Avion is a real-time, collaborative user story mapping tool for agile teams.
With Avion you can:
1) Visualise your entire product and its user journeys on a user story map.
2) Effectively plan future releases and uncover gaps in your plans by identifying dependencies.
3) Focus on delivering real value to your users by prioritising the right work.
4) Easily share your release plans and product roadmap with your whole team.
I've been user story mapping for a number of years. Tools on the web has never been a strong point for story mapping. Avion is the best I've found so far. Personally I'm using it in conjunction with Azure Devops to manage our planning and delivery processes.
Still lacks a few things such as tagging, but I asked them team and this is planned on their upcoming roadmap.
Based on our record, Avion seems to be more popular. It has been mentiond 2 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Agree with others that outlining these details in a story's description is the way to go. Another tool for you to check out (I helped build it): Avion – Story Mapping. Source: almost 2 years ago
To give some recommendation on a non-mainstream tool: I really enjoy using avion.io for a side project right now. Source: almost 3 years ago
