About Universal Zoom

Universal Zoom is a unique educational application that is designed to let you explore and experience the notions of SIZE and SCALE. The app presents a sequence of objects TO SCALE from the subatomic particles to the observable Universe itself. This application is suitable for a variety of subjects such as Science, Geography and Engineering and a range of ages from 4 years and above. The application is free from in-app purchases and in-app adverts.

Universal Zoom Review

Although this application is suitable for all iOS devices we recommend that the application is used on a tablet device to gain the best user experience. If the user is to view the application on a smaller device, they are advised to view this in landscape mode.

Upon opening the application, the user is directed into the apps beautifully presented scaling system. We found that the screen starts with a lot of information and the developers should consider the option for an app navigation tutorial here or an app instructions overlay to highlight the apps features and navigation.

The application covers hundreds of objects from animals to buildings to planets and a range of subjects such as Chemistry, Biology, Engineering, Geography, Astronomy and many more. Each object has been set on a movable scale in comparison to the other. The way in which the high quality graphics zoom seamlessly back and forth is very impressive. It is clear that this application has a vast amount of content and the learning opportunities are endless.

The top right hand icon displays a ‘Settings’ menu where the user can turn the music on or off, remove the narration, change the language of the narration, increase the text size and most important of all change the system of unit of measurement. This is ideal for countries who use different measurement systems. The ability to increase the text size also helps the navigation of the objects and enables users with smaller fingers to choose the desired text.

The measuring units displayed on the axis on the app really help the user with scale and introduce them to new units of measurement that they may have never used before from the Planck Length to 93 billion light years.The navigation bar across the top of the screen is also ideal for ‘quick start’ scaling where the user can jump to any object displayed within the bar. 

What we love about this app is the ability for the user to explore the application and really experiment with the comparison feature with objects that they may never have seen before or have the chance of seeing. As you can imagine the scale will change with the objects viewed and the experience is enhanced further with the wonderful sound that changes as you move through the different environments such as mountains and space.

Each object on the scale contains further information. This can be accessed by clicking the object or text. The narration will read the objects title and the user is then required to read the rest. The developers may consider two changes here; the option for the other text to be narrated so those with poor reading skills can listen to the description and also a recorded natural voice rather than a voice that is computer generated as this can often pronounce words incorrectly. Further information can be displayed by clicking the objects name in the blue text. This links the user to Wikipedia which is ideal for those who wish to explore further. Once again this adds to the user experience and increases the apps content and versatility. The user would also benefit if the chosen object had the metric sizes displayed when chosen rather than reading through the remaining text.

As mentioned earlier there is an option to ‘compare’ one chosen object with another. This is great fun and really puts into perspective how large or small some of these bodies are. For instance, who would have known that Mount Everest is 27 Eiffel towers high! The ability to photograph your own objects and add them to the scale might be for future updates.

The app is suitable for a multitude of ages and there is something for everyone. The ease of the navigation and high quality photographs make it a joy to use. Many educational applications can be very structured and subject orientated; this app celebrates the art of ‘Explore and Learn’.

Universal Zoom is a great application that is pleasing to the eye and engaging. This application has lots of educational value and comes highly recommended by the EducationalAppStore.com
