There is a mijn.loondossier app for iOS (iPhone, iPad), and Android.
• The app is especially useful for employees, who can always view their pay slips, among other things.
• The app shows almost everything that you can also see via mijn.loondossier.nl, but you do not need a pc.
• You can install the app for free, as you are used to with your smartphone or tablet.
