The Ocean at Your Wrist
The era of paper dive logs is over. With the arrival of Mares App on Apple Watch Ultra, divers now have a connected tool that transforms their watch into a true underwater brain. Developed by the Italian giant Mares, this application combines technical precision with ease of use, allowing divers to log their dives in seconds, share their marine encounters, and manage their equipment with astonishing intuitiveness. In a market saturated with generalist apps, the Mares App stands out with its seamless integration with the brand’s leading dive computers and its zero friction approach for the demanding diver.

Optimized for the Apple Watch Ultra
Say goodbye to tedious post-dive entries! Mares App automatically syncs your data via Bluetooth from compatible Mares computers (Smart, Sirius, Puck Pro Plus, Quad 2, etc.), capturing depth, decompression time, temperature, and dive profile with exceptional reliability. The app now supports freediving, rebreather diving (SCR/CCR), and technical diving, thanks to certified algorithms. Its clean interface, optimized for the Apple Watch Ultra, displays no-deco time, ascent rate, and regulator autonomy in real time. A QR code function allows you to instantly share your dive log with your crew, while the interactive world map immortalizes each marine encounter—even unreferenced species can now be added manually, addressing a recurring user request.
Electronic Precision: The Apple-Mares Alliance at the Abyssal Depths
Behind its sleek design lies cutting-edge technology. The app leverages the Apple Watch Ultra’s depth and temperature sensors up to 40 meters, with specific calibration to avoid measurement errors. Technical divers will appreciate the integrated decompression tables and customizable alerts when critical thresholds are exceeded. The digital gear management is a major asset: each buoyancy compensator, each regulator can be referenced with a photo, invoice, and maintenance date, while the automatic reminder system prevents any workshop lapses. The latest update (v0.9.180) even integrates the Sirius L, allowing maximum values to be added directly in freediving, and fixes display bugs in dark mode.

Available for free on the App Store
Mares App is available for free on the App Store, with premium features accessible by subscription. Whether you are a beginner or a seasoned instructor, this app will quickly become indispensable during your dives. Test its seamless integration with your Mares dive computer or Apple Watch Ultra now, and enjoy regular updates that transform every user feedback into concrete improvements. Mares App is not just a simple logbook: it is a connected community, ready to explore the depths with you.
Mares: 75 Years of Innovation
Behind this application lies a legacy of expertise. Founded in 1949 in Italy, Mares embodies European excellence in underwater equipment, with innovations like the first diaphragm regulator and the Sub700 flash. Its transition to digital is not a marketing whim but a pioneering logic: from the integration of intelligent diving sensors to the creation of global databases of submerged sites, the company anticipates divers’ needs before they even express them. With the Mares App, it confirms its commitment to making diving safer, more social, and resolutely modern—without ever sacrificing the technical rigor that built its legend.
