Clusters

Every group of products the index has found building the same thing. Biggest collisions first, or newest first — all 10,148 of them, 50 to a page.

  1. Mobile document scanning apps8 entriesfirst seen 2021-12-23This cluster consists of mobile apps that scan documents, receipts, and notes, converting them to PDF or editable text via OCR, with features like batch scanning and folder organization. Six dated entries appear before the index start, scattered from July 2013 to July 2026, showing a thin and irregular history with no clear growth pattern. The three traction leaders—dastavault, Document Scanner | Scan to PDF, and Archiv—all show zero stars, indicating minimal user engagement. Given the sparse and uneven timeline, the cluster's dated history is too thin to read a meaningful shape from.
  2. Emotional intelligence training apps8 entriesfirst seen 2021-11-30This cluster comprises apps that teach emotional intelligence and anger management through guided exercises, short daily sessions, and structured feedback. With only two dated entries before the index start and several members lacking source dates, the cluster's dated history is too thin to read a shape from. All traction leaders—ember-anger, Ahead: Emotional Intelligence, and ankerup-app—show zero stars, so no clear activity leader is evident.

How to read this list

HOW TO READ THIS

A cluster is a group of products whose descriptions sit close together, redrawn from scratch every night. Groups split, merge and disappear between rebuilds, and a group's size can change without a single product changing. Read this as a map of where ideas crowd, not a census — most products sit in no cluster at all.

Many labels here are auto-generated from the group's own text rather than written, and the summaries and gap analyses lag behind the clustering: the pass that writes them has not caught up with the groups the last rebuild created. A missing summary means we have not written one, not that there is nothing to say.

“First seen” is the earliest date any member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so an early date reports how far back a member's own source dated it — not how long we have been watching. The Pulse carries the live totals.
