Open Channel Flow Lite is a hydraulic engineering calculator for civil and water resource professionals, available on iOS.
The App DNA
What makes this app unique?
Engineers hire this tool for rapid, mobile-accessible Manning’s equation calculations, allowing for field-based flow analysis without desktop software.
For Civil and hydraulic engineers, water resource professionals, and engineering students.
What does it look like?
Key features
Calculates flow parameters for rectangular, trapezoidal, circular, and natural channels.
Saves up to 3 worksheets and 3 calculations for project reference.
Generates professional PDF reports of hydraulic calculations and visualizations.
How much does it cost?
Freemium model uses a hard limit on saved projects to incentivize conversion to the Pro version.
Velocity
Dormant developmentnew contentUX improvementsShow more...
The app has not received a single update in over 230 days, falling well outside the threshold for active development. The latest release provided a set of core hydraulic engineering features, but the lack of subsequent activity indicates the project is currently in a dormant state. There is no evidence of ongoing maintenance, feature expansion, or live operations.

Key takeaways for Open Channel Flow Lite
Where is it heading?
The hydraulic engineering utility market is consolidating around apps that offer broader structural analysis, leaving single-purpose calculators like this one exposed. The PM must increase project capacity to prevent power users from migrating to more versatile engineering suites.
- The app maintains a stable feature set focused on core hydraulic calculations, suggesting a maintenance-mode posture rather than aggressive expansion.
The SWOT
- Professional-grade Manning’s equation implementation provides immediate technical utility
- PDF export capabilities support professional reporting requirements
- Expansion into education-specific bundles could capture the student market
- Integration with cloud-based project management tools would increase professional stickiness

Since the last report: The report shows a strategic pivot toward specialized engineering competition and a refined roadmap focusing on worksheet capacity rather than cloud-sync.
Bottom line
Open Channel Flow Lite provides essential hydraulic utility, but the restrictive worksheet limit hampers professional adoption, so the PM should prioritize increasing the free-tier capacity to improve user retention.
