CLUSTER FLASHCARD-MATH-ADDITION · 13 ENTRIES · EARLIEST ENTRY 2009-02-20
Arithmetic flashcard practice apps
This cluster comprises flashcard and drill apps for practicing basic arithmetic (addition, subtraction, multiplication, and division) with features such as timed quizzes, configurable number ranges, and progress tracking. Entries span from February 2009 to June 2026, with a notable gap between 2018 and 2024, making the timeline sporadic rather than steadily growing. Traction leaders, based on activity signal, are Flash Cards: Math Facts, FlashCards — Say & Flip, and Cool Math Flash Cards, all showing zero stars but ranking highest relative to others.
Entry timeline
ENTRY TIMELINE
Each bar is the month a 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 a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
