Three Things

Too many tasks. Too little focus. Sound familiar? Three Things is a minimalist daily planner that limits you to just 3 tasks per day. No endless to-do lists. No overwhelm. Just the 3 things that actually matter today. Unlike traditional task managers and productivity apps, Three Things uses intentional constraint to create focus. You pick your 3 priorities each morning, check them off, and build momentum through daily streaks. Why people switch from complex to-do apps: Clarity over chaos — know exactly what matters today instead of scrolling through 50 tasks. Daily streaks and completion tracking keep you consistent without pressure. A 30-second morning routine replaces complicated planning systems. All data stays on your device — no account, no cloud, no tracking. Three Things is the best daily planner for people who are overwhelmed by Todoist, Things 3, or TickTick and want something radically simpler. It works for ADHD focus, daily habit building, goal setting, and anyone who needs fewer choices to get more done. What makes Three Things different from other to-do list apps: Most productivity apps give you unlimited tasks, projects, tags, and filters. That flexibility becomes the problem. Three Things removes the decision fatigue by giving you exactly 3 slots. No categories. No sub-tasks. No priority levels. Just today's 3 most important things. This approach is based on the proven productivity principle that forcing prioritization leads to better output than managing longer lists. When you can only pick 3, you have to choose what actually matters. Built for people who want less, not more: Entrepreneurs and freelancers who need daily clarity without project management overhead. Students managing coursework, study sessions, and deadlines without complex systems. People with ADHD or executive function challenges who benefit from reduced choices. Anyone recovering from productivity app burnout who wants to actually finish things instead of organizing them. Remote workers who need a simple daily focus tool without team features they will never use. Track your progress over time: See your completion rate and daily streaks. Review your timeline of finished tasks. Get insights into your most productive days and patterns. Watch small daily wins compound into real progress over weeks and months. Privacy first — your data stays on your device. No sign-up required. No social features. No data collection. Just a clean, distraction-free planner that opens in seconds and helps you move forward every day. Stop managing tasks. Start finishing them.

Verdict
The clearest difference is in-app purchases: Deep Hours at none against Three Things's 1. Deep Hours also leads on update cadence (daily vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
