It holds a 2/5 rating from 6 reviews. > **Bottom Line:** Crew Rest Calculator provides a necessary utility for flight crews, but the latest update broke core functionality, so the developer must prioritize stability fixes to prevent total user churn. **Best for:** Long-haul flight crews requiring precise, automated rest period calculations during flight rotations. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship stability patch for input freezing because it is the top-reported bug → restore core utility ### Outlook: Declining The app is currently in a declining state due to critical technical failures following a major interface update. Without an immediate stability patch, the user base will likely abandon the tool for manual alternatives, effectively ending its viability as a flight-crew utility. - 🔴 UI regressions in the latest update prevent calculation output, which erodes the daily active habit and drives negative sentiment. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2/5 | | Total Reviews | 6 | | Sentiment | Frustrated (25/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Crew Rest Calculator** (this app) | 2/5 | Frustrated | WILL3D | | [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 | | [1st Central Connect](https://marlvel.ai/apps/1st-central-connect) | 3.0/5 | N/A | Cambridge Mobile Telematics Inc. | | [2 one day trips Tokyo suburbs](https://marlvel.ai/apps/2-one-day-trips-tokyo-suburbs) | N/A/5 | N/A | mlet co.,ltd | | [360 Central Park AR NYC Map](https://marlvel.ai/apps/com-vues-360centralpark) | N/A/5 | N/A | Vadym Ustymenko | ## Company Profile - **Developer:** WILL3D ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/crew-rest-calculator/id1662243748?uo=4) - **Sources:** 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 - [*1st Central Connect*](https://marlvel.ai/apps/1st-central-connect) (Cambridge Mobile Telematics Inc.) · 3.0/5 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 - [*360 LA Los Angeles AR Map*](https://marlvel.ai/apps/360-la-los-angeles-ar-map) (Vadym Ustymenko) · 5.0/5 Rating - [*360 NYC: New York City AR Map*](https://marlvel.ai/apps/com-vues-360nyc) (Vadym Ustymenko) · 4.0/5 Rating - [*360 Tampa Bay AR Map*](https://marlvel.ai/apps/360-tampa-bay-ar-map) (Vadym Ustymenko) · 5.0/5 Rating - [*3HStay.com: Booking Hotels*](https://marlvel.ai/apps/3hstay-com-booking-hotels) (ABS Software International Sdn.
