Stack Productivity
Organize thoughts into action
Free · Designed for iPad
Stack is a thought organiser that lets you quickly jot down ideas and sort them.
A modern take on notebooks. Designed for clarity. Built for the way your mind works.
Stack is a modern thought organizer designed to help you capture ideas the moment they strike — and bring order to the chaos later. It’s more than notes or to-dos. It’s the first step to shaping your reality. A tool for taking thoughts from the immaterial world and placing it into the physical one.
- Jot things down, instantly
Whether it’s a reminder, principles, reflections, tasks, ideas, or random thoughts — drop a thread of thought into stack. Add just a title or expand with detail when you're ready.
- Sort your mind, your way
Group your Threads into Stacks (like notebooks), and break those into Branches (like sections or topics). Add Labels and colours to organise how you think, not how software wants you to.
- Designed for clarity
With a clean, intuitive interface and thoughtful visual design, Stack helps you focus on what matters. No clutter. No pressure. Just space to think clearly and act intentionally.
- Real use, real life
Use Stack to:
Plan life
Track personal projects and creative ideas
Keep a journal of thoughts and reflections
Break down goals or routines
Collect inspirations, quotes, or daily reminders
Whether you're meal-planning or mind-mapping, Stack adapts to your life.
- Make it yours
Choose from light and dark themes (More coming soon). Pick fonts that suit your vibe. It’s your mental workspace.
- What’s coming soon
We’re building AI features to help break down your bigger thoughts into smaller actions, detect urgency, and help you stay on track — all without taking control away from you. We're designing and developing more tools to help you process and shape reality, we'll Stack them on when the time comes!
