Our approach
Iron and electron.
The name says it. Iron: strong, exact, dependable. A real engine that tracks everything and never guesses. Electron: energy and motion. Just enough intelligence to move your work forward on its own.
Most apps make you choose. The powerful ones feel like work. The smart ones you can't quite trust. Flume is both. Rigorous enough to depend on. Alive enough to run itself. And always a tap away from your say-so.
What we care about
The details we obsess over.
Rigor first
A real engine runs underneath everything. The intelligence only ever suggests. The engine keeps the record.
Trust, always
Fast, because we budget for it. Your data stays on your iCloud. Nothing changes without your tap. And you can always undo.
Calm at speed
Dense when you need it. Quiet when you don't. Nothing ever gets in the way of capturing a thought.
Made for Apple
Built for iPhone, iPad, Mac, and Apple Watch. It feels right because it follows the rules you already know.
