TriDo vs Only Three

Your brain holds 3 things at once. Not 10. Not 50. Three. TriDo is the anti-to-do list. While every other productivity app lets you add unlimited tasks, TriDo deliberately limits you to exactly 3 per day. That constraint is the product. WHY ONLY 3 TASKS? Research from cognitive scientists like Nelson Cowan shows your working memory holds just 3 to 4 items. Every task beyond that competes for mental space, creating anxiety — not progress. The Zeigarnik Effect proves that unfinished tasks haunt your mind. A 10-item to-do list guarantees open loops at bedtime. 3 tasks can actually be finished. Every day. Productivity legends agree. Warren Buffett says "successful people say no to almost everything." James Clear writes that you fall to the level of your systems. Tim Ferriss limits himself to 2 mission-critical items. Brian Tracy's Law of Three has sold 3 million copies. TriDo turns their wisdom into a daily habit. HOW IT WORKS 1. Open TriDo. See 3 empty slots. 2. Type your 3 most important tasks. 3. Swipe right or tap to complete each one. 4. Finish all 3. Build your streak. 5. Share your wins with a beautiful card. That's it. No folders. No tags. No priorities. No integrations. Just 3 things that matter today.

TriDo mirrors the solution: radical constraint. When you can only pick 3, you're forced to choose what truly matters. 3 tasks. Every day. That's all it takes.

Most to-do lists don’t work. They capture tasks, but don't help you complete them. Only Three is different. Instead of endless tasks and cluttered lists, you choose just three things to complete each day. That’s it. Simple, focused, and effective. Clarity, not clutter. Why it works Plan your priorities the night before. No more long lists. Just the three things that actually matter. Built for focus. Feel accomplished daily. Review your History and keep across completed tasks. Finish your three tasks and end the day with a clear win. No accounts, no distractions. Your tasks stay on your device. Open the app and go. Stop planning everything. Start finishing what matters. Let's start, with Only Three.
