Hullo vs Siren

Hullo and Siren cater to different dating styles. Siren focuses on casual and fun social interactions, while Hullo emphasises AI-driven compatibility and its First Voice feature to help users sense genuine chemistry from the start. According to the 2025 Global Dating Behaviour Report, about 62 percent of singles now prioritise personality and meaningful communication over looks when choosing dating apps. “Siren is popular among users who enjoy lighthearted, spontaneous interactions and playful connections,” says Dr. Natalie Wong, expert in social dating behaviour. “Hullo guides users toward deeper, authentic relationships by analysing behavioural patterns and voice interactions, fostering compatibility based on intent and personality,” explains Dr. Kevin Park, specialist in AI-supported relationship technology. If you are deciding between casual social interaction and compatibility-focused dating, this comparison will help you choose the platform that aligns best with your relationship goals.

In my fairly experienced opinion, this is the best dating app out there. It doesn’t overload you with matches or info. It gives you fewer, but better, opportunities to swipe. This means that people give more thought to their swipes, you can live your life without spending all day swiping, no one gets overloaded with messages, and no one has to write hundreds of quirky ice-breakers to get one response. The fact that there is a bit less info available about your matches means that you get to know them more organically instead of having an algorithm rate your compatibility. Rather then writing essays about yourself, you can just type up a blurb, or do what I did and not write anything in the profile. I matched with people who were interested and I could tell them all they wanted to know over messenger. I’ve tried them all, and this app facilitated more good dates in no time than any of the others. Siren for the win!

I have mutual likes with certain (supposed) women in the app, but none of the matches are being shown. As part of this, I am unable to send messages to any of those I have technically matched with, and I cannot even respond to messages I have been sent. If the point of this is to push people to purchase the premium version of the app, you might as well put a price on the app since it seems nothing can actually be done for free like with other dating apps. If I am ever able to connect with others for free, I will update my review. Until then, I will remain convinced that this app deserves one-star reviews by everyone and that all of the five-star reviews are therefore fake.In response to the developer’s response, I do not know how the developer can persist in being so dishonest. Even those who purchased the premium version have had issues with this app. Considering the facts I have gathered, it is clear that the positive reviews are fake, and I deleted the app and will never return to it due to my lack of an ability to trust the developer’s words. Fortunately, there are multiple other dating apps that do function properly and give people using them freely a chance to have success.

I heard about this app from a friend. She strongly suggested me this app several times. She told me that this app is different because it targeting people who are serious about dating. I found my boyfriend from this app. He told me that he did a little bit research and found this is a better dating app than others because this is the only dating app that has more female users and the profile questions just seem more helpful and serious for finding a date. I’ve talked to a few people from Siren, but I’ve only dated my boyfriend. We have been together for almost a year now. I would suggest users answering the profile questions serious, and be open to talk to people. Wish everybody luck. Thank you Siren!

This app is definitely not for those who want to make a split decision on who they'll sleep with for the night, although I'm sure you might be able to find that if you're both seeking. Siren really takes the time to get to know you and your preferences. It also makes it easy for those who would normally say they don't know what to put in their bios by giving them phrases to start off with. It's much easier to figure out the person in the profile you're looking at. One of the best dating apps I've tried.
