Dive Nitrox
By Jim Corbo
Dive Nitrox is a free SCUBA utility for calculating gas limits (EAD, MOD, Best Mix) on iOS.
The App DNA
What makes this app unique?
Divers use the app to quickly determine safe oxygen exposure limits for enriched air nitrox dives without manual table lookups.
For SCUBA divers who use enriched air nitrox and require a portable tool for calculating gas limits and depths.
What does it look like?
Key features
Calculates Equivalent Air Depth for enriched air nitrox mixtures based on user-input depth and oxygen percentage.
Determines Maximum Operating Depth for a chosen nitrox mix and partial pressure of oxygen limit.
Calculates the optimal enriched air nitrox percentage for a specific target depth and partial pressure of oxygen.
How much does it cost?
The app is distributed as a free utility with no observable monetization or in-app purchase gates.
Velocity
Dormant developmentopaqueShow more...
Dive Nitrox has been inactive for 4,061 days, far exceeding the threshold for a zombie classification. There is no evidence of ongoing development, feature updates, or maintenance. The app's history consists of a single release that provided no new features, indicating a complete cessation of development activity.

Key takeaways for Dive Nitrox
Where is it heading?
The market for dive utilities is consolidating around apps that offer wearable integration and cloud-sync. Dive Nitrox remains in a static state, meaning it will continue to lose relevance as users migrate to platforms that support modern iOS hardware and safety-critical data requirements.
- The 11-year development hiatus creates a significant trust gap for users, which will accelerate churn toward modern, actively maintained dive-planning alternatives.
The SWOT
- Simple slider-based UI provides immediate access to core gas-limit calculations without menu-diving
- Open-sourcing the codebase could allow the community to maintain the utility
Next best moves
Open-source the codebase because the app has been in maintenance-mode for over a decade → preserve utility for niche users

Read the full takeSince the last report: The analysis shifted from a purely negative assessment of a zombie project to a more detailed evaluation of its potential as a static, open-source utility.
Bottom line
Dive Nitrox provides a functional, no-cost utility for basic gas calculations, but its decade-long abandonment makes it a liability for safety-critical planning, so the developer should open-source the project or sunset the listing.
