Threadline: Dating Journal
Private Relationship Journal
Only for iPhone
Free · In‑App Purchases
iPhone
Remember meaningful moments, keep private details close, and notice patterns in your own experience—without accounts, public profiles, or people rankings.
Threadline is a private relationship journal for remembering the people, dates, conversations, and moments that matter to you.
Create a personal profile for someone you’re getting to know. Keep a timeline of dates and conversations. Save places, time spent together, milestones, expenses in the currencies you choose, and the details you want to remember next time.
REFLECT YOUR WAY
Choose from thoughtful prompts or create your own metrics. Record how you felt, whether communication felt easy, what gave you energy, or anything else that matters to you. Threadline keeps each metric separate. It does not rank people or tell you who is “best.”
PREPARE WITH A PRIVATE BRIEF
Before your next date, quickly revisit the last interaction, pinned details, open questions, current relationship stage, and recent rhythm. Your brief is built locally from information you chose to save.
NOTICE PATTERNS, NOT VERDICTS
Explore clear, local statistics about interaction rhythm, time together, personal reflections, tags, stages, and spending by currency. Every insight shows its date range and sample size. There are no compatibility verdicts, diagnoses, or relationship decisions.

Threadline is a private journal and personal organization tool. It is not a dating, matching, messaging, surveillance, medical, or therapy service.
Some features require Threadline Pro. Available plans and prices are shown in the app before purchase. Annual subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in your App Store account settings. A one-time Lifetime option is also available.
Readable JSON/CSV exports are plaintext. Password-encrypted backups can be verified and restored; restore replaces the destination journal and is not automatic sync. Photo attachments are not included. Restoring an App Store purchase restores Pro access only, not journal content.
