We are developing "Liberapp", the HTML5 application platform for smartphone, and the cryptocurrency token "Libreum" (based on the ERC20 Standard), the ecosystem for evaluation and support to HTML5 application publishers, reviewers and users. Now(Jan 2018), we are considering to launch our ICO within 2018.

Our mission is "The magical world for you to distribute your applications openly and freely!". A few OS vendors monopolize channels for native application distribution. Constrained environment compromising freedom of expression is social issue. And new technology for HTML5 such as service worker is emerging. In these social changes, we will launch a new generation HTML5 application distribution platform "Liberapp". In addition, in order to build the non-centralized ecosystem to evaluate and support applications, we issue cryptocurrency token "Libreum" making full use of block chain technology and build a mechanism to directly connect creators ·, consumers and curators.

Liberapp Inc was established in December 2017. We began operating in January 2018. The reason, of announcing the start of consideration at this timing, is to accept the opinion of everyone of users, media and publishers around the world involved in mobile app business for building the best platform. In order to change the world, we are seeking partners / advisors as many as possible, who could support.

About Liberapp Inc.

Liberapp Co., Ltd. was founded in December 2017 to launch the platform that enable developers to develop and distribute applications freely for smartphones. Motoyasu Yamada, founder and CEO of Liberapp Inc, established Spicysoft Inc. at the end of 1999. In 2001, he launched "AppGet", the mobile phone Java application posting and sharing platform. Early in the mid-2000s, most popular mobile games in Japan, such as "Chari-so (Bike rider)", had been posted to "AppGet" by individual young creators. these games had led the Japanese game culture of mobile phones. Three people, including members who participated in the development of "AppGet" for over 10 years, started preparing business from January 2018. Liberapp is widely recruiting members and partners for business expansion. Please feel free to consult us.

Our concept

HTML5 application platform for smartphone


  • With SNS, HTML5 applications can be shared with URL only. Playable in 0 seconds without installing from the link.
  • Settlement platform optimized for mobile applications where credit cards and cryptocurrency tokens can be used.

No pre-reviewing, open decentralized distribution.


  • No pre-review. From casual games, to applications that could not be delivered at existing stores, can be delivered freely.
  • Platforms themselves do not have media. We release application data to the outside. Curators, such as game review media, bloggers can build their own portal or media for HTML5 applications.

Evaluation ecosystem by cryptocurrency token "Libreum"


  • More tokens to creators and publisher who posted applications that were played more and more longer.
  • More tokens to curators who dug up and introduced awesome applications.
  • More tokens to people who evaluated introduction articles of applications created by curators earlier, and people who viralized applications.

Issues to be solved by us.

Improvement of business environment for HTML5 application on browser


  • Currently, the information of HTML5 application is not aggregated. Therefore, the user can not easily search HTML5 application.
  • There is no settlement mechanism to monetize the HTML5 application.

Deadlock in the native application market oligopolized by monopolist companies.


  • Due to the profit of OS vendor's own business, restrictions to the distribution of competing applications and to delivery and billing methods.

Dependence on high-priced charging & soaring marketing expenses

Waste billing

  • Because it depends strongly on freemium, it is difficult for business models other than business models forcing high pricing, to come into effect.
  • The number of releases of new applications has drastically decreased due to the collapse of business models other than high-priced ones that bring high revenue to OS vendors.
  • Due to that influence, business such as review media playing the role of spreading new applications is struggling.As a result, there are fewer ways to appeal new applications. Mass marketing is required and it costs a lot of money.

Opened the world of closed markets of feature phone applications .

The mobile Internet in the world began in i-mode born in Japan in 1999. Also, the world's first mobile phones that can download and execute applications(i-appli) were launched in 2001. However, the i-mode portal "i-Menu" was a closed world where only a few major companies could join. So we started application posting & sharing service "AppGet" in 2001. There like the Internet, everyone can deliver applications on mobile phones, and everyone can created their business with applications.

"AppGet" changed Japanese cell phone game culture 20 years ago

Early mobile phone applications were dominated by ported titles from home game devices provided by major game companies such as Tetris. Gradually a lot of mobile applications began to be posted to "AppGet" by creators of high school students and college students who supported mobile phone culture. Then "Chari-so" (English title is "Bike Rider". Run and jump game.) which was enthusiastically popular to high school students at the time were born. When questionnaires were taken on the street, the majority of the high school students answered that they were playing it. This monster title was not created by a professional, but was created by the young creators' hands. We believe that it is not an exaggeration to say that we contributed to a part of Japanese mobile phone culture.

Smartphone applications world where freedom was lost by monopoly through vertical integration.

However, in the smartphone era, the market for applications is oligopolized by Apple and Google which provide OS and devices. Especially Apple's unjust acts such as restricting other companies competing with their business are in doubt. Since the era of smartphones, unfair regulations and opaque judgment led to a liberating place.Since the era of smartphones, unfair regulations and opaque judgment led to upset free and open market.

Overcoming the past HTML 5 error and trial

In the early days of smartphones, HTML5's challenge by Facebook etc. did not succeed. However, the specifications of devices have evolved and the technology of HTML 5 has evolved. It is now time to launch the HTML5 application platform "Liberapp" to regain open and free world!
