There are several dating apps that offer a good user experience without requiring users to pay for premium services. Here are a few options:

1. Bumble: Bumble is a popular dating app that allows users to swipe through potential matches and send messages to mutual matches. Unlike other dating apps, Bumble requires women to initiate the conversation, which can be a plus for women who prefer to have more control over who they talk to.
2. Hinge: Hinge is a dating app that's designed to be more focused on finding long-term relationships. Instead of swiping through profiles, users can like specific parts of someone's profile (such as a photo or a prompt answer) and send a message to start a conversation.
3. OkCupid: OkCupid is a dating app that uses a matching algorithm to connect users based on their interests, beliefs, and preferences. Users can answer a series of questions to help the app find compatible matches, and can send messages to mutual matches without needing to pay for premium services.
4. Tinder: Tinder is one of the most popular dating apps, and allows users to swipe through potential matches and send messages to mutual matches. While Tinder does offer premium features like unlimited swipes and the ability to see who's liked your profile, users can still use the app and send messages without paying for these features.

It's important to remember that the "best" dating app will depend on your individual preferences and what you're looking for in a dating app. It can be helpful to try out a few different apps to see which one works best for you.
