VerbOS Routine

verbOS helps you actually absorb new words — not just look them up and forget them. Add a word, see a real definition, apply it in a sentence you write yourself, and let daily and weekly summaries pull it into your everyday vocabulary.

HOW IT WORKS • Add a word and look up its definition, part of speech, phonetic pronunciation, and example sentence — free, no account needed. • Apply it by writing a real sentence with it. This is the step that makes it stick. • Mastery is earned two ways: use a word in your own sentences 5+ times across 3+ different days, or correctly pick it out of 3+ different sentences in the Quiz. Either is real evidence you know it. • Daily streaks and a weekly summary (with charts) show your progress.

SMART, PRIVATE AI — ON BY DEFAULT, NEVER REQUIRED verbOS defaults to Apple's own on-device Apple Intelligence for richer definitions, sentence feedback, and quiz generation — completely private, instant, and free, with nothing ever sent to a server. If your device doesn't support it, connect your own Claude, ChatGPT, or Gemini account instead — your key stays on your device. Every feature also works with no AI configured at all.

VOICE AND CAMERA Dictate your practice sentences instead of typing, with live on-device speech recognition that keeps listening right through natural pauses. Read-aloud buttons throughout the app use the system voice. On supported devices, scan a word straight off a printed page with your camera instead of typing it in.

KNOW HOW RARE A WORD REALLY IS Every word gets a rarity score from a real, offline word-frequency dataset — see instantly whether a word is Everyday, Uncommon, or genuinely Rare. Your Vocabulary Prestige Score rewards words you've actually mastered, weighted by rarity — not just words sitting unused in your list — and you can share it as a card with friends.

SYNCS PRIVATELY ACROSS YOUR DEVICES Your word list syncs through your own private iCloud account across your iPhone and iPad — nobody else can see it, and there's no account to set up. A home screen widget shows today's focus words at a glance.

BUILT FOR IPHONE, IPAD, AND MAC A genuine iPad and Mac experience with a sidebar layout, not just a stretched iPhone screen — add a word, look it up, and apply it in a sentence from whichever device is in front of you, kept in sync.

PRIVACY, PLAIN AND SIMPLE No account, no login, no analytics, no ads, no tracking. Your words live on your device and in your own iCloud. See our full privacy policy for details.
