Open Channel Flow Pro is a hydraulic engineering calculator for civil engineers and students on iOS.
The App DNA
What makes this app unique?
Users hire the app to automate complex hydraulic math, but the current execution fails to provide the reliability required for professional engineering tasks.
For Civil engineers, students, and technical professionals working with open channel hydraulics.
What does it look like?
Key features
Computes wetted perimeter, area, and hydraulic radius.
Maps discharge versus water depth relationships.
Allows input for non-uniform channel geometries.
How much does it cost?
Paid model anchored at $2.99, targeting professionals and students requiring specialized hydraulic engineering tools.
Velocity
Dormant developmentnew contentUX improvementsShow more...
The app has not received a release in over 8 months, placing it firmly in the zombie category. The most recent update provided significant feature additions, but the lack of subsequent activity indicates development has ceased. There is no evidence of ongoing maintenance or live operations support.

Competitive landscape for Open Channel Flow Pro
How's the Productivity market?
The app maintains a 1.67-star rating across three reviews, signaling a lack of market traction. The absence of a free-to-try model at the $2.99 price point prevents the conversion of students who currently favor free, multi-window alternatives.

The Analyst's Read
Key takeaways for Open Channel Flow Pro
Where is it heading?
The engineering calculator market is consolidating around multi-window, interactive tools that prioritize workflow efficiency. Open Channel Flow Pro remains in maintenance mode, which will lead to further rating erosion and total loss of the student demographic to free, modern alternatives.
- The 1.67-star rating indicates a failure to meet professional expectations, which will accelerate churn to multi-window competitors.
- Lack of recent feature updates leaves the app in maintenance mode, allowing rivals to capture the professional engineering segment.
The SWOT
- Rating curve generation provides specialized utility for hydraulic modeling.
- Adding a multi-screen workspace could capture users migrating from linear calculators.
Next best moves
Ship stability patch because the 1.67-star rating prevents professional adoption → restore baseline trust.

Since the last report: The competitive assessment expanded to include specific multi-window tool threats, and the PM strategy shifted to prioritize a trial model to overcome acquisition barriers.
Bottom line
Open Channel Flow Pro fails to meet professional standards due to stability issues and a restrictive pricing model, so the PM must prioritize stability fixes to prevent total churn and enable a trial model to attract new users.
