Supersets and circuits
Group two exercises and it is a superset; group three or more and it is a circuit. The app counts rounds and rests between them, not between stations.
Group exercises in the split editor and they draw as one card during the session, with the active exercise open and the others listed beside it showing their weight and how many rounds they owe.
The name follows the count rather than being something you pick. Two exercises is a superset, three or more is a circuit — there is no menu asking you to label it, because the behaviour is identical either way and only the word changes.
Rounds are computed from the set counts of the members, so a group where one exercise has four sets and the rest have three runs four rounds, and the app tells you who still owes work.
Rest is the part most apps get wrong. Committing a set hands over to the next exercise that still owes a round, with no rest in between, because you are supposed to walk straight to the next station. The rest comes after the round, when everyone has been through once. Each group can carry its own two durations if the defaults do not fit.
Any two ungrouped exercises can be paired, not just neighbours in the list — the partner is moved up to join the anchor, so you do not have to reorder anything by hand first.
