About

OneNext

Features
Read full description

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.
