iOS App

1. Process

Rally Charge is an app that can work in two ways. For business, it can attract clients by offering free charging devices for the effort of signing into the app. You can customise the advertising campaign that will be shown on the mobile while charging. For individual clients, they can customize their charger to work in a simple ITTT (If This Than That) manner. Rally chargers work with simple USB plug, so they are portable, and can be used anywhere.

The app uses Android Host-Accessory feature that allows to communicate with a custom hardware device.

Ola, Android developer

"The most interesting thing about working on Rally Charge app was the integration with the custom charger. It uses Android Host-Accessory feature for communication with the hardware device, and gives great opportunities for future development and potential usages."

2. Mobile app


iOS ecosystem is known for its power efficiency and battery lifetime optimizations that limits third-party work when the app is not in the foreground. When using external accessory developer receives a great power of working in a background, but it also comes with great responsibility to not abuse user's trust and drain his/her battery. Rally Charge iOS app has a privilege to operate without any limitations but it still meets the highest resource efficiency standards in order to deliver best user experience in all possible areas.


The business has the ability to assign a charger to a specific custom advertising campaign, and show the advertisements on the user's phone while charging.

3. Admin panel

Through simple email and sms templates, you can create your own marketing campaigns. All connected to native mobile applications out of the box.

4. App redesign

Consistent Visual Communication

This project belongs to a group of apps provided by Rally which works with rally charger.

Our main goal was to make visual communication very clear and consistent, even between the apps from the group. During the redesign process, to emphasize that all those apps belong to one brand, we created style guidelines, that can be also applied in the next apps. We share essentials elements between apps, starting with icons, buttons and form looks, typography and other basic elements. By using familiar patterns we allow users to learn faster how to use the app.

For Rally charge app we have used dark background colors and light texts. The main color is vivid turquoise, which makes CTA elements standing out from the layout. We stay with a minimalist, clear design based on delicate lettering and lined up icons.
