Count boundary: the card and blog counts describe the public website on August 22, 2026. They are not a guaranteed count of the live in-app inventory. Curio does not currently publish a category count because older marketing copy and the current app taxonomy disagree.

First-party assets

These are product assets, not press logos or evidence of coverage. For a publication-specific format or usage question, email support@trycurio.app.

Useful reporting angles

These are documented story directions, not claims that a publication has covered Curio.

Keep the gesture, change the payload

Why a reading app kept the full-screen swipe instead of asking people to abandon the feed interface entirely.

One founder, four languages

How a solo developer owns the app, API, content systems, and distribution while reading the product in the four languages he speaks.

Publishing the source gaps

Why Curio reports both the sourced and unsourced public card counts instead of treating every card as equally evidenced.

The work is in refusal

What a short-form content system must reject, label, or route to review before it feels like a reading product rather than infinite filler.

Press and creator inquiries

Ask for a product walkthrough, current screenshots, technical background, or a factual correction. Independent criticism is welcome; Curio does not require positive coverage.
