There are about six different companies serving DC with scooters (and one with electric bikes). Prices range from 15c a minute (jump) to a dollar to start then ten cents every subsequent minute. Rather than downloading each individual app for them, what I reccomend is an app called transit: https://transitapp.com/ It shows every scooter/bike in the area. Thumb/click one and it'll open or download the necessary app for it. It also shows all nearby buses and trains, with arrival times. You can also use it like google maps to plan trips or to show any of that information for a location elsewhere.
