With JBV1 on Android, you do not need Waze.For red light cams you will always need WAZE , I run an I phone with V1Driver works great. I don't know about android users.
JBV1 has it's own frequently updated features for Red Light Cams, Speed Cams, Combination Cams, etc. and each type can be individually configured for alert distance, whether they are announced or only shown on screen, and speed below which they will alert.
Plus, JBV1 has the ability to mark other types of locations (that are private to the user) such as known speed traps, three user configurable types, etc. which Waze does not allow.
(Now you know.
I don't expect that V1 Driver will ever adopt these types of features; but @BagNDrag might be interested in adding these kinds of features in V1 Companion for iOS at some point.
If he did, iOS users could also use 1 app only.
