## Version history (last 5 releases)

### 1.20 — 2026-08-26

Accessibility: full VoiceOver support with labelled playback controls, Dynamic Type across every screen including the player, and offline download so the app works without a connection.

Inclusivity: localized into ten languages. Audio-first design means the product is usable by people who find sustained reading difficult, including users with dyslexia and low vision.

Uniqueness: most apps in this category compress an entire book into a summary. Knotd inverts it — one idea per session, given depth, with a streak as the unit of progress rather than a completion percentage.

New better quality content and more interactivity options

### 1.1.40 — 2026-08-01

### 1.1.38 — 2026-07-15
