About this app

One new word every day, on your home screen, without opening an app.

Hapax has no ads. No account. No subscription. No notifications. No tracking. The Data safety section says no data collected because there is nothing to collect. The whole app works offline. There is no server to talk to.

• 440 hand-curated words across four difficulty levels, from foundation to expert
• A home screen widget that actually shows the word, its definition and an example sentence, not just a headline
• Put the word on your lock screen too, if you want it. Hapax can set your lock screen wallpaper to today's word and change it every midnight. It is off until you turn it on, it touches the lock screen only, and your home wallpaper is never changed
• Tap the pronunciation to hear it, even in airplane mode
• Nine themes: colored papers for daylight, deep velvets for night. The widget wears them too
• Your complete history, forever, not just the last five words
• Practice the words you have already met, ten at a time. No streaks, no scores, no guilt
• Nothing is gamified. Nothing nags. Nothing is behind a paywall.

Made for people who love words: writers, readers, lawyers, students, and anyone who wants a bigger vocabulary without a bigger screen-time number.

A "hapax" is a word that appears exactly once in a text, which is how often you will see each word here: once, at its moment, remembered.
Word of the day on your home screen. No ads, no account, no subscription.
