Now, this is a subject on which mobile app developers have very strong opinions. Anyone who has discussed the issue with an app developer can testify to how strong the feeling can get on it. People who frequently use mobile apps, are also bound to have an opinion on the topic, at least most of them. In the last year or so there has been a shift in favour of HTML5 and can safely be said that most companies prefer this option. It is much easier to learn HTML5. This means that the debate is a lot less fierce than it used to be, although it doesn’t imply that native apps are altogether abandoned. Let us look at the facts and pros and cons of each option and then we’ll have better understanding of both options. Of course, most people choose to rely on their own experience when it comes to apps, and there’s nothing wrong with that. 
Generally speaking it will always depend on what you need from an app, what are your expectations, what is the purpose and how much are you willing to pay. That being said, it is clear that the preferred option may depend on the type of the mobile app in question. So, even if generally HTML5 is the more popular option, it doesn’t mean that some business won’t choose Native apps.
A lot of people have praised Native apps in terms of user-friendliness. That sure makes sense, considering that Native apps are specifically designed to serve a purpose and they often provide a unique user experience that can’t be matched by HTML5 apps which are usually designed in a way that’ll enable them to be used on numerous platforms with very few adjustments. Creating a quality Native app requires a lot more time, effort and money compared to a HTML5 app and it is usually limited to a single platform. So, often Native apps provide better user experience and generally have better security.
However, always bear in mind that if you want to develop a Native app for both iOS and Android you’ll need to pay at least twice as more, because you’ll need two teams working on each. In addition, it is a lot more difficult to create a Native app, because a lot of the stuff required for it, cannot be coded in Java and you’ll probably need better skilled developers, who are certainly going to cost more. In short, the quality and security of a Native app do come with a price attached. 
When the HTML5 appeared in was behind Native in many respects. That changed over the years. The main point of the HTML5 was that it was designed to solve the issues of compatibility and speed. It was supposed to provide a solution of designing an app that could be used on multiple platforms at a much lower cost. In addition, it takes less time to create a HTML5 app and a lot of front-end templates have been developed. These are the key reasons for the growth of HTML5 popularity.
Many businesses, including global companies, real industry giants switched to HTML5 apps, either completely or for mostly. A carefully designed HTML5 app, in Java, which is one of the easiest languages, will run on any device. So, it is cheaper, simpler and applicable on any device. This is the core reason why HTML5 is the preferred options. Online casinos and other gaming websites alike are only few of the many online industries that switched almost exclusively to HTML5. It does make perfect sense, online casinos want their apps to be available at as many platforms as possible, with mobile gaming on the rise, they tend to develop dozens of new games in short time spans, so they naturally want things as simple and as fast as possible.
Offering a wide selection of online games is one of the ways in which casinos try to attract new players, with other methods including bonus offers, usually featured on websites specifically designed to feat that purpose. Site such as NoDepositCodec.com offer all manner of bonuses and prizes can be quite lucrative. In addition, they take extra care of online security anyways, so that’s not an issue for them. With Java scripting getting easier and simpler, the history of HTML5 seems secure, although that doesn’t mean that Native apps will disappear altogether. Each to their own as they say. And for those who can’t make their mind up, hybrid apps are also a possible solution. The overall conclusion, still, is that HTML5 prevails.
