Most productivity apps act as filing cabinets for your guilt, encouraging you to organize tasks instead of doing them. SingleTasking is an 'anti-todo list' that refuses to let you multitask. You enter exactly one task, commit to it, and all other UI fades away until you finish. No backlogs, no tags, no noise. It includes a 5-second meditative breathing cycle upon completion to reset your mental RAM before your next task. 100% free, no ads, and no logins required.
