Myk supports HERO3-7, and Session. We do our best to test and support the Hero3 and Hero4 ongoing, but functionality may eventually be limited and a bit unpredictable as GoPro no longer officially supports Hero4 and below. Since our functionality is dependent on the GoPro SDK and firmware, we are forced to adapt. We continually do our best to support Hero3 and Hero4 as long as we can.
Myk currently does not support the HERO8. We hope to support in late December 2019.
