How to Protect Your App Idea

Copyright

Before it can be legally protected, an idea must first take some kind of physical form. This could be anything from a few words on the back of a napkin to detailed technical drawings. Once the idea has taken the physical form it is automatically protected by copyright in most countries, with no further action is required.

Just because your idea is protected by copyright though, doesn’t mean somebody else can’t have a similar idea. In order to legally challenge a competitor you would need to prove that you came up with the idea first. It is therefore important to send your idea to a lawyer or register it using a copyright service so you have proof of creation date, verified by a third party.

Trademarks

Put simply, an idea can’t be trademarked. Your specific implementation of that idea can be tough. Let's say your idea is a social network for beekeepers. The idea itself cannot be trademarked but your striking black and yellow striped interface design, catchy buzz sound effect when someone clicks ‘like’, and app name – ‘Buzzbook’, can be. Each aspect of your implementation would likely need to be trademarked separately, so this approach can get quite expensive.

Trademarks are popular with established companies who want to protect their brands but are of less use to new startups that don’t yet have a well-known brand to protect.

If you want to create apps for smartphones and tablet PCs, then the Android SDK would probably be the best option to develop your dream application. The software development kit gives you access to key developer tools and API libraries to create apps, test them using a simulator and debug them. Unfortunately, app development isn’t easy. You must have coding skills, even if you are trying to build a simple web app.

For most app developers, learning programming languages can be tiresome and a waste of time if they intend to build a simple application. Thankfully, there are some great Android app makers that allow developers to create applications without needing any programming skills.

App makers have a simple drag-and-drop interface that allows you to make a wide variety of web applications, travel/hotel guides, business websites, video apps, and HTML 5-powered apps. Several app makers will also let you monetize your app and earn passive income. Here are some of the best app builders that are available for free online:

1. Apps Geyser

Apps Geyser lets you create fully interactive applications. These apps will include social sharing, tabs, messaging, and video units. By taking advantage of HTML5 enhancements, you can build an app from scratch and also monetize your content.

Apps Geyser was one of the first free app builders on the Internet that allowed users to snatch content from a website and create a nice little app out of it. With time, the online app builder introduced new features, including HTML5 support. Now you can make your web apps totally interactive by adding amazing gadgets like video units, HTML code, news aggregators, and niche apps. The current version also lets you make simple games, Facebook pages,s, and quiz apps. You should try out Apps Geyser's quiz module if you want to build an app like Trivia Crack.

The best part is that you can monetize your app by allowing ads to appear on it. Don’t want ads? Well, the online application builder also lets you create an ad-free application that you can sell via the company’s online store or Google Play. To apply for the monetization option, your app needs at least 100 installs daily. If you are interested in building simple apps and monetizing them, you should try Apps Geyser.

2. iBuildApp

iBuildApp offers a variety of templates and features for your Android applications. You can easily customize your app’s look, add images, and buttons and choose the best color themes for your application.

The tool lets your mobile app creation process easier by providing niche-specific features. Want to build an app for a bookstore? Planning to make a home loan calculator? iBuildApp has the right “feature” tailor-made for your needs. Features are categorized into social, form, media, e-commerce, and utility. So if you want to make a shopping app, just go to the eCommerce category and choose a layout that suits your application requirements.

The site has three pricing options. The second option should suit those who want to monetize their app. For those who want to distribute their app for free, $5.99 per month plan would be a better choice. Unfortunately, there isn’t any free option available for users.

Infinite Monkeys not only lets you build an app but also develops a mobile site for Android devices. Its HTML5 support makes sure your website renders perfectly in all smartphone browsers. Now that Google’s mobile algorithm update has launched, it has become very important for webmasters to have a mobile-friendly site and this tool makes their dreams come true.

Among paid Android app-making tools, Infinite Monkeys has the lowest pricing options starting from $1. However, I would suggest choosing the second plan as it provides several offers such as app submissions to Google Play and iTunes, HTML5 mobile website builder, updates,s, and live chat support.
