How to Move From a Dating App to Text
Moving off-app can make planning easier, but it is not a required milestone. Some people prefer to stay in the app until after meeting.
Ask after some rapport
Once you have a comfortable exchange or are planning a date, you can offer your number instead of demanding hers.
Respect the platform preference
If she would rather keep chatting in the app, that is not automatically rejection. Continue only if the conversation itself remains reciprocal.
