## Executive Snapshot
**What it is:** EFB-Pro is an aircraft performance calculator for professional flight crews, providing offline access to AFM-compliant takeoff and landing data on iOS.
**Why users hire it:** It removes the connectivity dependency for critical flight calculations, allowing pilots to maintain regulatory compliance in remote environments where internet access is unavailable.
<!-- /section:executive-snapshot -->

<!-- section:features -->
## App DNA (Features & Intent)
- **[Differentiator] AFM-Compliant Performance Calculator:** Calculates takeoff and landing metrics directly from Aircraft Flight Manual data for turbine aircraft.
  * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior.
- **[Differentiator] Offline Runway Database:** Stores international runway data locally to enable calculations without internet connectivity.
  * *User Intent:* Users want uninterrupted access without internet dependency.
- **[Differentiator] Performance Forecasting (PCast):** Visualizes takeoff distance and climb gradients across temperature ranges in 2C increments.
<!-- /section:features -->

<!-- section:market-position -->
## Market Position {#market-position}

EFB-Pro occupies a niche reference category for professional aviation, maintaining a 5-star rating despite a limited sample of 16 reviews. The lack of updates for over 90 days signals a maintenance-mode posture that leaves the app vulnerable to more agile, modern competitors.
<!-- /section:market-position -->

## Monetization Strategy
- **Model:** Subscription
- **Tiers:** Free app download, Requires active EFB-Mobile account subscription with CAVU Companies
- **Analysis:** The subscription model is gated by B2B account status with the developer, requiring an existing enterprise relationship to function.

<!-- section:sentiment -->
## 🔴 User Sentiment (Medium Confidence: 16 of 16 reviews analyzed) {#user-sentiment}
- **Overall Rating:** 5/5
- **Platform Split:** iOS 5.0/5 (2 ratings)
- **Overall Sentiment:** Frustrated
- **Note:** The 5/5 store rating reflects cumulative history, while the Frustrated sentiment reflects recent user reviews analyzed by our AI pipeline.

### Top Praises
- **Responsive technical support provides personalized assistance for complex aircraft performance and weight calculations**
- **Accurate performance modeling for high and hot operations provides critical decision support for flight crews**

### Top Complaints (Impact Areas)

- **Critical registration and submission errors prevent users from accessing the core interface after launch**

<!-- /section:sentiment -->
<!-- section:swot -->
## SWOT Analysis {#swot}

**Core Strengths:**
- Offline runway database removes connectivity dependency for critical flight calculations
- AFM-compliant modeling provides essential decision support for high and hot operations

**Growth Levers:**
- Localized performance forecasting (PCast) justifies the enterprise subscription cost
- Direct technical support provides a retention lever for complex flight departments


<!-- /section:swot -->
## Recent Changes (v4 → v5) {#recent-changes}

Critical registration and crash blockers have emerged, shifting the app's sentiment from neutral to negative and forcing a pivot in development priorities toward core stability.

**Overall trend**: Declining
**Compared at**: 2026-08-27

### High-impact changes
- **[Declined] Sentiment Shift to Negative** (sentiment)
- **[Declined] Outlook Trend Downgrade** (positioning)

### Medium-impact changes
- **[Added] Registration and Stability Weaknesses** (swot)
- **[Added] New Competitive Feature Gaps** (featureGaps)

<!-- section:whats-new -->
## What's New

- **Latest (v5.0.0, 3 months ago):** Introduced SID Comply for ground-based altitude restriction assessment and added departure recording of ground speed and ROC for simulator playback.
<!-- /section:whats-new -->

<!-- section:momentum -->
## App Momentum (Maintenance) {#momentum}

- Shipped SID compliance and simulator recording.
- Quiet 3 months, maintenance-mode cadence.

> **Cadence:** 1 total versions · 1 majors in last 6 months · 91 days since last update

<!-- /section:momentum -->

<!-- section:so-what -->
## The "So What?" (Strategic Takeaway) {#so-what}

EFB-Pro is a reference app.
With a 5/5 rating from 2 reviews, it draws more critical themes in recent reviews than its store average suggests.

<!-- speakable-start -->
> **Bottom Line:** The reliance on offline-first performance modeling provides a defensible niche, but the current registration and crash blockers prevent users from accessing the value they pay for. Resolving these stability issues would unlock the retention potential of the existing professional user base.
<!-- speakable-end -->

**Best for:** Professional turbine aircraft pilots and flight crews requiring FAA, EASA, and JAR compliant performance calculations.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [PIVOT] Rebuild registration flow because users are stuck in loops preventing dashboard access → unlock new-user conversion
<!-- /section:pm-actions -->

<!-- section:feature-gaps -->
### Feature Gaps vs Competitors


- Real-time safety alerts (available in No-ICE but absent here)
<!-- /section:feature-gaps -->

<!-- section:outlook -->
### Outlook: Declining

The aviation reference market is shifting toward modern, RAG-powered utilities that offer natural language querying and real-time synchronization. EFB-Pro's current maintenance-mode posture and technical instability leave it exposed to more agile rivals that offer a more reliable cockpit experience.

- 🔴 Critical registration and crash blockers prevent core access, which erodes the trust of professional flight departments.
- ⚪ The release cadence has slowed to maintenance-only, signaling that feature expansion is secondary to basic stability.
