Barometric+GPS vs Altimeter+ - **[Altimeter+](https://marlvel.ai/apps/sichtwerk-com-altimeter)** by Sichtwerk AG: This app is the direct market leader in the dedicated altimeter niche, commanding a massive user base that dwarfs this app's reach. - **Key differences:** - Maintains a singular focus on high-precision altitude tracking without the bloat of general navigation features. - Leverages a massive historical review volume to establish category authority and trust with outdoor enthusiasts. - Provides a specialized interface optimized for rapid altitude checks rather than complex map-based navigation. ### Contenders (Strong Challengers) - **[Compass ×](https://marlvel.ai/apps/com-mariposa-compassiphone)** by DOUBLE U s.r.o.: A dominant utility app that leverages massive scale to crowd out niche-specific altimeter tools in search results. - Utilizes a high-visibility brand presence to dominate the general navigation and orientation app store category. - Provides a simplified, high-contrast interface that appeals to users needing quick, reliable directional and altitude data. - **[Compass & Altimeter](https://marlvel.ai/apps/com-liouapp-compass)** by 明力 王: A high-volume competitor that bundles altitude tracking with essential compass functionality, capturing the broader utility-seeking audience. - Bundles essential orientation tools with altitude tracking to serve as a comprehensive outdoor utility suite. - Targets the casual user who prefers a single app for basic navigation and elevation data. ### Peers (What They Do Better) - **[Ski Tracks](https://marlvel.ai/apps/com-corecoders-skitracks)** by Fitness & Sports apps SRL: A specialized vertical app that uses altitude tracking specifically for performance analysis in winter sports. - Focuses exclusively on vertical drop and speed metrics, turning altitude data into a gamified performance score. - Optimized for cold-weather usage where battery efficiency and large, glove-friendly UI elements are critical. - **[Wikiloc - Trails of the World](https://marlvel.ai/apps/com-wikiloc-wikiloc)** by Wikiloc Outdoor SL: A community-driven platform that uses altitude data as a secondary metric within a massive global trail database. - Builds a network effect through user-generated trail content, making altitude data a component of the social experience. - Maintains high release velocity to keep the platform integrated with the latest mobile OS navigation capabilities. -

Last major update released 304 days ago. > **Cadence:** 6 total versions · 1 majors in last 6 months · 304 days since last update · 795 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Pro Altimeter - Barometric+GPS is a market-leading navigation app that is a paid app. With a 4.46/5 rating from 25.1K reviews, it delivers strong user satisfaction. > **Bottom Line:** Restoring launch stability is the immediate priority to defend the app's professional user base against entrenched rivals. Once stable, shipping historical data visualization will unlock the retention loop necessary to compete with high-volume navigation suites. **Best for:** Outdoor enthusiasts, hikers, and pilots requiring precise altitude measurements. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Rebuild launch sequence because launch crashes are the top complaint → restore daily active habit ### Feature Gaps vs Competitors - Historical data graphing (available in Gaia GPS but missing here) ### Outlook: Declining The navigation utility market is consolidating around apps that offer both high-precision data and social-sharing features. Pro Altimeter's current stability regressions and lack of feature velocity leave it exposed to rivals that offer better integration with modern mobile workflows, necessitating a pivot toward stability and data-visualization features to maintain its #41 chart slot. - 🔴 Launch crashes in the latest version prevent core utility access, which compounds the churn pressure from entrenched rivals like Altimeter+. - ⚪ The maintenance-mode release cadence leaves the app vulnerable to competitors that ship frequent feature updates to maintain store visibility. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.46/5 | | Total Reviews | 25.1K | | Sentiment | Excited (65/100) | | Confidence | Medium | | Pricing Model | Paid | | Platforms | iOS & Android | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Pro Altimeter - Barometric+GPS** (this app) | 4.46/5 | Excited | Craig Hunter | | [Wikiloc - Trails of the World](https://marlvel.ai/apps/com-wikiloc-wikiloc) | 4.8/5 | Mixed | Wikiloc Outdoor SL | | [Compass & Altimeter](https://marlvel.ai/apps/com-liouapp-compass) | 4.6/5 | n/a | 明力 王 | | [Radarbot: Speed Cameras | GPS](https://marlvel.ai/apps/com-iteration-mobile-radarbot-free-ww) | 4.6/5 | Thrilled | Iteration Mobile S.L | | [Gaia GPS: Mobile Trail Maps](https://marlvel.ai/apps/com-trailbehind-gaiagps-ng) | 4.8/5 | N/A | TrailBehind | | [Ski Tracks](https://marlvel.ai/apps/com-corecoders-skitracks) | 4.8/5 | N/A | Fitness & Sports apps SRL | ## Company Profile - **Developer:** Craig Hunter - **Website:** [https://hrtapps.com/proaltimeter](https://hrtapps.com/proaltimeter) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/pro-altimeter-barometric-gps/id926603602?uo=2) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.exatools.altimeter&hl=en&gl=us) - **Dev Site:** [Official Website](https://hrtapps.com/proaltimeter) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Wikiloc - Trails of the World*](https://marlvel.ai/apps/com-wikiloc-wikiloc) (Wikiloc Outdoor SL) · 4.8/5 Rating - [*Compass & Altimeter*](https://marlvel.ai/apps/com-liouapp-compass) (明力 王) · 4.6/5 Rating - [*Radarbot: Speed Cameras | GPS*](https://marlvel.ai/apps/com-iteration-mobile-radarbot-free-ww) (Iteration Mobile S.L) · 4.6/5 Rating | Excellent Sentiment - [*Gaia GPS: Mobile Trail Maps*](https://marlvel.ai/apps/com-trailbehind-gaiagps-ng) (TrailBehind) · 4.8/5 Rating - [*Ski Tracks*](https://marlvel.ai/apps/com-corecoders-skitracks) (Fitness & Sports apps SRL) · 4.8/5 Rating - [*Altimeter+*](https://marlvel.ai/apps/sichtwerk-com-altimeter) (Sichtwerk AG) · 4.5/5 Rating - [*what3words: Navigation & Maps*](https://marlvel.ai/apps/com-what3words-ios-what3words) (what3words Ltd.) · 4.8/5 Rating - [*Compass ×*](https://marlvel.ai/apps/com-mariposa-compassiphone) (DOUBLE U s.r.o.) · 4.7/5 Rating - [*Google Maps*](https://marlvel.ai/apps/google-maps) (Google) · 4.0/5 Rating - [*전국 시외버스 승차권 통합 예매(버스타고)*](https://marlvel.ai/apps/com-ebcard-bustago) (EZL Corp.) · 1.6/5 Rating ## Frequently Asked Questions {#faq} ### Is Pro Altimeter accurate for professional use?
