BATTERY USE Arc is only awake and using GPS when you are active and moving. For the rest of the day Arc stays in a low power sleep mode, with GPS turned off, to conserve battery. On a typical day of two to three hours of travel a single full battery charge should last from morning to evening without requiring extra recharging during the day. However longer trips (for example a long hike or cross country drive) may consume more than expected battery, due to Arc needing to be awake and recording, with GPS activated, for the duration of the trip. For longer trips, I recommend plugging your phone into a car charger or battery pack, to avoid unpleasant battery surprises. SUBSCRIPTIONS AND PURCHASES A free trial, active subscription, or Lifetime purchase is required to use the app. ## Subscription Details Your subscription will be charged to your iTunes account. At the end of the term your subscription will automatically renew in your iTunes account.
