This shift reflects a focus on retaining student pilots by addressing core reliability concerns. **Overall trend**: Stable **Compared at**: 2026-08-18 ### High-impact changes - **[Added] Weather Decoding Audit** (pmActionItems) ### Medium-impact changes - **[Shifted] Threat Landscape Pivot** (swot) - **[Shifted] Student Pilot Inclusion** (audience) ## App Momentum (Maintenance) {#momentum} - Released initial version 85 days ago. - Maintains maintenance-only release cadence. > **Cadence:** 1 total versions · 0 majors in last 6 months · 85 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Aviation Calculator AvCalc is an utilities app that is completely free. It holds a 5/5 rating from 3 reviews. > **Bottom Line:** Maintaining the current feature set without regular updates risks obsolescence in a category where weather and navigation data require constant validation. Shifting to a regular update cadence would signal reliability to student pilots, securing the app's position as a trusted reference tool. **Best for:** Pilots, student pilots, and flight planners requiring quick, cockpit-accessible aviation math and weather decoding. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship cloud-sync for saved calculations because local-only storage limits utility across multiple devices → increase user retention ### Outlook: Stable Aviation Calculator AvCalc occupies a stable but vulnerable position in the Utilities category. The lack of recent updates suggests the developer is not actively competing for market share, which may lead to user attrition as rivals introduce more frequent weather-data refreshes. - ⚪ The 85-day update silence indicates a maintenance-only posture, which limits the ability to respond to changing aviation data standards. - 🟢 The 5.0-star rating confirms the core calculation suite meets user needs for speed and repeatability during flight preparation. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 3 | | Sentiment | Thrilled (90/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Aviation Calculator AvCalc** (this app) | 5/5 | Thrilled | Fifteen Jugglers Software UG | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.4/5 | Mixed | Fuxin Technology | | [Potatso](https://marlvel.ai/apps/potatso) | 4.4/5 | n/a | Potatso Lab LTD | ## Company Profile - **Developer:** Fifteen Jugglers Software UG ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/aviation-calculator-avcalc/id6767033258?uo=4) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.4/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Aviation Calculator AvCalc suitable for student pilots?
