Onyx blocks the apps and websites you choose, right now or on a schedule. One focus app that does its job properly, for a fraction of what the big names charge.
iPhone · iOS 17+ · runs entirely on your phone

No bloat, no gimmicks. Just the focus tools that work, designed to feel calm.
Pick your apps and sites, pick a duration, and they’re gone until the timer runs out. Set your own time, or go strict with Monk mode, which removes the stop button entirely.

Workday, night, weekend, or hours you pick yourself. Onyx shields your apps during those windows every week, automatically, even when the app is closed.

Apps blocked while you work, freed on your breaks. Pick your focus and break lengths and the number of rounds. The switches happen on time, hands-free.

Most focus apps want an account and a subscription to a server somewhere. Onyx wants neither.
No sign-up, no email, no login. Open it and go.
Everything runs on your iPhone. Nothing leaves it, because there’s nowhere for it to go.
No analytics, no ads, no profile of your habits. It’s a tool, not a funnel.
Start with a free week. Then keep it for less than the others charge in a month.
The whole app, no commitment.
