GasCalc Pro is a utility app for engineers and technicians providing gas flow, pipe diameter, and pressure calculations on iOS.
The App DNA
What makes this app unique?
Users hire this app to perform complex industrial calculations on-site, replacing manual reference tables with a digital, multilingual toolset.
For Engineers, technicians, and professionals requiring on-site gas flow and system pressure calculations.
Key features
Calculates flow rate and velocity for gas systems
Determines optimal pipe sizing for system design
Computes safety-relevant system pressures for engineering compliance
Estimates operating costs and compares fuel efficiency scenarios
Interface localization in German, English, Spanish, French, Italian, and Turkish
How much does it cost?
The app is currently distributed as a free utility with no visible monetization gates or subscription tiers.
Velocity
Dormant developmentopaqueShow more...
The app has not received a single update in the last 10 months, placing it firmly in the zombie category. There is no evidence of active development, feature releases, or maintenance patches. Given the lack of activity since July 2025, the development momentum is non-existent.

Competitive landscape for GasCalc Pro
How's the Business market?
GasCalc Pro enters the Business category as a free utility, lacking the rating volume of established 2014-era competitors like Material Weight Calculator.
Read the market outlookThe rivals identified
By Michael David
This app competes directly by targeting the same industrial professional demographic that requires quick, on-site material calculations for engineering projects.
- Offers a dedicated keyboard dismissal feature that streamlines data entry for busy field technicians.
- Focuses exclusively on material weight, providing a more specialized toolset than our broader gas-focused calculator.
Unlock the head-to-head verdict: where this rival wins, and where it loses.

Key takeaways for GasCalc Pro
Where is it heading?
The industrial utility market is consolidating around tools with proven reliability and field-optimized interfaces. GasCalc Pro remains exposed due to its lack of market traction, so the PM must pivot to active user acquisition to avoid long-term obsolescence.
- The app remains in a post-launch state with no feature updates, signaling a lack of active development or market testing.
The SWOT
- Multilingual support functions as a B2B distribution barrier into international engineering markets
- Broad calculation module suite covers multiple professional workflows
- Integration of offline-first field diagnostics could capture users from competitors lacking mobile-ready interfaces
