There are a few apps that help visualize Service Design projects:

1. Smaply: create customer journeys, personas and stakeholder maps

2. Custellence: create customer journeys

3. UXpressia: create customer journey maps, personas and impact maps

4. Blueprintly: create service blueprints (free but in beta)

Most of these apps are focused on:

1. the customer journey: how the service feels to the user

2. or the Service Design Blueprint of a Service: what is needed for the service to work and all the steps that the customer goes through
