-table/id1019468967?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.zakirshikhli.mendeleyevcedveli&hl=en&gl=us) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Star Walk 2 Pro: Sky Map Live*](https://marlvel.ai/intel-report/education/com-vitotechnology-starwalk2) (Vito Technology Inc.) — 4.7/5 Rating | Mixed Sentiment - [*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 - [*Vernier Graphical Analysis*](https://marlvel.ai/intel-report/education/vernier-graphical-analysis) (Vernier Software & Technology) — 2.1/5 Rating | Mixed Sentiment - [*Vernier Spectral Analysis*](https://marlvel.ai/intel-report/education/vernier-spectral-analysis) (Vernier Software & Technology) — 2.2/5 Rating | N/A Sentiment - [*ChemCalc - Mole Calculator*](https://marlvel.ai/intel-report/education/chemcalc-mole-calculator) (Paul Leadbeater) — N/A Rating | Excellent Sentiment - [*Labster*](https://marlvel.ai/intel-report/education/labster) (Labster) — 2.8/5 Rating | N/A Sentiment - [*Plant Life - Science for Kids*](https://marlvel.ai/intel-report/education/plant-life-science-for-kids) (Tappity, Inc.) — 4.5/5 Rating | N/A Sentiment - [*EleMend- 3D Periodic Table*](https://marlvel.ai/intel-report/education/elemend-3d-periodic-table) (ZipoApps) — 4.7/5 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.
