Replug is a route planner for Tesla vehicles using the Tesla Supercharger network, similar to what's inside Tesla vehicles. Enter a start and destination and Replug will calculate an optimal route with any necessary charging stops along the way. You can configure options such as your vehicle model, consumption, and state of charge at various points along the trip. Besides route planning, you can also browse all Superchargers around the world inside Replug, and see relevant information such as number of stalls and charging rate at each location (powered by the Tesla Superchargers API). Replug is great for when you want to plan a trip while you're away from your vehicle or computer. Or if you are interested in owning an electric vehicle and want to learn more about doing road trips with an EV. Replug is not associated with Tesla Motors in any way.

Charge Key's advantage is update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.
