The analysis now identifies a significant platform disparity, with Android serving as the primary engagement surface compared to the negligible iOS presence. **Overall trend**: Declining **Compared at**: 2026-09-01 ### High-impact changes - **[Shifted] Platform engagement disparity identified** (positioning) ### Medium-impact changes - **[Added] Technical strengths and specific threats** (swot) - **[Declined] Outlook trend downgrade** (positioning) ## What's New - **Latest (v4.0, 1 years ago):** Minor enhancement update. ## App Momentum (Zombie) {#momentum} - Ships no updates for 16 months. - Maintains 4.65 Android rating baseline. > **Cadence:** 2 total versions · 0 majors in last 6 months · 483 days since last update · 196 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Hydraulic System Calculator is a market-leading productivity app that is completely free. With a 4.65/5 rating from 658 reviews, it delivers strong user satisfaction. > **Bottom Line:** Restoring stability in the pump module would address the crashes driving negative sentiment, while persistent unit settings would remove the friction currently limiting daily utility for imperial-standard engineers. **Best for:** Engineers and technicians working with hydraulic cylinders, pumps, motors, and industrial piping systems. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Rebuild pump module stability because crashes are the top-reported frustration in the latest update → restore professional trust ### Outlook: Declining The engineering utility market is shifting toward cloud-integrated, cross-platform tools that sync data across desktop and mobile. Hydraulic System Calculator remains a static, siloed utility, and its lack of recent updates suggests it is no longer a priority for Trelleborg, which will accelerate user churn to more modern, maintained competitors. - 🔴 The 16-month development silence suggests the app has entered maintenance mode, which will eventually lead to compatibility issues with newer OS versions. - 🔴 Persistent crashes in the pump section following the latest update discourage professional use, causing engineers to seek more reliable, actively supported alternatives. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.65/5 | | Total Reviews | 658 | | Sentiment | Excited (75/100) | | Confidence | High | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Hydraulic System Calculator** (this app) | 4.65/5 | Excited | Trelleborg Sealing Solutions | | [Mitsu: AI Life Coach](https://marlvel.ai/apps/mitsu-ai-life-coach) | N/A/5 | N/A | C2 Insights | | [ChatGPT](https://marlvel.ai/apps/chatgpt) | 4.8/5 | n/a | OpenAI OpCo, LLC | | [HitWave](https://marlvel.ai/apps/ciendor-applications-hitwave) | 2.6/5 | Mixed | Ciendor Holdings Corp.
