Duodisly is a web-based shared accountability service for couples and families. It helps people follow through on agreed tasks by making progress visible and adding a collaborative review process. Members create a task, assign who will do it, submit the result, and have another person approve it or request changes. Approved tasks earn points according to their difficulty, which can then be spent on personal or shared rewards chosen together.

Duodisly offers two types of private spaces. Couple is designed for two equal adults who can create tasks and rewards, complete tasks, and review each other’s results. Family supports up to two adults and four child profiles; adults manage access and guide or approve tasks, while children can suggest task and reward ideas. Features include recurring tasks, optional photos, files or comments as evidence, review explanations, and an activity history. The service works in a web browser on computers, tablets, and phones, with Android and iOS apps listed as coming soon.
