Hydraulic ToolKit
By Wade Trim
Hydraulic ToolKit is a free civil engineering utility for iOS and Android that provides seven standard hydraulic formulas and unit conversion for field calculations.
The App DNA
What makes this app unique?
The app removes the friction of returning to an office workstation to verify basic flow or sizing parameters during site observations.
For Civil engineers and students requiring portable hydraulic calculation checks.
What does it look like?
Key features
Calculates seven formulas including Rational Formula and Circular Orifice Flow.
Provides hydraulic coefficients for on-site verification.
How much does it cost?
The app serves as a free utility to support professional workflows and brand outreach.

Maintenance developmentUX improvementsnew contentShow more...
The app has been inactive for approximately 4.5 months, with the latest release occurring 140 days ago. Development is currently in a maintenance state, as no updates have been deployed to either platform since the spring of 2026. The last significant activity focused on UX improvements and the addition of new calculation formulas, but the lack of subsequent releases suggests a period of stagnation.

The Analyst's Read
Key takeaways for Hydraulic ToolKit
Where is it heading?
The market for specialized engineering utilities is consolidating around tools that offer broader formula libraries or integrated project logging. Hydraulic ToolKit remains a stable brand asset for Wade Trim, but its current maintenance-only cadence leaves it exposed to more agile, feature-rich competitors.
- The 140-day update gap indicates a maintenance-only posture, which limits the app's ability to capture new professional engineering segments.
The SWOT
- Portable field reference tool enables on-site hydraulic verification
- Seven-formula library covers standard civil engineering use cases
- Metric and imperial unit toggles support international project requirements
- Integration of offline-first project logs would capture field data currently recorded in paper notebooks
- Expansion of the formula library to include specialized stormwater management calculations
Next best moves
Audit OS compatibility because the app has not shipped a feature update in 140 days → maintain platform stability
The counter-intuitive read
The app's lack of complex features is its primary strength…
Read the full takeBottom line
Maintaining the current formula library provides a stable brand touchpoint for Wade Trim, but the lack of active development risks the app becoming a legacy utility.
