How did I feel at the beginning? A moment of joy, an uneasy feeling, something left unsaid. HeldLine: Boundary connects these moments into a journal you can return to as your feelings change. START WITH A FEW WORDS Choose an emotion label and add a short note. You do not need a polished diary entry. You can keep journaling entirely in your own words, without AI. KEEP YOUR FIRST FEELING Connect later experiences and changes to the original note. A chronological tree lets you revisit how you felt then without replacing it with how you feel now. TURN CONVERSATIONS INTO REFLECTIONS Optional AI chat suggests emotion labels and short notes from what you share. You can change the labels yourself. AI interpretations are suggestions, not diagnoses or verdicts. FIND WORDS FOR A REPLY When you want to decline or ask for time, create a draft from your situation or conversation. Edit it and copy it when ready. RETURN AT YOUR OWN PACE Weekly reflections and optional reminders help you revisit your notes. Check the next reminder and send a test notification in Settings. Use Boundary to write about relationships, notice what triggers anger, or keep track of feelings and thoughts while learning about cognitive behavioral therapy. It does not provide treatment, diagnosis or professional advice. FREE JOURNALING AND AI CREDITS Manual notes, follow-ups, reading your history and on-device weekly reflections are free.

Verdict
The clearest difference is in-app purchases: Positive Mind at none against Boundary's 10. Positive Mind also leads on device support (3 vs 1) and iOS requirement (12.0 vs 17.0). Boundary's advantage is ads (none vs shown). On price there is nothing between them.
