Sychronize Swisslog with a mobile Log?

[DL1MKP]

When working as DL1MKP/p I’m using <HAM2K portable logger> on my iPhone. Therefore I have two completely independent 
logs now. I’m looking for an integration of a mobile log and swisslog, where swisslog is my master-logbook.

<HAM2K portable logger> is offering an ADIF-File import - but that’s the wrong way round for me. I’m looking for a mobile 
solution on my iPhone, that is able to export an ADIR-File to swisslog. The goal is to keep just one log for all QSOs. 
I think, that is a simple task, if you are using a mobile log, providing the necessary features.

Does anyone know, how to make that happen?
Is there an iPhone-App available doing that? I didn’t find one.
