<div class="paragraph">
<p>Welcome as a user of <em>Subsurface</em> and <em>Subsurface-mobile</em>, advanced dive logging
software with extensive infrastructure to describe, organize, and interpret scuba
and free dives. <em>Subsurface</em> offers many advantages over other similar
software solutions, including compatibility with Windows, macOS, Linux (many
distributions), Android and iOS. In addition, <em>Subsurface</em> is
open-source software that allows downloading dive
information from many dive computers.</p>
</div>
<div class="sect1">
<h2 id="_introducing_subsurface_mobile">1. Introducing Subsurface-mobile</h2>
<div class="sectionbody">
<div class="paragraph">
<p><em>Subsurface-mobile</em> is a limited mobile version of <em>Subsurface</em>
aimed at Android and iOS smartphone and tablet devices, allowing viewing, entering, sharing, and storage of dive information at dive sites where a desktop
computer is not useful. While the desktop version of <em>Subsurface</em> shows much more detailed information
for each dive, the mobile version allows a more accessible dive log
on a dive trip, useful for proving dive experience to dive shops or to review
previous dives. <em>Subsurface-mobile</em> also allows
the gathering of GPS locations where dives are performed.</p>
</div>
<div class="paragraph">
<p>Users of <em>Subsurface-mobile</em> typically use the
mobile app as a companion to the laptop/desktop version of <em>Subsurface</em>,  sharing dive information
between the mobile and the desktop versions. However <em>Subsurface-mobile</em> can
also be used independently of the desktop version and does not require the use of
cloud storage.</p>
</div>
<div class="paragraph">
<p><em>Subsurface-mobile</em> allows:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Download and storage of dive log information using the <em>Subsurface</em> cloud.</p>
</li>
<li>
<p>Viewing this information on a mobile device.</p>
</li>
<li>
<p>Manually creating and adding new dive records to your dive log.</p>
</li>
<li>
<p>Download dive data directly from many dive computers.</p>
</li>
<li>
<p>Editing many of the dive log data fields, e.g. dive-master, buddy,
equipment or notes relating to a dive.</p>
</li>
<li>
<p>Recording, storing and applying GPS positions of dives.</p>
</li>
<li>
<p>Viewing the localities of recorded GPS positions and of dives
on a map.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>These items are discussed in greater detail in the following text.
<em>Subsurface-mobile</em> does not support download of dive data from all the
dive computers that the desktop/laptop version can. This limitation is
mainly caused by the inability of accessing some types of devices on the
two mobile platforms. On Android, a subset of
dive computers that use a FTDI USB interface or a Bluetooth / Bluetooth LE interface
are accessible by <em>Subsurface-mobile</em>. On iOS, only Bluetooth LE based
dive computers are supported.</p>

<h2 id="_installing_subsurface_mobile_on_your_mobile_device">2. Installing <em>Subsurface-mobile</em> on your mobile device</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Find <em>Subsurface-mobile</em> in the <em>Google Play Store</em> or the <em>iTunes Store</em>
and install it. Please note that both stores also contain the older <em>Subsurface</em> companion app (used only for tracking GPS positions) - make sure you actually install <em>Subsurface-mobile</em>.</p>

<h2 id="_using_subsurface_mobile_for_the_first_time">3. Using <em>Subsurface-mobile</em> for the first time</h2>
<div class="sectionbody">
<div class="paragraph">
<p>When you start <em>Subsurface-mobile</em> for the first time, a Subsurface
splash screen is shown while the program loads. On some devices this
may take several seconds. After loading, the <em>Cloud Credentials screen</em> appears
(see image below on left).</p>
</div>
<div class="imageblock text-center">
<div class="content">

</div>
</div>
<div class="sect2">
<h3 id="_when_not_using_cloud_storage">3.1. When NOT Using Cloud Storage</h3>
<div class="paragraph">
<p>Tap the "No cloud mode" button. The app will not access the <em>Subsurface</em>
cloud storage server
to obtain dive log information. This means that dive log information is
stored on the mobile device only. If no dives have been entered into the dive log
yet (the usual case), an empty dive log is created.</p>
</div>
</div>
<div class="sect2">
<h3 id="_using_cloud_storage">3.2. Using Cloud Storage</h3>
<div class="paragraph">
<p>The <em>Subsurface</em> developers provide a dedicated and
free Internet cloud storage account that can be used for
storing dive log information. This account can be created either from <em>Subsurface</em> on the desktop or from <em>Subsurface-mobile</em>
using a mobile device; you can
do full maintenance of a dive log from <em>Subsurface-mobile</em> alone. By using the same
credentials with <em>Subsurface-mobile</em> and <em>Subsurface</em> for desktop, the <em>Subsurface</em> cloud storage allows sharing of a dive
log between both (or even more than two) devices.</p>
</div>
<div class="paragraph">
<p>The dive data on the cloud are cached locally both on the mobile device as well as on the desktop - it is easy to create backups of the data (for example in XML format) on the desktop: both mobile device and desktop keep a local copy of the data so that the dive log is always accessible, even without Internet connection. The Subsurface team never accesses a user&#8217;s dive data without explicit permission to do so, the data are not used for any purpose other than providing them to the user who created them. There are no ads and no harvesting / analysis of the data stored in the Subsurface cloud storage.</p>
</div>
<div class="paragraph">
<p>1) Enter an e-mail address and a password in the fields indicated on the screen (see image above).
The e-mail address should be in lower case and the password should contain a combination of
letters from the alphabet (upper and lower case) and/or numbers.
Tap the "Sign-in or Register" button. If you have already set
up an account from the <em>Subsurface</em> desktop application, enter the same credentials here.
Once the dive
list has been downloaded from the cloud, <em>Subsurface-mobile</em> usually works only with the the local
copy on the mobile device. This avoids long delays or even failure of operations if there is a bad (or no) internet connection, a situation fairly common at many dive sites. Once registered, <em>Subsurface-mobile</em> remembers the cloud credentials and it is not necessary to provide these again when launching the program.</p>
</div>
<div class="paragraph">
<p>2) If this is a new cloud account, a PIN screen will open (see image on right, above). A PIN is e-mailed
to the email address entered in the previous step. Enter this PIN into the field indicated
and tap the <em>Register</em> button. The user
information is stored on the cloud server and access to the cloud is enabled. In this case
the dive list is initially empty. Start entering dives in the dive
log or download dive information from a supported dive computer.</p>

the names of the vendor and model of the dive computer. For instance, when using a Shearwater Petrel dive
computer, the vendor is <em>Shearwater</em> and the Dive computer name is <em>Petrel</em>(see image on the left, below).
<strong>Caveats:</strong> The download feature in smartphones supports only a limited number of dive computers. On
Android devices these are typically dive computers using an FTDI interface
using a USB OTG cable (but this is blocked on some Android devices by OS
settings). Android devices also support Bluetooth dive computers that
are supported in <em>Subsurface</em> on the desktop. Both Android and iOS devices allow direct
download of dive data from a handful of Bluetooth LE enabled dive
computers. Use the <em>Vendor name</em> and <em>Dive Computer</em> drop-downs to pick the correct
dive computer. When downloading from multiple different dive computers, shortcut
buttons appear below the drop-downs to easily switch between them. In the <a href="#S_Settings"><em>Settings</em></a> menu
you can remove these buttons, a useful feature for removing buttons of dive
computers that are not used any more. Achieve this by selecting the option
<em>Forget remembered dive computers</em> in the <a href="#S_Settings"><em>Settings</em></a> menu.
After all these caveats, let us proceed with download.</p>
</div>
<div class="paragraph">
<p><strong>For USB FTDI dive computers:</strong>
This feature is not supported on iOS and on most newer Android devices. It still works on some older
Android devices (typically Android 7 and older) and is kept enabled for this
reason. Note: USB cables "normally" used for uploading dives to a
desktop/laptop computer do NOT work; these
cables usually have a full-sized ("Type A") male USB plug
on one end which plugs into the USB port of a desktop/laptop computer. For downloads to a mobile device
one needs a USB OTG (USB On-The-Go) cable.</p>

receptacle of the mobile device. The
OTG cable usually has a full-size ("Type A") female receptacle at one end which
accommodates the full-sized male plug
of the USB cable "normally" used (see image below). This means that two cables are used to connect
the dive computer to the mobile device. <strong>Not all Android devices support OTG cables</strong>
and even on some devices that do support those cables in general, as mentioned above <em>Subsurface-mobile</em>
does usually not support cable based downloads, except on some older Android devices.</p></td>

<p><em>Subsurface</em> remembers the settings for dive computers that
have been successfully used (image on right, below). These appear
as buttons under a heading "<em>Previously used dive computers</em>".
Select the appropriate button. Having connected the USB dive computer to the
<em>Subsurface</em> computer and having selected the appropriate vendor and dive computer,
ensure that the Connection text box shows "FTDI".</p>
</div>
<div class="paragraph">
<p><strong>For BLUETOOTH/BTLE dive computers:</strong> The process for Bluetooth download is slightly different between Android and iOS.
In our testing we got the best results on iOS when the dive computer was
in Bluetooth mode before <em>Subsurface-mobile</em> is started. On most dive
computers this is done through a menu entry, others (like the Suunto
models) always respond to BTLE requests. However, on Android devices,
you should first establish a link between the
Bluetooth or Bluetooth LE dive computer and the mobile device using
Android utilities. See below for more details.</p>
</div>
<div class="paragraph">
<p>For Bluetooth-equipped dive computers and Android devices, establish a Bluetooth connection between the dive computer and the
mobile device. Use the tools on the mobile device to achieve pairing between the Bluetooth dice computer
and the mobile device. For many Android devices,
the Settings &#8594; Bluetooth tool of Android is probably appropriate.
<em>Subsurface-mobile</em> performs communication using both Bluetooth and Bluetooth-low-energy (BTLE).
The appropriate choice of Bluetooth communication is often made by the software and the user need not be concerned with this.
For dive computers with both Bluetooth and Bluetooth-low-energy (BTLE), a separate button is presented on the download
screen for each mode of communication, allowing a choice. Use the <em>Connection</em> value to distinguish between the
two options. In the image on the right, below, there are three buttons labeled "Shearwater Petrel 2". These represent two Shearwater Petrel dive computers, one of which can communicate in both Bluetooth as well as BTLE. The <em>Connection</em>
information indicates that the Petrel with no BTLE is selected.</p>
</div>
<div class="paragraph">
<p><strong>DOWNLOAD:</strong> With communication between dive computer and <em>Subsurface-mobile</em>
having been set up, tap the <em>Download</em> button. Be patient because the download can take a few minutes.
As a matter of fact, a complete first download from some dive computers can take 45 minutes or longer.
The downloaded dives appear in the bottom part of the screen,
