About Qt License in Mobile

[NullNull]

Hello,
We are a software company based in Turkey, and we currently have Android/iOS applications that are already in service. These applications are entirely commercial. We are considering rewriting our applications using Qt, but we have concerns regarding licensing. If we develop our commercial applications with Qt and publish them on Android/iOS platforms, will we need to pay any fees?

I personally use Qt for free under open-source conditions. However, the following two links should provide all the information you need for licensing in Qt:

Qt Group
Qt Docs

I still recommend contacting the company directly and asking for advice.

@NullNull At least, you need to link Qt LGPL libs dynamically and be aware some of Qt libs are not LGPL.

As Saviz said, better to contact Qt directly.

My research confirms that if we link libraries dynamically, there doesn't seem to be any issue. For Android, Qt's libraries are linked dynamically, and .so files serve this purpose. I was wondering how this works on the iOS side. I have submitted a support request to Qt Company, but I haven't received a response yet.

@NullNull iOS is not similar to Linux? What is the difference between these two in terms of using Qt?
