Stop deciding. Start doing. The hardest part of any productive day isn't the doing, it's the deciding. Modes takes that decision off your hands so you can finally get out of your own way. Here's how it works: 1. Press the Start Random Task button. 2. Get a task. 3. Do the work while it automatically time tracks for you. Here's what Modes currently has to offer, with more coming in future updates: Task Randomizer - Forget decision fatigue. Modes randomly selects your next task so you stop overthinking and start moving. It's surprisingly fun, weirdly addictive, and actually effective. Start, Stop and Pause - Life doesn't run on a perfect schedule. Pause when something comes up, resume when you're back. Every second of your day is tracked with precision. Task Stats - See exactly where your time goes. Which tasks take longest? What time of day are you sharpest? Your stats don't just inform, they change how you work. PDF Export - Print or share your to-do list in seconds. Completion History - Every finished task becomes part of a bigger picture. Modes automatically builds a record of what you've accomplished, not just today, but over time. A timeline of your actual life. There's no shortage of to-do apps. Modes is something else: a new way to work that's structured enough to keep you on track and unpredictable enough to keep you engaged.
