# Zenku > A mindfulness app built around AI-generated haiku and guided breathing. > The 5–7–5 haiku structure mirrors a breathing cycle: inhale (5), hold (7), exhale (5). Zenku generates personalised haiku based on the user's current mood, emotional tone, and chosen theme — then pairs it with a guided breathing session. It is designed for people who want moments of calm without the commitment of a formal meditation practice. ## Zengram Zengram (zengram.zenku.life) is a free daily word puzzle connected to Zenku. Players drag across touching letters to trace hidden words on a grid. Each word found uncovers part of a haiku inspired by something positive happening in the world. A new hand-reviewed puzzle is published every morning. Log in to save your streak. ## App Zenku is available free on Android. An iOS app is in development; users can join the waitlist at zengram.zenku.life/app. ## Links - [Homepage](https://zenku.life/) - [Zengram daily puzzle](https://zengram.zenku.life/) - [Get the app — Android now, iOS coming](https://zengram.zenku.life/app) - [Privacy policy](https://zenku.life/privacy-policy.html)
