About this app

Stop juggling endless lists. Focus on one task at a time.

OneTask is an ADHD app and minimalist to do list that shows you only the single most important task right now. Everything else waits its turn. No overwhelm. No guilt. Just clarity.

BUILT FOR ADHD AND NEURODIVERGENT MINDS
Long to-do lists freeze you. One clear next step gets you moving. OneTask is a simple ADHD organizer designed around executive function: fewer choices, no deadline pile-ups, no visual noise. Made for adults with ADHD, executive dysfunction, autism or just a busy brain, it helps you prioritize and actually start.

TODAY ONLY. NO FUTURE DATES.
