Yeah- sometime the next day just say "It was a pleasure spending the evening with you. Let's get together again sometime soon". If you can, work in something particularly memorable or funny from the evening before...maybe she mentioned some kind of quirk she has and you can give her a funny nickname based on that. Adding something like this is all about being memorable and creating an emotional response.
Don't wait too long. You need to create "emotional momentum".
What was the messaging app?
