Tank Volume Calculator is a utility app for calculating filled and half-filled volumes of 15 different tank types on iOS and Android.
The App DNA
What makes this app unique?
It removes the cognitive cost of manual geometric calculations for industrial and residential fluid storage estimation.
For Professionals and DIY users requiring volume estimations for industrial or residential tank storage.
What does it look like?
Key features
Calculates volume for 15 distinct tank geometries including horizontal cylinders, cones, and trapezoids.
Facilitates volume output in liters, imperial gallons, US gallons, barrels, and cubic units.
How much does it cost?
Monetization splits between ad-supported volume on Android and a direct $3.99 purchase gate on iOS.
Velocity
Maintenance developmentperformanceUX improvementsShow more...
The app exhibits a maintenance-level development cadence, with only two releases identified over a period of approximately 20 months. The latest release occurred in January 2026, following a significant gap since the previous update in June 2024. Development is limited to minor optimizations and calculation improvements, with no evidence of new feature sets or live operations. The current release frequency is well below the threshold for active development.

Key takeaways for Tank Volume Calculator
Where is it heading?
The utility-calculator market is consolidating around tools that offer granular, industry-specific precision. Tank Volume Calculator remains exposed due to its lack of imperial-unit support, which will likely drive professional users toward more specialized fluid-mechanics rivals in the coming quarters.
- The lack of inch-based measurements limits the professional user base, which compounds the churn pressure from ad-heavy monetization on Android.
- Maintenance-mode release cadence ensures stability but leaves the app exposed to rivals with more frequent, feature-rich updates.
The SWOT
- 15-geometry support library functions as a B2B distribution barrier into industrial inventory estimation
- Localized inch-based measurement support would address the #1 recurring user request

Since the last report: The product strategy shifted from general feature expansion to addressing professional-grade precision requirements, specifically the demand for imperial unit support. This pivot follows a decline in sentiment score from 85 to 65, driven by emerging complaints regarding calculation accuracy and ad-interruption.
Bottom line
Tank Volume Calculator maintains a solid reputation among mechanical professionals for its core calculation speed, but monetization via ads and a lack of granular unit support are significant friction points. Addressing these unit limitations would improve the utility for the core professional user segment.
