Probably the best one of the DAPP-stats sites. Even though it's heard that it often takes weeks for them to publish your dapp. They prefer the paying customer probably.
Also like in most of these sites the data is often pretty wrong, and when you compare some sites against each other you will see that.
A lot of these DAPPS are very short term and only run for days sometimes, so a big portion of what you see does not exist anymore.

The downside about everybody being able to publish any application is that a massive amount of these things are scams and similar projects.
Another issue is that they have thousands of frauds and scams listed. Everything, no matter how nice people make up the names for example, 'high risk' 'ROI games', 'investment plans', 'hiyp' are fraud and scams, that's a fact.  
So be aware that everything "high risk" is a Ponzi, a pyramid scheme, or any other similar type of fraud. People don't care and play things like that anyway, but just be warned as these platforms promote thousands of those scams. People have lost millions in this kind of DAPPS . 

But for the website itself, it does pretty well what it should and has a lot of listings.
