The lack of recent feature updates relative to the 2015 release date signals a maintenance-only posture. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all logbook features - **Analysis:** The app operates on a free model with no visible IAP or subscription gates, relying on user-contributed data to maintain the site database. ## SWOT Analysis {#swot} **Core Strengths:** - Partner verification via social integration creates a viral loop for new user acquisition - Map-based dive site database functions as a B2B distribution barrier through user-contributed content **Growth Levers:** - Integration with popular dive computer hardware would unlock a high-retention data-sync workflow - Monetization of the dive site database via partnerships with dive resorts could provide a revenue stream ## Recent Changes (v2 → v3) {#recent-changes} The analysis shifted from a focus on monetization to a focus on technical retention, specifically identifying the lack of wearable-sync as the primary competitive disadvantage. **Overall trend**: Stable **Compared at**: 2026-08-09 ### High-impact changes - **[Shifted] Wearable-sync focus** (swot) - **[Shifted] PM action item priority** (positioning) ### Medium-impact changes - **[Shifted] Value proposition refinement** (positioning) ## What's New - **Latest (v3.4.3, 2 months ago):** Fixed a critical error affecting users with large record sets. ## App Momentum (Maintenance) {#momentum} - Ships bug fixes only, no features - Last major release over two months ago > **Cadence:** 1 total versions · 0 majors in last 6 months · 77 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Diving logbook-Dive Number is a sports app that is completely free. It holds a 4.22/5 rating from 95 reviews. > **Bottom Line:** Diving Logbook-Dive Number retains users through a simple, free-to-use interface, but its lack of active development and wearable integration creates a churn risk, so the PM should prioritize a hardware-sync roadmap to defend the user base. **Best for:** Scuba divers seeking a digital alternative to paper logbooks for tracking technical dive data and marine life encounters. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit wearable-sync API feasibility because manual entry is the top churn risk → increase retention ### Outlook: Stable The scuba logbook market is shifting toward automated data ingestion from dive computers, leaving manual-entry apps like this one exposed. The current maintenance posture will likely result in a slow decline in active users as technical divers prioritize platforms that reduce data-entry friction. - ⚪ Recent updates focused on stability, no feature expansion, which limits the app's ability to compete with modern automated logging solutions. - 🔴 The 77-day update gap indicates a maintenance-mode posture, which risks losing market share to competitors with faster development cycles. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.22/5 | | Total Reviews | 95 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Diving logbook-Dive Number** (this app) | 4.22/5 | N/A | Denys Dykusha | | [DraftKings Predictions](https://marlvel.ai/apps/draftkings-predictions) | 4.8/5 | Mixed | DraftKings | | [DraftKings: Sports & Casino](https://marlvel.ai/apps/draftkings-sportsbook-casino) | 4.8/5 | n/a | DraftKings | | [FanDuel Predicts](https://marlvel.ai/apps/fanduel-predicts) | 4.8/5 | n/a | FanDuel, Inc. | | [Fish AI - AI Fishing App](https://marlvel.ai/apps/com-fishai-app) | 4.7/5 | n/a | GymBros Inc. | | [NBA: Live Games & Scores](https://marlvel.ai/apps/nba-live-games-scores) | 4.5/5 | n/a | NBA MEDIA VENTURES, LLC | ## Company Profile - **Developer:** Denys Dykusha - **Website:** [https://divenumber.com](https://divenumber.com) - **Social:** [Instagram](https://www.instagram.com/p) · [Facebook](https://www.facebook.com/divenumber) · [YouTube](https://www.youtube.com/channel/UCh5wUnbSMI0XGInr3wAvi9g) ## Data Sources & Links - **App Store ID:** 949480835 - **Dev Site:** [Official Website](https://divenumber.com) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*DraftKings Predictions*](https://marlvel.ai/apps/draftkings-predictions) (DraftKings) · 4.8/5 Rating - [*DraftKings: Sports & Casino*](https://marlvel.ai/apps/draftkings-sportsbook-casino) (DraftKings) · 4.8/5 Rating - [*FanDuel Predicts*](https://marlvel.ai/apps/fanduel-predicts) (FanDuel, Inc.) · 4.8/5 Rating - [*Fish AI - AI Fishing App*](https://marlvel.ai/apps/com-fishai-app) (GymBros Inc.) · 4.7/5 Rating - [*NBA: Live Games & Scores*](https://marlvel.ai/apps/nba-live-games-scores) (NBA MEDIA VENTURES, LLC) · 4.5/5 Rating - [*PrizePicks - Sports Picks*](https://marlvel.ai/apps/prizepicks-sports-picks) (SidePrize, LLC) · 4.5/5 Rating - [*Sporttrade: Prediction Markets*](https://marlvel.ai/apps/sporttrade-prediction-markets) (SPORTTRADE INC) · 4.7/5 Rating | Positive Sentiment - [*플레이공*](https://marlvel.ai/apps/com-tychesoft-playball) (Tychesoft) · N/A Rating - [*더블이글 - 요즘 골프예약*](https://marlvel.ai/apps/com-albatrss-de) (Double Eagle Inc.) · 4.0/5 Rating - [*테니스타운*](https://marlvel.ai/apps/com-momzit-tennistown) (link.tennistown) · 3.5/5 Rating ## 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.
