Export & Import ADIF?

Using QRZ’s logbook adif file as an import to the app was difficult. First, I had to change the file to a txt document type and then copy & paste to the app’s adif section. Second, I had to hand correct multiple mistakes. Even though my adif file was in a folder on iCloud, the app did not recognize it.

Once all my files were corrected, I had hoped to export my new RUMlog as an adif file. This option is not available as stated in the Apple store description.

Pesky rate me

I've been using the app less than five minutes and it's prompted me for a rating three times. FFS, please give me a chance to use it!

In those five minutes I see some useful functionality but it's just a bit off. For example there is an option to import from Dropbox but this doesn't actually import an ADIF - that's further down on the settings. I think it's meant for the database? maybe use the file extension and make it generic?

After importing I hoped to see QSOs on the map but it's only showing my point and the region lines. It's not zoomable.

Will spend more time playing with it.

Developer Response ,

According the documentation from Apple you may be asked for a review three times a year only as maximum. It seems, you have got the jackpot in 5 minutes. :-)

Not user-friendly

This is a very difficult Logbook program in terms of being user-friendly.

More testing is needed for the iPhone platform.

More ease in importing and exporting adi files., ie.,setting-up new files, creating new logs, and better documentation, case in point, locator characters must be in all caps when editing and saving a record for updating in the RUMlogNG app.

Backward compatibility with other logging software should be considered.
