Can I Merge Multiple Recordings in the Same Day?

Yes, if both were at the same record, you can!

If you are recording via your iPhone, when you go to save the second half of your day, Slopes will detect the original recording and ask if you'd like to merge the two activities.

If you recorded via your Apple Watch, you can still get Slopes to offer to merge them. Head to either recording from that day, and then hit the edit button in the top right. Slopes will prompt asking if you'd like to merge them.
