<div class="paragraph"><p><span class="blue"><em>Version 1.1, September 2016</em></span></p></div>
<div class="paragraph"><p>Welcome as a user of <em>Subsurface</em>, advanced dive logging software with
extensive infrastructure to describe, organize, interpret and print scuba
and free dives. <em>Subsurface</em> offers many advantages over other similar
software solutions, including compatibility with Windows, Mac-OS/X, Linux (many
distributions), Android and iOS. In addition, <em>Subsurface</em> is
open-source software that allows downloading dive
information from most 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 an extension of <em>Subsurface</em> which
runs on Android smartphone and tablet devices and is a
tool for viewing or sharing dive information at dive sites where a larger
computer is not useful. <em>Subsurface-mobile</em> for Android also allows
the gathering of GPS locations where dives are performed
(Subsurface-mobile for iOS currently does not support GPS functionality).</p></div>
<div class="paragraph"><p><em>Subsurface-mobile</em> allows you to enter and save dive information
using a mobile device. Most users of <em>Subsurface-mobile</em> typically use the
mobile app as an extension to the laptop/desktop version of <em>Subsurface</em>.
This allows the storage of dive logs on the Internet sharing them
between the mobile and the desktop versions. But <em>Subsurface-mobile</em> can
be used independently of <em>Subsurface</em> and does not require the use of
cloud storage.
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.</p></div>
<div class="paragraph"><p><em>Subsurface-mobile</em> allows you to:</p></div>
<div class="ulist"><ul>
<li>
<p>
Download existing dive log information from the Internet.
</p>
</li>
<li>
<p>
View this information on a mobile device.
</p>
</li>
<li>
<p>
Edit many of the dive log data fields, e.g. divemaster, buddy,
  equipment or notes about a dive.
</p>
</li>
<li>
<p>
Manually create and add new dive records to your dive log.
</p>
</li>
<li>
<p>
Store the updated dive log in the <em>Subsurface</em> cloud storage.
</p>
</li>
<li>
<p>
Record, store and apply GPS positions of dives (Android only).
</p>
</li>
<li>
<p>
View 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.
What <em>Subsurface-mobile</em> does not support (at this time) is downloading
dive data directly from a dive computer. That still needs to be done using
<em>Subsurface</em> on a desktop or laptop computer. We are investigating ways
to support downloading from a subset of the supported dive computers on
Android devices, but this is not yet ready for testing.</p></div>

<h2 id="_using_em_subsurface_mobile_em_for_the_first_time">3. Using <em>Subsurface-mobile</em> for the first time</h2>
<div class="sectionbody">
<div class="paragraph"><p>Upon starting <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="paragraph"><p>Select whether <em>Subsurface-mobile</em> should access the Internet for dive log information.</p></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 striked-out cloud icon. The app will not access the <em>Subsurface</em>
cloud storage server
to obtain dive log information. This means that dive log information is manually
entered and stored on the mobile device only.</p></div>
</div>
<div class="sect2">
<h3 id="_using_cloud_storage">3.2. Using Cloud Storage</h3>
<div class="paragraph"><p>In order to use the <em>Subsurface</em> cloud storage, an account on the cloud
server is required. If you have already set up an account from the
<em>Subsurface</em> desktop application, enter the credentials here.</p></div>
<div class="paragraph"><p>You can also create a new account from your mobile device.</p></div>
<div class="sect3">
<h4 id="_using_the_desktop_version_of_em_subsurface_em">3.2.1. Using the desktop version of <em>Subsurface</em>:</h4>
<div class="paragraph"><p>Open the desktop version of <em>Subsurface</em> and
click <em>File   &#8594;  Preferences  &#8594; Network</em>, explained in detail in the
<a href="https://subsurface-divelog.org/documentation/subsurface-4-user-manual/#_create_a_cloud_storage_account">user
manual for the <em>Subsurface</em> desktop version</a>. Once the account has
been created and verified using the desktop version,
<em>Subsurface</em> desktop alows you to download dive information from dive computers and store this
on the cloud which can, in turn, be downloaded to <em>Subsurface-mobile</em>. <em>Subsurface-mobile</em>
attempts to download the existing dive log from the <em>Subsurface</em> cloud
server. Appropriate messages are shown onscreen. Finally a list of dives is shown.</p></div>
<div class="paragraph"><p>Once the dive
list has been downloaded from the Internet, <em>Subsurface-mobile</em> keeps a local
copy on the mobile device. This means that even if there is no Internet connection
at a dive site, you can still access the local copy and view and manipulate
dive information. If there is Internet connectivity, <em>Subsurface-mobile</em> accesses
the cloud-based dive log to verify that the local copy is still the
same as the Internet-stored copy. If not, the local copy and the copy on
the server are synchronised.</p></div>

<div class="sectionbody">
<div class="paragraph"><p>At the bottom of many Subsurface-mobile screens is a round button that provides for
several actions and which allows the selection of the main affirmative action
(see image above and image below).
On Android devices, use the Android Back
button for "cancel", "discard" or "back" actions. For example, when
editing dive information, tapping the action button saves the changes while the
Android back button can be used to cancel the edit without saving changes.</p></div>
<div class="paragraph"><p>On iOS devices, on screens where a "back" action is enabled, a back arrow
is shown in the top left corner of the screen.</p></div>

<div class="paragraph"><p>In order to have a consistent experience between iOS and Android,
<em>Subsurface-mobile</em> on Android does not use the traditional "hamburger"
menu button in the top left or right corner of the screen to open menus.
Instead, <em>Subsurface-mobile</em> uses a
different user interaction philosophy based on the Kirigami framework
developed by the Plasma developers. There are three ways to open the main menu:</p></div>
<div class="ulist"><ul>

dive list. While the dive list is loading from the cloud,
a message appears at the bottom of the screen, indicating that the cloud is
being accessed (see image on left, below). Once the list is loaded you can scroll up and down.
Tapping a dive on the list brings up a display of <em>Details View</em> for that dive (see image on right below).
This includes the dive profile as well as additional information and notes.</p></div>

tap the "plus" sign in the <em>Action Button</em>, or use the
main menu and tap <em>Manage dives  &#8594;  Add dive manually</em>. This opens  a screen that is
identical to the editing screen discussed above. When a dive is added manually, you
cannot directly add a dive profile from a dive computer. However, if you do not use a
dive computer, the duration, depth and several other bits of information about
the new dive can be entered. The <em>Action button</em> at the bottom of the screen

<h2 id="_dive_log_management">9. Dive log management</h2>
<div class="sectionbody">
<div class="paragraph"><p>A central  part of <em>Subsurface-mobile</em> is the ability to store the dive
log using the <em>Subsurface</em> cloud storage.
This provides security against loss or damage to the dive information contained in a local copy of
the dive log and allows the desktop version of <em>Subsurface</em> to
access changes made using the mobile device. This ability is accessed
through the main menu (by dragging the Action Button to the right, or
alternatively tappping the "Hamburger" icon at the bottom left of the screen).
Tap the option <em>Manage dives</em>, enabling a number of options:</p></div>
<div class="sect2">
<h3 id="_add_new_dive_manually">9.1. Add new dive manually</h3>
<div class="paragraph"><p>This is described above under the section dealing with the dive list.</p></div>

<h3 id="_sync_the_dive_log_with_the_em_subsurface_em_cloud_storage">9.2. Sync the dive log with the <em>Subsurface</em> cloud storage</h3>
<div class="paragraph"><p>You can upload the dives contained on the mobile device
to the <em>Subsurface</em> cloud storage by tapping the option <em>Manual sync with coud</em>.
This synchronizes the local changes to
the dive log with the cloud storage. It also downloads changes made on
another device or computer and stored in cloud storage.</p></div>
</div>
<div class="sect2">
<h3 id="_working_offline_or_online">9.3. Working offline or online</h3>
<div class="paragraph"><p>By default <em>Subsurface-mobile</em> runs offline and only syncs the dive list
with cloud storage when explicily told to do so (see above).
You can choose to always sync with the cloud servers after every
modification of the dive list. This is not recommended unless you are in
an area with fast and reliable internet connection, as otherwise
<em>Subsurface-mobile</em> might appear to hang between operations as it tries to
connect to the cloud server.</p></div>

<h2 id="_recording_dive_locations_using_gps_android_only">10. Recording dive locations using GPS (Android only).</h2>
<div class="sectionbody">
<div class="paragraph"><p>The fact that most smartphones have GPS facilities allows
<em>Subsurface-mobile</em> on Android to record
the locations of dives. You can take the smartphone on the dive boat
during a dive and locations will be automatically recorded at regular intervals.
These locations can then be applied to dives in the dive list. Here is how it&#8217;s done:</p></div>
<div class="sect2">
<h3 id="_setting_up_the_gps">10.1. Setting up the GPS</h3>
<div class="paragraph"><p>Open the main menu and tap <em>GPS  &#8594;  Preferences</em>. Now specify the way
in which GPS data need to be automatically collected (image on right,
below). You can specify that data are collected at regular intervals, e.g.
every 10 minutes, or at regular
distances, e.g. after the boat has moved more than 200m, or a combination of
both of the above approaches. Provide the appropriate information and
tap the <em>Save</em> action button. The program is now ready to collect GPS positions.</p></div>

<div class="paragraph"><p>Ensure that the GPS on the Android device has been activated. At the bottom
of the GPS submenu is a check box <em>Run location service</em> (image on left, above).
Check this box
and <em>Subsurface-mobile</em> starts to collect GPS locations automatically,
following the preferences specified as described above. After return from
the dive trip you can deactivate the collection of GPS data by de-activating
the same check box at the bottom of the main menu.</p></div>
</div>
<div class="sect2">
<h3 id="_storing_the_gps_data_on_the_em_subsurface_em_cloud">10.3. Storing the GPS data on the <em>Subsurface</em> cloud</h3>
<div class="paragraph"><p>Activate the main menu and select the <em>GPS</em> option that brings up the submenu of GPS-related actions
(image on left, above). Tap <em>Upload GPS data</em> that saves the GPS data
on the <em>Subsurface</em> cloud server. These GPS data are saved <strong>separately</strong>
from the other dive log data. All collected GPS data are kept on the
Android device, independent of whether they have been uploaded or not.</p></div>
</div>
<div class="sect2">
<h3 id="_downloading_gps_data_from_the_em_subsurface_em_cloud">10.4. Downloading GPS data from the <em>Subsurface</em> cloud</h3>

<div class="sect2">
<h3 id="_viewing_gps_data">10.5. Viewing GPS data</h3>
<div class="paragraph"><p>From the GPS submenu (image on left, above) select <em>Show GPS fixes</em>. This brings
up a list of GPS positions obtained using the location service (image
on left, below). Two actions are possible for each of the locations, enabled if
you tap the handle (the three horisontal stripes on the right, see image on left, below) and
then drags the specific item to the left (image on right, below). This exposes two
options. Tapping the dustbin deletes this particular GPS location. Tapping the
teardrop-shaped icon (actually a Google Maps pin) opens up Google Maps with a pin
indicating the exact map position of the GPS record being viewed. The two above
options can be hidden by drawing the GPS record to the right, again using the handle.</p></div>

<h3 id="_applying_gps_data_to_dives_in_the_dive_log">10.6. Applying GPS data to dives in the dive log</h3>
<div class="paragraph"><p>Assuming that all the dives have been entered into the dive log or have
been downloaded from the <em>Subsurface</em> cloud, you can apply the GPS positions to
these dives. GPS positions can therefore only be applied to dives in the dive list.
From the GPS subpanel, tap <em>GPS-tag dives</em>. The dive list contains the start
and end times of each dive. Now, <em>Subsurface-mobile</em> applies the first
GPS position that falls within the dive period of each dive. This results
in a GPS position for each dive that is saved as part of the dive log.</p></div>
