What hidden app?

The main thing is to keep your main phone clean, because one day she will spring it on you to have access to your phone for whatever reason. However, having two phones would also raise questions (she will see the second phone eventually).

I don't believe there is a 100% water tight method. Some traces will always be left, it's just a matter of whether your partner will be curious or motivated enough to look.
