This shift acknowledges the market's transition toward community-validated data. **Overall trend**: Stable **Compared at**: 2026-08-30 ### High-impact changes - **[Shifted] Strategic Roadmap Pivot** (positioning) ### Medium-impact changes - **[Added] Taxonomic Update Threat** (swot) - **[Shifted] Market Outlook Update** (positioning) ## What's New - **Latest (v1.5, 1 weeks ago):** Expanded the taxonomy with new species. ## App Momentum (Maintenance) {#momentum} - Ships ~4 releases per year. - Expanded taxonomy in latest release. > **Cadence:** 2 total versions · 1 majors in last 6 months · 9 days since last update · 95 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Tropical Reefs Species Guide is a travel app that is completely free. It holds a 5/5 rating from 7 reviews. > **Bottom Line:** Tropical Reefs Species Guide succeeds by prioritizing utility over monetization, but the maintenance-mode cadence risks obsolescence as marine taxonomy evolves. Shifting toward community-driven data would unlock a retention loop that static reference tools cannot match. **Best for:** Recreational scuba divers, snorkelers, and marine biology enthusiasts. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Implement user-submitted sighting logs because the current static guide lacks community engagement → increase long-term retention ### Outlook: Stable The marine identification market is shifting toward community-validated data, where static guides are increasingly viewed as incomplete. Tropical Reefs Species Guide remains advantaged by its high-fidelity image library, but it must transition to a dynamic data model to avoid being displaced by crowd-sourced alternatives. - ⚪ The maintenance-level release cadence ensures stability but limits the app's ability to respond to rapid taxonomic changes in marine biology. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 7 | | Sentiment | Thrilled (90/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Tropical Reefs Species Guide** (this app) | 5/5 | Thrilled | Florent Charpin | | [กิจวัตรมุสลิมไทย](https://marlvel.ai/apps/th-co-mtel-muslimdailythai) | N/A/5 | N/A | Mudarmeen Munlin | | [108 Divyadesam Navigator](https://marlvel.ai/apps/com-rsunda12-divyadesams) | N/A/5 | N/A | Rajagopal Sundarrajan | | [17 Mile Drive Audio Tour Guide](https://marlvel.ai/apps/17-mile-drive-audio-tour-guide) | 4.5/5 | N/A | 17 Mile Drive Day Trips, LLC | | [1Call Taxi](https://marlvel.ai/apps/1call-taxi) | 5.0/5 | N/A | Ardalan Hussein | | [1st Central Connect](https://marlvel.ai/apps/1st-central-connect) | 3.0/5 | N/A | Cambridge Mobile Telematics Inc. | ## Company Profile - **Developer:** Florent Charpin - **Website:** [https://reefguide.org](https://reefguide.org) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/tropical-reefs-species-guide/id6762312883?uo=4) - **Dev Site:** [Official Website](https://reefguide.org) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*กิจวัตรมุสลิมไทย*](https://marlvel.ai/apps/th-co-mtel-muslimdailythai) (Mudarmeen Munlin) · N/A Rating - [*108 Divyadesam Navigator*](https://marlvel.ai/apps/com-rsunda12-divyadesams) (Rajagopal Sundarrajan) · N/A Rating - [*17 Mile Drive Audio Tour Guide*](https://marlvel.ai/apps/17-mile-drive-audio-tour-guide) (17 Mile Drive Day Trips, LLC) · 4.5/5 Rating - [*1Call Taxi*](https://marlvel.ai/apps/1call-taxi) (Ardalan Hussein) · 5.0/5 Rating - [*1st Central Connect*](https://marlvel.ai/apps/1st-central-connect) (Cambridge Mobile Telematics Inc.) · 3.0/5 Rating - [*247 Airport Transfer*](https://marlvel.ai/apps/247-airport-transfer) (Ionel Tanasa) · N/A Rating - [*24Seven Taxi Driver*](https://marlvel.ai/apps/24seven-taxi-driver) (24Seven Taxi Dispatch, LLC) · 5.0/5 Rating - [*24Seven Taxi Service*](https://marlvel.ai/apps/24seven-taxi-service) (My Taxi Ride Inc.) · N/A Rating - [*2 one day trips Tokyo suburbs*](https://marlvel.ai/apps/2-one-day-trips-tokyo-suburbs) (mlet co.,ltd) · N/A Rating - [*360 Central Park AR NYC Map*](https://marlvel.ai/apps/com-vues-360centralpark) (Vadym Ustymenko) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Tropical Reefs Species Guide free to use?
