FREE TIER: WHAT YOU GET • One curated, surprising fact every day • Real sources—every idea links to scholarship, journalism, or primary documents • Rate each idea and track your streak • No feed. No scroll. No algorithm. PRO TIER: IDEAADDICTION PRO ($4.99, one-time) Unlimited ideas. Full archive. Feed whenever you want. IdeaAddiction is for people who already consume podcasts, Substacks, and Wikipedia rabbit holes—but want it concentrated, curated, and ritualized. People who quote things at parties. People who send screenshots to group chats. Feed your brain.

Verdict
The clearest difference is in-app purchases: Circuitry at none against IdeaAddiction's 1. Circuitry also leads on ratings volume (291 vs 1) and iOS requirement (15.6 vs 17.6). IdeaAddiction's advantage is update cadence (every 3 weeks vs every 46 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. IdeaAddiction sells 1 one-off in-app purchase. Circuitry asks for nothing beyond the download.
IdeaAddiction holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Circuitry has 291 ratings behind it against 1, so its average is the more settled of the two.
Circuitry ships an update every 46 months, IdeaAddiction every 3 weeks. The most recent releases landed on October 24, 2026 and October 17, 2026 respectively.
