Logbook App FAQ

After opening the app all my records are gone!

There are two possible reasons. First it could be you just selected the wrong Logbook in settings. To check this, just go into the apps settings, scroll to Logbooks, and select the right one. The other reason could be in very rare cases the user interface does not connect to the database. In this case just kill the app (by swiping it up in app switcher) and restart it.

I am on water 24/7 for several days and noticed the app quits somehow each 24 hours?

It is really the case (I noticed this the first time with iOS12), that iOS seems to end (not kill, as there is no crashlog) all apps using location services each 24 hours. (e.g each day at 09:00). I can't avoid this behavior, but I will implement an alarm sound via push notification that will ring as soon as this happen, so you just have to reopen the app after this alarm sound and everything continues as expected. Please have some patience for the next update.

I had a trip in a different time zone, back home all times are wrong.

Without changing individual settings all new records are created in the time zone of you iOS device. So, if you create records in a different time zone the records will be shown based on your actual time zone. To avoid this, you can either set the real time zone in advance to your trip in the logbook individual settings (where you also can change logbook name, crew etc.). As this will create all new records in the selected time zone. Afterwards you have the possibility to scroll down to the very first record in your list and adjust the time zone for it. This will change the time zone also for all other record after this one. Keep in mind new records will still be created in the time zone you selected in the logbook settings. It is highly recommended you do a backup of your database before trying to fix wrong time zones in a valuable logbook.

How to backup, restore or copy the Logbook App database to another device?

If you would like to backup your Logbook database , just go to Tools, Export center and send the SQLite file via Email to yourself, save it to iCloud, or something similar. The database inlcudes all your logbooks, records, maneuver-, packing-, safety-lists.
Restore your backup
Just open the file (e.g. from your email) with logbook app. You will be asked if you really would like to replace the existing database. Be careful you will lose all data in the target app, and this cannot made undone.
Copy database from iPhone to iPad or vice versa
First do the export as described above, then copy the database directly via AirDrop to the other device, open it there with Logbook App.

What is the difference between Vmax Log and Vmax Track?

Difference between VMax Log and Track
In each record the SOG is saved, it represents the current speed at that time when the record was created. From all those values, the line Vmax Log is drawn.
In return Vmax Track is the speed calculated between two records, based on the distance divided by the time difference of those two records.

How are engine hours calculated?

You can chose in the settings tab between two different ways how to calculate the engine hours
Sum up
All entries of a day get summed up. So for example, you have one record with 2h at 8 a.m. and another one with 1.5h at 11 p.m. In the statics it would show up with 3.5h for this day.
This calculates the difference of the values. So again an example, at 10 a.m. the value is 1486.5 hours and at 6 p.m. it is 1489,5 this would show in the statistics as 3h for this day.

I would like to post my Logbook to Facebook, is this possible?

Can I use the App on multiple devices?
