Diving Log for Android update available

Sunday, November 12th, 2017

A new update of Diving Log for Android is now available on Google Play. It contains the following new features and improvements:

  • Dive list: setting to display entry time, dive time & depth
  • PO2 & ascent rate profile
  • Statistics: setting for prior dive time & overall dive time format
  • Dropbox sync crash fixed for large logbook files
  • File size in logbook management and Dropbox sync dialog
  • Bug fix when creating logbook items with an apostrophe (‘)

You can now optionally show entry time, dive time & depth in the dive list (entry time was already visible in landscape and on tablets). In the dive profile view you can now view the PO2 & ascent/descent rate profiles. The statistics window got some more options to enter the prior dive time (dives not included in your logbook) and the overall dive time format (hours : minutes or days : hours : minutes):

I also finally found and fixed the bug which crashed the app when uploading large logbook files (> 20 – 30 MB) to Dropbox. And the sync function progress dialog shows the file size, so you can better estimate how long the upload will take.

Friday, August 26th, 2016

Today I’ve released an update of Diving Log for Android with a vastly improved statistics section. It was available for some time in the beta channel, but now it is released for everyone. You can view now most of the charts which are available in the desktop version and the statistic section is now also optimized for 7 and 10 inch tablets. The app is now also localized to Italian and the text selection overlay toolbar works better. Photos taken from within Diving Log are now also added to the Android Gallery app.

Logbook Filter and more

Saturday, April 21st, 2012

Today you can download a new beta version with some great new features:

  • New filter function for all output windows
  • vCard import for buddy details
  • UDDF 3.x import support
  • HeinrichsWeikamp Frog download support
  • Several bug fixes and other minor improvements

With the new filter window, you can create filters for any output window (logbook, details data, table editor, dive site map, statistics, printing and exports). Filters allow you to view, export or print only a subset of your logbook data, based on any criteria you want. For example, you can now view the statistics just for one year or just for your rebreather dives. You can export or print only dives where you’ve dived with just one particular buddy. Or you can view in the map window only dive sites, which are deeper than 30 m and with a rating of 5 stars (just an example).

To create a filter, click the new filter icon you’ll find now in most toolbars:

Logbook Filter

Statistics Filter

Export Filter

Then you will see on the right side of the current window the new filter toolbox, where you can add with “AND/OR” any number of criteria for every database field. As soon as you add, edit or delete filters, you can see the results live in the output window.

Filter Toolbox

Edit Filter

To edit a filter row, just double click it or hit the edit button in the toolbar. That way you can easily refine your filter until you get the data you want. You can save your filter to a file and reload it later on. You can also exchange filters between identical database tables, e.g. between statistics, logbook and table window or between dive site details and dive site map.

vCard Import: In the Buddy details you can import now vCard files, which can be created by most contact and email applications and webmail apps:

vCard Import

Click here to download the update beta setup file. This is an update from the current version 5.0.6. If you have an older version than 5.0.6, please update first to 5.0.6 and then install the beta update. Please let me know how you like the new filter function, if it works for you or if you see any crashes or bugs. The filter function integrates deeply into many parts of the application, so I want to make sure I’ve not broken any existing functionality.

 

SAC Rate Calculation

Sunday, April 3rd, 2011

Calculating the correct SAC rate for a dive sounds like a trivial and straightforward task, but if you want to do it right, you quickly get to some hurdles. SAC means “Surface Air Consumption” or for all German readers it’s the AMV = Atemminutenvolumen. The formula is indeed very simple:

MetricSAC = (TankPressureDiff * TanksizeLiter) / (Divetime * (AvgDepthMeter / 10 + 1))

ImperialSAC = ((TankPressureDiff / WorkingPressure) * TanksizeCuFt) / (Divetime * (AvgDepthMeter / 10 + 1))

So where is the problem, you think? Well, you have to consider:

  • Is there a dive profile? If so, I can calculate the average depth and dive time from the profile. If not, the average depth must be entered manually. Before calculating the SAC rate, I have to check if all required data is available
  • Metric or Imperial calculation?
  • Double tanks? If so, multiply tank size with 2
  • Now it’s getting complicated: Does the dive have multiple tanks? If not, we can calculate right away and that’s how it worked in the past. But now since Diving Log supports multiple tanks it’s getting a lot more difficult:

If a dive has multiple tanks, the only way to calculate a correct SAC rate for the whole dive is by calculating the separate rates for each tank and then the average. So now Diving Log will calculate the dive time and average depth for each tank by running through the dive profile. When completed, it will calculate based on these values the separate SAC rates for each tank and then the average rate for the whole dive. Look at this dive for example (all metric values):

Profile with multiple tanks

You can see the SAC rate for each tank in the tank window

So SAC rate calculation for dives with multiple tanks works only if a dive profile is available and when each tank is assigned to a part of the profile. Each dive can have up to 10 tanks. In a logbook with 1000 dives, each dive 10 tanks, Diving Log will have to calculate the SAC rate for 10000 tanks when creating the SAC rate chart below. Some dive computers record the profile with a 1 second interval, so you could imagine the amount of required calculations to create this chart:

SAC Chart

The improved SAC calculation will be available in the next beta.
