Below you see a couple of projects built with our DYO Framework. Most apps are actually built for publishers with their own branding.


Update July 1 2016  D.Y.O.  Version 1.5 update

The new 1.5 framework contains improvements on all areas.

Smarter and quicker artwork preparation
More advanced animations
More add-ons, puzzles, colouring pages, memory games
Better pagecurl and dozens of other small changes.



We have had numerous requests over the last couple of years from authors of illustrated children’s books who want their illustrated book made into an app or animated ebook.  We literally have had dozens and dozens of requests, discussions and emails with  authors, but in most cases initial development was just too costly.


Since then we have developed apps for ourselves and for other companies, but we also developed our own book framework. This framework is very suitable as the basis for most illustrated books. You can see this as a co-development solution, whereby the authors can decide which part they do themselves and which part we can do for them, thus making it more affordable.


We have built a structure that allows you to select what you want in your app. You can select which parts you want to do yourself and which parts we do for you.


You can start simple and add features along the way; you decide whether to start with one version for iPad and later on you can add iPhone or Android, Amazon Fire or B&N Nook.


Developing an interactive story app requires several steps:

• Create a story and the artwork.
• Define the structure and storyboard of the app, including the amount and type of interactivity.
• Record voice-overs, music and sound.
• Develop the app by combining all the different elements: graphics, text, voice, music, sound, interactivity, and animation.
• Testing, testing and testing.
• Prepare for the AppStore, publish your app to the AppStore, and wait for the approval.
• Sell your app, and do the marketing.

Things you can do yourself, or you want us to do for you:

• Prepare your artwork – if analog: scan, edit and correct.
• Define a storyboard and app structure (decide the flow, storyline, etc.).
• Prepare for animation and interactivity (you supply spot illustrations).
• Voice-over, music, sound.
• App submission, icon design, AppStore description, images for the AppStore.

We do the actual development based on our framework. We “feed” your content into our system, develop the interactivity and animation and add the voice-over, music and sound. During development  you can join our development team, so you can then download the app on your device and help us test and/or change it. You can make changes to your content and update it on our system.


We ask an initial fee for our system, based on the platform you have selected. After that, the price will adapt according to the amount of pages, interactivity and options you want us to arrange for you. Of course, we can help you along the way with each part of the process.



We can support/help you with each part of the process and will put you on track to do a lot of the work yourself. You do need a good working knowledge of photo editing software like Adobe PhotoShop to prepare your artwork. If you need more creative input with your story or drawings, we at OCG Studios or Roxie Munro in the U.S. can give you the advice/support you need.



You can be in charge of your own artwork and other assets you supply for the app, but we do advise you to have everything in the highest possible quality. We do not create original artwork or commission artists.
Your artwork should be professionally scanned in 300 dpi. If you want certain parts animated and the text highlighted when read, the text should be removed from the artwork. Also, animated parts should be taken out of the artwork and the blank spots filled. We will explain this more thoroughly to you. If your artwork is done in Adobe Illustrator or PhotoShop we prefer the original files.



Music can really add an extra dimension to your app. It can be purchased from stock libraries; we can have it commissioned specially for your app; or, if you are a musician, you can compose it yourself. We need digital files like WAV or MP3 in the highest possible quality.
Adding sounds to the app will enhance it a lot too. The sound of a bird or a car will make your app really come to life. These sounds can be homemade, or purchased from stock libraries. The sounds need to be clean(no static, cracking etc), so one WAV or MP3 per sound. Please keep in mind that a couple of sounds per page will add up, when you have a book/app with 15 or 20 pages. See where you can re-use these sounds.
All music and sound must be royalty-free. When purchasing from a stock library they’re usually royalty-free, but check the type of licenses the stock library company has.



This is important for a book app. People expect to be read to. When recording a voice-over, use a professional studio or engineer. Of course, you could do your own narration – just keep in mind that a good story with nice drawings needs a great voice. Or, we can recommend the male and/or female VO and producer used in our apps. We need digital files like WAV or MP3 in the highest possible quality, one file per page.



Animation and interactivity can make your app interactive and more engaging. Small animations are inside our framework, complex animations needs to be coded.
Each animated part needs to be cut-out from your artwork. Animations can be started automatically or when triggered, sounds and other effects can be added.



It is possible to add little games to your app, our framework contains several small games, puzzles, coloring pages, word games or can be made specifically for your app.
The sky is basically the limit but things that are not in the framework it needs to be build.



We can convert your “2D” book into a “3D” version, for example a popup book or a real 3D world, this is not something that is standard in the D.Y.O. framework but can be done.
Another possible solution is to add AR (Augmented Reality) to your analog book, when a certain part of the analog book is scanned we can make it come to life inside the app.



In our pricing system, you can decide what you want to do yourself or what we can do for you. Most options have a fixed price, but if you have special wishes/needs please let us know and we’ll make you a special offer. With the menu system you will have a clear indication of the price of most of the options.

When you contact us and give us an idea what sort of app you’d like to develop, you’ll get access to our pricing system. You pay 50% when we have an agreement on the price, 50% when the app is finished and ready for submission. Payments can be done using Paypal or Bank transfer.



We’ll test your app thoroughly, which is very important. During the development stage we’ll let you have your own pre-release versions of your app, so you can make changes and test it yourself, or let other people do some testing. For Apple you we can put the test versions on your Apple account, you can then invite people to join in testing or have a sneek-peek. With Android it is much easier you can just send your app to people and have them install it on their device.



We can do a lot of testing, but the app will get its ultimate testing when it is in the hands of your users/clients. We will support your app during a 3-month period,  if there are bugs they often arise during this period and we will fix them. Keep in mind that developing for iOS is a lot simpler than developing for Android. There are hundreds and hundreds of different Android phones/tablets and OS versions. It’s impossible to support them all. Especially some of the really cheap Android smartphones which lack certain features.


Sometimes Apple or Google will release new operating systems, and normally an app keeps working correctly under these newer operating systems. But sometimes changes are necessary for an app to keep running smoothly. If it is something small, we will fix it for you. However, if it is a big update, we will explain to you what needs to be done and you can decide whether to update or not.



Before you can submit, you need to decide on the price of the app. Take a good look at other apps – how they are priced. If your app has the same quality and amount of content as another app, you could use the same price. Read the reviews of these apps to see what people think of their price.
A good app needs a good strong icon. When people browse through the AppStore, the first thing they’ll notice is your icon. This icon image must be a powerful representation for your app. We can make an icon for you, or you can design one yourself (with our help if necessary).

An app in the AppStore needs a good, smart and short description. People tend to not read a lot. A description should be informative, succinct, and powerful. You can change this whenever you want once the app is in the AppStore. The AppStore also needs 5 good images, which we will supply for you: screens from your app, so people see what they can expect, before buying your app. These images can also be used to explain or promote certain parts of the app.



The Apple and Android stores now allow small video’s to accompany your app, these little trailers or teaser give people a good view of the app before they decide to buy, we can make these video’s for you or help you create your own. Apple is limited to 30 seconds and has strict  rules, Android appstore contains Youtube video’s and has a lot less limitations. Here are some examples



When your app is finished it needs to be submitted to Apple, Google or Amazon for review. In all cases you need a developer account. At this time, for Apple / iOS this is $99 per year. For Google/Android this is $25 a year; Amazon is $99 a year. So you need to request a developer contract, which must be renewed each year.
When an app is submitted, it can take some time before being approved, especially with Apple (up to 2 or 3 weeks). Sometimes an app gets rejected. This can be a technical issue, a rights issue or another reason. Apple will then explain it to you (Apple can be a little strange sometimes).

The Google Play AppStore is a lot less strict, so usually it only takes hours. When an app is rejected because of rights, or because another author or developer finds that the content is theirs instead of yours, you have to solve this yourself. If it is a technical reason, we will fix it.
Apple, Google and Amazon all take their share of your app profits. This varies between 30% and 35%, depending on country and currency. Apple/Google/Amazon pay your royalties once a month, but right after submission it can take up to eight weeks before payments start.

It is possible that Apple or Google really like your app, they put it in the ” What’s New” section or “Editor’s Pick” this can make a huge difference in sales. If Apple or Google really really likes your app they can put it on the first page of the AppStore or Google Play AppStore, this requires extra artwork (mainly bigger) for use in the store.

PLEASE NOTE: When you supply us with your artwork and story, we expect you to own it. If the content is claimed by a third party, it is yours to solve.  Our last payment is due at the end of the development when the App is submitted but before the AppStore release. When the issues are resolved and you can submit to the AppStore again, we will do that for you.



Writing a wonderful story with nice artwork and developing a great app is step one. When your app is in the AppStore, you need the world to know that your app is for sale. We can help you with basic information on where and how you can promote your app, or we can direct you to companies who can do this for you.

App marketing is a lot of work, but if you have your own contacts and a lot of Facebook or Twitter followers, it can be made much easier.

App marketing is a continuous effort – new apps arrive daily and they all want the attention of the potential buyer. But if you have a great app and a great story, there are over 800 million iOS devices and a lot more Android devices out there, so the potential is huge. A $1.99 app can generate a serious income. There are very wealthy app developers and there are developers who haven’t made a dime. But a good story, with nice drawings, a good voice and a well-developed app are the first steps to be an independent developer. Good and clever marketing will do the rest.
There are dozens of ways to get your app attention, here are some tricks that can help.

• Create a story and the artwork.
• If you have more apps you can cross-promote your apps inside your other apps.
• If you have an app with a certain theme you can try to market them on site that have information about this theme.
• App reviews on big sites, or paid reviews, we have lists of sites you can contact.
• Make friends with other app developers to see if you can cross-promote.
• Play with the price, make it free once in a while, promote and change the price back, you can control your price on the developer portals of Apple and Android.
• Your market can be the whole world, depending on the language, target a country at a time.



When you contact us for more info, we will send you a DYO link with a form. On this form you can select what you want to do yourself or what we can do for you.
