September, 13, 2018 – Amsterdam. Wattl is pleased to announce that it will exhibit at IBC2018  

Wattl is the broadcast solution that addresses how companies can access younger audiences online. Considering YouTube alone almost 5 billion videos are watched on it every single day. On mobile, YouTube reaches more 18-49 year olds than any broadcast or cable TV network. Users want to discover new video content every day and broadcasters want to be seen by a demographic that doesn’t watch TV.

How can the two be brought together?

Wattl is a platform brings together user generated content with broadcast media creating new content discovery opportunities for viewers and creators. By ditching the linear feed interface, Wattl uses patent pending video wall technology to allow access to more videos at once. Trending and popular videos stay, the rest delete, meaning there’s always something new and relevant to watch.

Visit the Wattl stand to meet the co-founder and CEO, Emma Ryan. She will be doing regular demos and is available for meetings throughout the exhibition. 

“Visiting IBC is important to Wattl right now as we have just launched our Wattl Worlds product. This now allows broadcasters to own their own space within Wattl. They can start interacting directly with their viewers with their own content but more importantly with the viewer’s content too.

IBC is the world’s most influential media, entertainment & technology show for professionals engaged in the creation, management and delivery of entertainment and news content worldwide. It is important for Wattl to be there and meet our peers and clients in the industry, be it a student or CEO, an innovative start-up or media superpower. Held at the world-class Amsterdam RAI, 13 – 18 September 2018, IBC brings together over 57,000 attendees from more than 170 countries to grow the industry of media and entertainment.

September 11th, 2018 – Amsterdam – Wattl is excited to exhibiting their innovative video sharing platform to the world’s most influential media, entertainment & technology businesses.

After extensive technological development, it is ready to revolutionise the way videos are accessed, making discovering new digital content easier.

Wattl is a fun, interactive virtual world that brings content makers together in one innovative sharing platform.

Emma Ryan, co-founder and CEO said “Wattl is an incredibly simple idea. It’s a massive video wall showing you new and trending videos, like an eye on the internet. With so much content being uploaded daily it’s becoming harder and harder to find relevant and engaging videos.

 Wattl will keep you ahead of the curve by showing you what is popular each day and deleting old content. Find new YouTube stars, watch your favourite team or celebrity, and best of all be part of the grid yourself by uploading your own videos next to your favourites to be discovered”. 

Dr Matthew Ryan, co-founder and CTO said “Wattl is an exciting technical challenge that I love working on. We have an international patent pending on the video platform and we are using the very latest cloud and AI technologies to deliver the product”.

Wattl is taking on established brands such as YouTube, Facebook Watch, IGTV and Snapchat. This small team has moved from their kitchen table to shiny new offices, with interns featuring heavily among their staff. They are nimble, hungry and innovative, bringing something unique to a massively expanding market. Their vision is to mix up on-demand, broadcast and personal footage all on the same platform. Wattl is an app and is available to download from the Apple App store HERE.

The Wattl iOS App

Hello, my name is Dr. Matthew Ryan, I am the CTO and developer of the Wattl platform.  In the coming weeks and months I’ll be posting regularly on our progress in the development of Wattl.  It has been an exciting time so far, with highs and lows – long nights, hard work and finally a working product!

The Wattl platform is made up from a number of components, comprising the client which is a native iOS app, and the server side.  I’ll start on the first blog post by talking about the iOS app, and will cover the other aspects in later blogs. Be sure to sign up to the newsletter so that we can let you know when new blogs are posted.

iOS App

The iOS app is  a native app written in  Objective-C using XCode. The app has 3 main  sections, namely the wall, feed and profile.  To navigate between the pages, we developed a prism navigator.

Prism navigator

To navigate between sections you drag from the edge of the screen, which rotates the prism. This is implemented as a 3D prism with 3 sides – each side being a page. As you rotate it, the prism has perspective, and you can see behind it.  We also model the lighting to give a realistic shadow to sides as they turn away.

To navigate between pages, drag from the edge of the screen

The prism has inertia, so just for fun, you can ‘flick’ the prism and it will keep spinning for short time.

We stop video playback of the wall while the prism is being rotated to ensure it rotates smoothly, but actually the iOS views are still being updated. You can see this yourself if you go to a profile page with many images, and then rotate the prism slightly while the images are still loading.


The wall section is where you can create and view the walls. The first screen you see is a list of the walls, containing the public Wattl wall, and a list of the private walls you have access to.

In wattl the first page you see lists your public and private walls

You can select the wall you want to view by tapping on the row. Each wall is a zoomable grid where anyone with access to the wall can upload images or videos.

The wall has by far been the most difficult and complex part of wattl to develop. There are many challenges to make it work, with many (sometimes conflicting!) goals.

The wall uses many different technologies to work, and includes:

  • Database to store the information about the cells
  • Cloud storage to store the media
  • Virtual servers to maintain and update the media
  • Micro-services to implement an API for the app

More details about the technologies involved will follow in future posts, so let me know in the comments what you’d like to know about.


In wattl you receive a notification when things happen you might be interested in. For example, when you get invited to a private wall or someone posts a comment on your cell. All these feed items are listed on the feed page, which shows the relevant cell, the user and other info such as the comment.

Feed shows notifications of things like new cells, or comments

We use push notifications which are triggered when certain events happen. So for example when a user uploads a new cell, we send a push notification to all the people who follow that user.  If the followers have not enabled push notifications, they will just see a new item in their feed when they open the app.

There are a number of improvements we will be making to the feed page, the first being a badge to show the number of unread items.


Each user has a profile page, which shows things like username, bio, profile picture and public cells they’ve upload.

Profile page in wattl shows details on each user

On this page you can follow /unfollow and see who as pulsed your cells. There is also a settings cog at the top to open the settings page.


I hope you’ve found this first post interesting, which was just a very brief overview of the main sections in the iOS app.  The coming posts will talk more about the app, the server and our day-to-day experiences, challenges and successes!
