About
Practical tools for everyday life with ADHD. Lucid Zen brings together app blocking, guided breathing, notes, an emotional compass and a visual N-back game.
LIMIT DISTRACTIONS
Block selected apps immediately or schedule your blocking sessions. With Auto Block, alternate estimated usage time and breaks.
TAKE A MOMENT FOR YOURSELF
Explore how you feel with the emotional compass, take a guided breathing break and write down ideas you want to come back to.
EXPLORE THE N-BACK GAME
Watch positions and colours, then spot matches with earlier steps. Adjust the level and speed at your own pace.
FREE, WITH NO SUBSCRIPTION
All features are free. In-app purchases are optional contributions to support development. No account required. Your notes and history are stored locally on your iPhone.
MEET THE COMMUNITY
Find our French-speaking community on Instagram: @lucid.tdah. Share experiences and ideas about everyday life with ADHD.
Lucid Zen requires iOS 17.4 or later. App blocking requires Screen Time authorisation. Auto Block uses estimates: blocking and unblocking may be delayed.
Lucid Zen is an everyday wellbeing tool. It does not diagnose or treat ADHD and does not replace professional support.
