QUATTRO — Four tiny tools, one window - AI answers, tasks and calendar without leaving your flow

by•
Quattro is four tiny tools in one quiet Mac window. Ask anything. Track tasks. Check your calendar. Capture a thought. All without leaving your work. What. Next. When. Dump. Four tools. Four letters. Built by a 60-year-old retired Australian Air Force veteran teaching himself to code. His first app. Native SwiftUI. No tracking. No Electron. $4.99/mo. 7 days free.

Hey everyone — I'm Darren, the solo developer behind What? I spent 20+ years in the Royal Australian Air Force, including a deployment to the Iraq War. I retired at 60 and taught myself to code. No bootcamp, no CS degree, just documentation and stubbornness. This is my first app. The problem I kept hitting: every AI tool breaks your flow. You switch windows, lose your train of thought, then spend 30 seconds getting back on track. Multiply that by 20 times a day. What? lives in a quiet sidebar — hotkey to open, ask your question, get a sharp answer, close it. Tasks, calendar and quick capture in the same window. Never leaves your flow. Built entirely in native SwiftUI. 2.4 MB. No tracking, no ads, no Electron. Happy to answer anything — brutal feedback welcome.
