Hopper is an app built specifically for efficient deliveries.
The app uses readily available technology to assist TaskRabbits with the travelling salesman problem. Instead of sending deliveries down individually to our pool of on-duty TaskRabbits, they're given as bundles containing 2-8 sets of pickups and dropoffs. The app gives TaskRabbits a visual overview of their bundle, lets them reorder their route for efficiency, then the app smoothly leads them from stop to stop.
Also designed for Android.
