Most apps ask how you feel. Parts asks why.
Open Parts. Pick a feeling that's loud right now — anxiety, grief, perfectionism, anger, the urge to disappear. Walk through a 5-minute guided conversation. Then receive a letter, written back from that feeling.
It's strange the first time. Powerful the third.
WHY PARTS IS DIFFERENT
Most mental health apps track your mood and call it a day. Parts is built on Internal Family Systems — one of the most-cited therapy frameworks of the last decade. The premise: you're not one mind. You're many. Every part of you has something to say. Parts gives them a voice.
HOW IT WORKS
1. Check in — pick what's showing up today
2. Explore — guided prompts walk you through it
3. Receive — a personal letter, written back from that part
4. Map — watch your inner world take shape over time
5. Share — generate a summary for your therapist
WHO IT'S FOR
— People in IFS therapy looking for structured work between sessions
— Anyone curious about parts work, inner child work, or shadow work
— Therapists looking for a journaling tool to recommend
— Anyone tired of mood trackers that don't go deep
NOT THERAPY. JUST DEEPER.
Parts isn't a therapist. It's the work you do between sessions. Or before you've started. Or instead, if you're not ready.
