Submitting an app proposal


So, you’ve decided you have a great idea for an Overwolf application. Now what?

Before you jump right into developing your app, why not tell us a little about what you have in mind? This means putting together a simple app-proposal presentation, giving us the details on what your ideas are, what kind of features you would like to implement, and some mockups so we can see what the app will look like.

The idea is to show us what your app is all about before you invest time and effort into development. It also gives us a chance to give you feedback on the app, and to let you know if the Overwolf Appstore is the right place for it.

Once your presentation is ready, submit it to for a review. You will receive our feedback within 7 business days. Once your proposal is approved, you can go ahead and start coding. When your app is ready, simply submit it for a full review.

Not ready to submit a proposal just yet? Why not spend some time playing around with our SDK to get a feel for how our apps work? You can find all the resources you need on the demo app section of our documentation page.

Tips for a Great Proposal

To help you prepare a kick-ass proposal, here’s what we recommend you do first:

  • Get to know what kind of apps work best

    – Visit our apps showcase to understand what kind of apps Overwolf users love to use. This is really important, since Overwolf applications must provide real value for gamers, and must answer real needs.

  • Check out what’s already out there.

    Look over the apps in our Appstore, especially the ones that are similar to your proposed idea. Think of what your app can do better, or what it can offer that similar apps don’t.

  • Review the documentation

    – Whether you’re new to Overwolf developers or a returning developer, it’s imperative you go over our documentation. We’re constantly updating our documentation with current features, so it’s important to remain up-to-date on all the tools and options you can harness.

  • Why would an app proposal be rejected?

    Here are some reasons to keep in mind when you prepare your presentation:

    • The app does not offer real value to gamers.
    • There is already an app that provides this service or features, and therefore would not provide any new value for our users.
  • Questions? Just ask, we’re here to help!

Prepare Your Proposal

Submitting your app idea for review is easy. We’re not looking for a complete set of technical documentation at this point. Instead, we’re looking for a clear, concise description of what the app is and how it will work. We also want to see a mockup of the UI. This proposal (and the app itself) must be in English, although you may offer other languages in the completed app.

Your app proposal must address three key points:

  1. Describe your app.

    Tell us what your app will do, and how it will work. Explain the main features, and provide some basic details on how you intend to implement them.

  2. How will your app help Overwolf users?

    Explain how your app will improve their gaming experience. Is there a similar app in the Overwolf app store? If so, how is your app new, different or better?

  3. Show us what you have in mind.

    What will the app look like? Provide us with a mockup of the app as a PPT/X or PDF, or send us a URL with your designs. We’re not looking for highly polished design work here, we just want to have a basic idea of what the UI will look like and how the app will work. Walk us through the entire UI, providing details on all of the app elements, settings, etc.

That’s it! Your proposal is now ready to be reviewed by the Overwolf team.
