Not a to-do app. A starter. OneNext is built for getting started, not managing endless lists. When your to-do list grows, choosing what to do first can freeze you. OneNext removes the noise and guides you to one small next step. What OneNext does • One Next Step: Only one item on screen—no overwhelming lists. • Done / Later: Two choices to reduce friction. • AI “first step” breakdown: Turns vague tasks into a clear 5-minute action. Internet connection required for AI breakdown. • Make it smaller: Break it down again when it feels hard. • Keep your wins: Track what you did, not what you didn’t. Just one next step. Start small. Keep moving.

The task is big. Your first step doesn’t have to be. Just Start helps you begin the task you keep putting off. Describe what feels hard to start, find one small action, and take it into a short focus session. MAKE THE FIRST STEP SMALLER Ask the app’s AI for a concrete first step for your own task. Still feels like too much? Ask for a smaller action. If AI is unavailable, you can write your own step or use the timer directly. START WITH TWO OR FIVE MINUTES Begin a short session without answering a survey. Pause when you need to. Longer focus and break presets are available when you want more time. SUPPORT WHEN YOU WANT IT Choose visual timers and ambient sounds. Pro adds more sound options, mixing, and optional AI check-ins. These check-ins are automated messages, not a live person working beside you. KEEP A LITTLE MOMENTUM See your focus history and progress. Return to a recent task or use a routine for something you do regularly. Optional account sync is available; an account is not required to start. START FREE The free app includes up to three focus sessions and three AI task requests per day, core progress tools, and three ambient sounds. Pro adds unlimited focus sessions and expanded support. AI requires internet access and is subject to service limits. PRIVACY The timer and local progress work offline.
