Pattern detection highlights post-honeymoon shifts and recurring red flags before you rationalize them away.
Private by design. No sharing, no ads, no AI training on your entries. GDPR-compliant.
Frequently asked questions
Is this a tool to label my partner?
No. Flag Tracker is a personal reflection tool. The goal is to help you see your own experience clearly over time, not to diagnose anyone.
How is it different from a notes app?
Each flag is a research-backed indicator with a category and intensity scale. The app aggregates these into trends, ratios, dealbreaker alerts and pattern-detection signals you would not see in plain notes.
Can I track more than one relationship?
Yes. You can track multiple partners under acronyms and compare them side by side.
