Have a feature that allows users to enable an auto-reply message to text messages/phone calls that are received while the car is mobile (i.e., you're driving) that lets the contact know that you are currently driving and will get back to them.
Hi there! Although this feature is not yet available on the iPhone app, we released the Do Not Disturb feature for Android last month :) As mentioned in this FAQ, incoming calls are immediately sent to voicemail and an auto-reply text message is sent to the caller stating the following: "Hi! I’m currently driving but will get back to you later."
We're still hoping to introduce a similar feature to the iPhone app, but we'll have to wait for the appropriate iOS APIs.
