Add seamless, cross-platform, quality inking expression to your apps with WILL. It’s ink for the 21st century

Ideas shape the world around us. To make ideas come alive, you need to capture, shape, share, and collaborate with those ideas. Your ideas should not be held back by the technical restrictions of a keyboard or mouse. True creativity requires creative expression. We need the power of digital ink.

Digital ink for the 21st century is flexible, collaborative, ubiquitous, and expressive. No longer reserved for graphics professionals, digital ink is now available for everyone through WILL, the Wacom Ink Layer Language.

Enter WILL, the global standard for universal ink

WILL gives you the power to add powerful expressive tools to your new or existing application. With WILL, your users can share and collaborate with drawings and handwritten notes quickly and seamlessly, on whichever device they prefer, using any input from a finger to a Wacom enabled pen.

WILL provides cross-platform, high quality, universal ink. Create an idea on the iPad and continue refining that idea on a smartphone. Collaborate in real-time with coworkers in another country, regardless of platform. Release your app from the restrictions of text entry and allow the natural flow of ideas.

Why add WILL to your app?

Smartphones and tablets are overtaking laptop and desktop computers as a primary computing devices. Touch screens are everywhere, and a fast growing number support pen input. Stand out in the crowded app marketplace with precision input and advanced features enabled by WILL.

  • Business - For business users, WILL enables new categories of applications, including advanced note-taking, document markup, and online collaboration with digital whiteboards. Imagine a completely digital workflow enabled by digital ink, sharing with others worldwide. Work with remote colleagues on a digital canvas the same way you would use a whiteboard.
  • Signature - Want to take your paperless workflow to the next level? Add secure digital signature capture. Integrating WILL along with Wacom’s Signature solutions gives the flexibility of WILL ink input with the security of biometric handwritten signature capture.
  • Consumer - In the consumer world, WILL allows enhanced personal expression, connecting us more closely with the people and ideas we care about most. Instead of typing another emoji, you could share your expression directly with your friends.

Inking isn’t just for sketching, although it’s great for that too. Advanced metadata and precision input make WILL a natural fit into many industries.

Digital pen adds more

For the best experience, create applications that use the full feature set of WILL combined with a Wacom enabled pen, like the Samsung S Pen or Wacom feel™ technology devices. Bluetooth pens like the Bamboo Stylus fineline add advanced features to iOS and Android devices with standard touch screens.

Wacom believes in a world alive with creativity, so WILL provides digital ink to any device supporting a touchscreen or digitizer, even if your only touch is from your fingers.

  • Individuals (who have reached the age of majority in their jurisdiction of residence at the time of entry); Teams of eligible individuals; Organizations (up to 50 employees)
  • Organizations with over 50 employees may compete for the non-cash Large Organization Recognition Award.


Main Requirement: Create ink-enabled apps using the WILL SDK, or update an existing app with WILL to add ink inputs. [Note that while WILL is designed to work with Wacom or Bluetooth enabled pens, no special hardware is required to integrate WILL into your application. You can use WILL with touch input as well as enabled pens – so go forth and code!.]

Eligible Platforms: 

  • a native smartphone or tablet app (iOS or Android)
  • a web app (mobile or desktop)
  • a desktop app (Windows PC)

Supplemental Material: You must submit a demo video (hosted on YouTube, Vimeo, or Youku) that walks through the main functionality of the solution via screencast or video. You must also submit at least one image/screenshot of your working solution.

Language: All submission materials must be in English or, if not in English, you must provide an English translation of the video (you can include subtitles or audio bubbles), the text description, and the testing instructions as well as all other written materials submitted. 

Online Stores: Your app does not need to be publicly accessible online to be eligible for the competition. However, finalist submissions will be required to post their applications in a publicly available store before the winners are announced in January 2016, so making applications public early is encouraged. 

New & Existing Solutions: Solutions may be newly created or pre-existing. If you are submitting an existing solution (developed prior to this competition), your solution must have integrated WILL after the start of the submission period AND you must have updated the application to include new features or functionality requiring WILL. If you are entering an existing solution, you will be required to explain the new features in the submission form.
