Tools for Android and iOS Prototyping

Mobile app prototyping has always been a great pain for designers and developers. Creating application interface with responsive mobile technologies is not effective and mostly demands hundreds of lines of a JavaScript code and depicting touch gestures with annotations.

It is not intuitive. It is really chaotic when you are pitching your application in front of the public and say something like “imagine how the toolbar is now swooshing in front the top of the screen” while desperately waving your hands and trying to imitate the gestures of a touch.

When we were the high school students, such presentations were funny. However, now you probably want to strive for something a bit higher and find the best app prototyping tools.

Fortunately, there are prototyping tools for mobile app that allow an easy way of creating app prototype. In this article, we will consider the best prototyping tools and their main features.

Making a prototype app with is a platform designed for app prototyping. It was developed by Labs Division of SNQ Digital and launched in 2011. Initially designed for mobile devices prototyping, has extended to provide prototype applications for every item with a screen interface like digital camera interfaces, Smart TV’s, airplanes, cars, and gaming consoles. This service does not require coding and utilizes a convenient user interface.

For several years, has been creating tools for prototyping mobile apps and solutions. Recently they have introduced a new item that enables to view prototypes for iOS and Android apps in a more realistic way.

For an average user, it means that they have an opportunity to edit a prototype quickly and view it as a mobile app. Other similar tools allow doing this on a mobile browser only.

The other great thing about Proto is that its tools are easy to use. Even if you are not a Photoshop designer, you will be able to create nice prototypes with it. The elements could be easily dragged and dropped onto the screen. You can add images, buttons, and text, as well as links to the other screens.

If this is not enough for you and you want to have your design under a full control, you can customize your mobile app prototype. You can start with a blank template or project and create your way to a final version of a prototype.

Interface is rather simple and intuitive. In fact, you can easily learn it by just fiddling around than following tutorials. Take some time to explore interface, the rest will depend on your ideas and creativity.

Creating a mobile prototype with Fluid UI

Fluid UI is another alternative for creating prototype mobile apps. It is a browser-based prototyping and wire framing tool created by Fluid Software. It is used to craft easy and fast design of mobile touch interfaces. Fluid UI can be used for dynamic mobile application prototypes for iOS and Android.

It helps to export the screen flows, share and collaborate with the other people.
