Blueprints you've configured in Zoho CRM can be executed directly from the mobile app, so a sales rep out on a field visit can progress a Deal through its process without needing to be at a desktop.
If a Blueprint transition requires certain fields or a note before it can be completed, for example entering a discount within set parameters and logging the details as a note before moving from Qualification to Negotiation, those requirements can be fulfilled directly from the mobile app when executing that transition.
If you use Client Script to add custom logic to a Blueprint transition, such as showing a non-mandatory field pop-up before a transition, be aware that Client Script support for Blueprints on mobile apps has lagged behind the web version, so test any Client Script-dependent transition on mobile specifically before relying on it in the field.
