Scuba Tank Capacity
Scuba Tank Capacity is a precision gas calculator for technical and recreational divers, providing Z-factor corrected volume estimates on iOS.
The App DNA
What makes this app unique?
Divers use the tool to remove the 5-10% error margin inherent in ideal gas calculations, ensuring safety during high-pressure technical dives.
For Recreational and technical scuba divers, as well as dive shop staff, who require precise gas volume planning tools.
What does it look like?
Key features
Calculates actual gas content by adjusting for non-ideal gas behavior at pressures exceeding 200 bar.
Performs all gas and tank calculations without requiring an active internet connection.
How much does it cost?
The app operates as a free utility with no monetization gates, positioning itself as a community resource for technical and recreational divers.
Velocity
Maintenance developmentperformanceShow more...
The app follows a maintenance-focused development cycle, shipping only two releases over the last six months. With a cadence of approximately one release every three months, development is primarily reactive to functional bugs rather than feature expansion. The latest release specifically corrected a gas volume calculation error for dual tank configurations. No new features or content updates have been introduced, indicating a stable, utility-focused product lifecycle.

Key takeaways for Scuba Tank Capacity
Where is it heading?
The technical diving utility market remains stable, favoring tools that provide verifiable accuracy over those that prioritize frequent feature updates. Scuba Tank Capacity is well-positioned as a precision-first utility, but the lack of a clear monetization or growth roadmap leaves it exposed to potential abandonment if developer interest shifts.
- The maintenance-only release cadence (two updates in six months) signals a stable utility tool rather than a growth-focused product.
The SWOT
- Z-factor correction provides technical accuracy beyond standard recreational calculators
- Cloud-sync for custom tank profiles would increase switching costs for technical divers
Next best moves
Ship cloud-sync for custom tank profiles because it increases switching costs for technical divers → improve long-term retention
The counter-intuitive read
The lack of monetization is a competitive advantage in the technical diving niche…
Read the full takeSince the last report: The app's competitive outlook has shifted from viewing its lack of monetization as a defensive barrier to identifying it as a vulnerability that risks project abandonment. The technical value proposition is now more precisely defined by the 5-10% variance from ideal gas estimates.
Bottom line
Scuba Tank Capacity serves the technical diving niche by prioritizing calculation precision over monetization, but the current maintenance-only cadence risks losing the trust of power users who require consistent updates for modern device compatibility.
