Dashcam video editing

Hi guys,
Looking for some recommendation for dash cam video editing.
I got a front and rear dashcam and it records a clip for front and back separately.
is there any software/apps, ideally free, you guys use to join them so they are side by side or on top of each other while maintaining the correct time line. Showing things like speed, gps etc would be a bonus.
cheers
