Inchworm is a calm room to start in. When you're frozen — you know what to do, you just can't begin — open Inchworm, type or say the thing, and it shrinks it into one absurdly small first step. Then a quiet five-minute session helps you start. That's the win. Designed for ADHD brains and anyone who struggles to get started: • Shrink any overwhelming task into one tiny, doable first step • A gentle count-up session — no red countdowns, no pressure • We celebrate STARTING, not finishing • Days you showed up — a streak that pauses, never breaks. No shame here. Inchworm Pro adds unlimited AI shrinks, voice input, and an accountability buddy. No punishment. No guilt. No alarms. Just a smaller first step. Designed for ADHD brains — and anyone who struggles to start. Inchworm is a wellness and productivity tool — not a medical device, and it does not diagnose, treat, or cure ADHD or any condition. If you're struggling, please talk to a professional. Terms of Use: https://getinchworm.app/terms.html Privacy Policy: https://getinchworm.app/privacy.html
