How many hours do you spend on the duty roster every month? Touchoku takes over the whole job — collecting requests, generating a fair schedule, and handling swaps after it's finalized. Built by a practicing physician, born from real hospital pain. WHO IT'S FOR - You're the one stuck making the on-call / duty roster for your department or ward - Requests arrive scattered across chat, paper, and hallway conversations - You want to end the "why do I always get weekends?" and "their pay is higher" complaints - Every swap after finalizing means rebuilding the table by hand KEY FEATURES Collect requests Create a room and share the PIN — that's it. Members enter preferred days, must-avoid days, and other work from their own phones. For people without an account, add them as proxy participants and enter on their behalf. Automatic scheduling Weekly and monthly limits, minimum spacing between duties, and no-pair rules ("these two can't share a slot") are all respected. Optional weekday day shifts, with automatic holiday detection for Japan, the US, China, and Spain. Fairness you can defend Not just balanced counts — the pay gap (max minus min) is optimized too. Set amounts per day type, in yen, dollars, euros, or yuan. Safe swaps after finalizing Simulate a swap first and see exactly how counts and pay change before applying it. Full history is kept.
