Mares, the well-known Italian manufacturer of diving equipment, has officially entered the smartwatch dive computer market with the launch of its Mares Dive App for the Apple Watch Ultra. The move represents a significant step forward in integrating Mares’ trusted dive-computer expertise with modern wearable technology, giving divers a new way to monitor and manage their dives directly from their wrists.
A New Era of Digital Diving
The Mares Dive App transforms the Apple Watch Ultra into a full-featured dive computer, bringing many of the functions divers would expect from a traditional device. It uses the Bühlmann ZH-L16C decompression algorithm and supports Nitrox gas mixes ranging from 21% to 50%.
Divers can log their dives digitally, track entry and exit points via GPS, and review detailed depth and time charts. The app also includes a built-in digital compass and integrates heart-rate monitoring for added physiological tracking during dives.
Firmware updates are delivered automatically through the Mares companion app, ensuring divers always have access to the latest features and improvements without manual updates.
Pricing and Availability
The Mares Dive App is available as a free download from the iOS App Store. A one-time in-app purchase unlocks the full dive-computer capabilities for Apple Watch Ultra users.
Competition and Innovation
Mares’ entry into this space follows similar offerings from other dive brands, but what sets this launch apart is its deep integration with Mares’ existing dive technology and its emphasis on accuracy, reliability, and user experience. The app applies Mares’ proven decompression logic in a format tailored to Apple’s hardware ecosystem.
At present, the depth limit remains consistent with the Apple Watch Ultra’s 40-metre restriction, which suits most recreational divers. Freediving functionality is not yet included, though Mares has indicated that future updates may expand the app’s capabilities.
Early Impressions
Initial feedback from divers suggests enthusiasm for Mares’ move into smartwatch-based diving. Early adopters have praised the app’s seamless syncing with dive logs and training platforms, while noting that Mares’ algorithm-based safety features add reassurance for those transitioning from dedicated dive computers.
The Verdict
The Mares Dive App for Apple Watch Ultra marks a pivotal point in the evolution of recreational diving technology. By combining the convenience of a smartwatch with the reliability of a traditional dive computer, Mares has effectively bridged the gap between innovation and practicality.
For divers who already own an Apple Watch Ultra, this app could make a capable and travel-friendly addition to their gear – though, as always, best practice is to carry a backup device and follow established safety protocols.
