I love Tentacle

We’ve been using Tentacle for 2 years with minimal problems. For providing very basic timecode utilities, the apps pack a powerful punch.

Additional feature

The app works great. Would love a notification when tentacle box's battery runs low and when cable got unplugged from camera. Would it be possible ? Would be pretty cool

Decent results with Tentacle Sync Studio

This system works quite well in conjunction with the official Tentacle Sync Studio software for Mac OS. However, I have not been able to get accurate syncs using the audio timecode features in Premiere or Resolve.
