Life has plot twists.
Capture the coincidences, bizarre timing, recurring numbers, and callbacks worth remembering.
Field notes
Echo Math.
Explore similarities without assigning certainty. Every score is explainable and adjustable.
Scores rank shared tags, repeated numbers, explicit callbacks and close timing. They are not odds, predictions or evidence of a hidden mechanism.

Your data. Your rules.
Set how Echo Math compares observations, and keep a copy of your archive.
Echo Math scoring
Editable point weights. Zero disables a factor. Time proximity alone will never create a match.
Portability & backup
Download a JSON backup of your notes. Import creates new notes to avoid overwriting existing work; imported callback links are not yet restored.
Delete your account
Permanently remove your login and all journal entries from the active database. Export a backup first if you want to keep your records.
Privacy model
Each entry is scoped to your signed-in account on the server. No public profiles or shared timelines. Passwords are hashed using Argon2id, sessions are stored as hashes, and production cookies require HTTPS.
