Subsurface-mobile is a free open source iOS divelog application that allows you to track your dives on your iPhone or iPad. You can scroll through your dive lists and view the details of individual dives. You can change those details on your mobile device and manually add new dives to your dive list.

Used together with Subsurface, a free open source dive log application available on Windows, Mac and Linux, Subsurface-mobile allows you to access the same dive log on your computer, tablet, and phone. Simply create a Cloud Storage account, store your dive log in the cloud and then enter the same credentials in Subsurface-mobile. Usage of cloud storage is optional, but greatly increases the usefulness of this application.

Subsurface-mobile on iOS cannot download dive information directly from a dive computer. For this you need Subsurface on your computer.

On iOS, Subsurface-mobile does NOT replace the Subsurface companion app, as Subsurface-mobile cannot track your GPS location at this time.

What's New

Version 2.0.1

Subsurface-mobile can now download dive data directly from a number of Bluetooth LE enabled dive computers.
Version 2.0 brings a major overhaul of the UI which now looks much more modern and makes it easier to edit dives on the go.
This new version also brings the ability to record GPS locations for dive sites - something that previously required the Subsurface Companion app on iOS.

Customer Reviews

Save support broken


This review is for this version only. Cloud saving is broken, preventing the entering of new dives or modifying existing. It is also far too easy for an inadvertent swipe to lose all notes in progress prior to "saving". The note field does not scroll, preventing the creation/editing of longer notes

All my dive buddies can finally get it


I have been singing the praises of this great app since I started testing it. I love the open source desktop app and this was the only thing that kept it from being great.

This app lets me view and edit my saved dives via the subsurface cloud. Nothing but wonderful.

Impressive Profile Charts


While not as flashy in terms of equipment tracking as other options, I really like the data-rich charts.

Easily imported my log data from another popular logging app after exporting as XML.

Not sure I'll give up that flashy closed source app, but will definitely play with this one too.

Seamless integration across Mac, Windows, Linux, Android, and iOS.

Nicely done!
