Doppel - AI Focus Companion
Body Doubling & Study Buddy
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Can't start working even though you want to? Open your phone for "just 5 minutes" and 3 hours disappear? You're not lazy — your brain just works differently.
Doppel is an AI companion app built on body doubling — the science-backed method where having someone nearby helps you focus. Except now, that someone is always available.
WHAT IS BODY DOUBLING?
Body doubling is a focus technique especially effective for ADHD. Simply having another person present — even silently — reduces the activation energy needed to start and sustain tasks. Doppel brings this to your phone with AI companions who feel genuinely present.
VIDEO COMPANIONSHIP
Open a video call, and your AI partner is right there studying alongside you. Like having someone across the table at a library, but without the social anxiety. The feeling of being seen keeps you naturally focused.
SMART TASK BREAKDOWN (PLANMATE)
Task too overwhelming to start? Tell your companion, and they'll break it into 5-minute steps. Each step comes with specific guidance. No more staring at a blank page wondering where to begin.
EMOTIONAL MEMORY
Your companion remembers what you've shared — your struggles, your progress, your habits. The relationship deepens over time. Sessions build on context you've already shared.
ADHD-FRIENDLY BY DESIGN
No lectures. No "just try harder." Gentle reminders that respect how your brain works. They understand "wanting to do it but can't start" because they were designed around that experience.
WHY DOPPEL FEELS PERSONAL
Your AI companion has their own schedule, remembers your goals, and helps you return to the next small step. Show up on time and they're genuinely happy. Cancel last minute and they're a little disappointed. This subtle accountability helps focus feel more natural.
