Scheduled focus sessions, or an AI that reads the moment?
Opal is a beautifully made screen-time app built around focus sessions and app blocking. WithKeel takes a different angle: tell it your goal in plain words, and it decides when to step in based on what you're actually doing.
Choose Opal if you want a polished, gamified app for scheduling focus sessions and blocking apps, especially across iPhone and Mac.
Choose WithKeel if you'd rather not manage sessions and schedules — you want something that understands your goal and intervenes only when you drift.
How they work
Opal centers on sessions and schedules: you start a focus session or set recurring ones, choose what to block, and it keeps you off those apps, with streaks and stats to keep you motivated. It's especially strong on iPhone and pleasant to use.
WithKeel centers on intent: you describe what you're working toward and what derails you, and its AI watches your screen, stepping in the moment you wander — a gentle nudge or a firm, tamper-proof stop. There's no session to remember to start and no schedule to maintain; it reads context as it happens.

Who each is for
If your distractions live mostly on your phone and you like streaks and a delightful interface, Opal is a great pick. If your distractions are on your Mac during deep work and you'd rather set intent once than manage sessions, WithKeel is built for that. If you want both phone coverage and Mac intent-based accountability, they pair well.
Opal is a mature, well-loved app with strong iPhone support. WithKeel is in early access for macOS and is Mac-first, so Opal covers more devices today. Try WithKeel's approach at withkeel.app.
