Hydraulic System Calculator is a technical utility for engineers to compute hydraulic cylinder, pump, and piping parameters on iOS and Android.
The App DNA
What makes this app unique?
The tool removes the need for manual fluid power math in field environments, displacing paper-based reference charts with dynamic, ISO-compliant results.
For Engineers and technicians working with hydraulic cylinders, pumps, motors, and industrial piping systems.
What does it look like?
Key features
Calculates areas, volumes, forces, and velocity for cylinders, reinforcing Trelleborg's authority in sealing solutions.
Computes flow rate and power, positioning the developer as a technical partner in B2B procurement cycles.
Calculates pressure drop and Reynolds number, increasing switching costs for engineers requiring complex system design.
How much does it cost?
The app functions as a free technical resource to support the developer's core business of selling engineered polymer solutions.
Velocity
Dormant developmentopaqueShow more...
Development has ceased, with no new feature builds or updates released in over 480 days. The app currently sits in a zombie state, as the last update occurred well beyond the 12-month threshold for active maintenance. There is no evidence of ongoing support or operational activity.

Key takeaways for Hydraulic System Calculator
Where is it heading?
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.
The SWOT
- ISO 3320, 3321, and 4393 compliance provides technical credibility for industrial design
- Interactive cylinder imagery reduces cognitive load for complex component setup
- Adding specialized modules for hydraulic jacks and presses would capture the most frequently requested functionality
Next best moves
Rebuild pump module stability because crashes are the top-reported frustration in the latest update → restore professional trust
+ 1 more prioritized moveThe counter-intuitive read
The app's primary value is not the calculation math…
Read the full takeSince the last report: Market outlook has shifted from mixed to declining as the lack of updates over 483 days is now explicitly linked to the risk of OS incompatibility and user churn. The analysis now identifies a significant platform disparity, with Android serving as the primary engagement surface compared to the negligible iOS presence.
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.
