About this app
Risky Business App is a risk management tool for projects, made by independent developer Ricardo Martinez for Mac, iPad and iPhone. It is aimed at project managers and teams who need to capture risks, rate them by probability and impact, and follow them through to mitigation without setting up a heavyweight enterprise system. Risks can be entered from templates and are scored and prioritised automatically, then shown on a 5x5 risk matrix alongside a dashboard, portfolio view, timeline, measures overview and reports. Data stays on the device by default, with optional iCloud sharing with named people, per-person read or write access and optional passphrase encryption of the database. Recent versions added optional AI suggestions for rating a new risk using your own AI provider, links between risks with a network view, cost tracking per measure, recording of losses when a risk occurs, and creating risks from a photo or scan of minutes or a whiteboard, with text recognition done on the device. The developer has written two blog posts about adapting the app for iPhone Duo, describing a navigation rethought for the device and a series of space-saving changes for the folded screen. The app is free with no in-app purchases, according to the developer's website and the App Store listing.

How it uses iPhone Duo
In a blog post dated 4 October 2026, the developer says the app picks its layout by available width: a compact iPhone interface when the iPhone Duo is folded, and overview and detail side by side when unfolded. A vertical bar along the right edge holds the main sections when folded and the current section's tools when unfolded. If a form or dialog is open when you fold or unfold, the app keeps its current shape until you close it. A later post on version 2.14 describes a reworked risk matrix and three-line register rows for the folded Duo. DuoDiscover has not yet tested it on an iPhone Duo.
