Parallel

Parallel is a scheduling tool for distributed teams that tracks fairness as well as availability. When a team spans continents, one member ends up on an early-morning or late-night call, and over months it is often the same person. Parallel takes everyone's time zone, working hours and hard constraints, finds the best possible schedule, and when no perfect split exists it rotates who adjusts.

You create a team, invite members and generate a multi-week rotation in one click, replacing endless chat messages or polls and manual time-zone math. It supports all IANA time zones and rotates automatically each cycle. The tool also shows who has already taken the inconvenient slot and how often, which gives managers visibility they otherwise lack, since tools that only find a meeting time do not track who has carried the burden.

Owners and members see different views of the teams and the rotation schedule. The site says you can start free, and a pricing section lists the plans, though no prices appear in the available text. It is aimed at teams that care about each other's time and want fairness to be visible rather than assumed.
