Word Sprint: Write Your Book
Word counter & accountability
Only for iPhone
Free · In‑App Purchases
iPhone
You don't finish a book in a weekend. You finish it 500 words at a time.
Word Sprint gives you one clear number each day: how many words it takes to finish your book by your deadline. Write them, log them, keep the streak alive. Miss a day and the math quietly adjusts — no guilt trip, just a new number tomorrow. Write extra and you'll watch tomorrow's number shrink while you log.
THE DAILY HABIT
Set a word goal and a deadline. Word Sprint works out today's target, tracks your pace against the finish line, and counts the days you show up. Planned rest days never break a streak. Take Sundays off. The app knows.
WRITING SPRINTS
Pick 10, 15, 30 minutes, or your own. Write until it rings. The countdown sits in the Dynamic Island while your phone is locked, and the alarm is one of ten little melodies — soft piano, guitar, celesta — that ring until you stop them. No jarring buzzers.
YOUR WRITING CIRCLE
Invite a friend who's writing their own book. You see each other show up: goal hits, streaks, milestones. Never each other's word counts, never each other's writing. Send a cheer when they have a good day. Or challenge them to a write-off — same minutes on the clock, most words wins, loser buys the coffee. Invite-only, pen names only, and entirely optional.
WATCH IT ADD UP
A heatmap fills in as the months pass. A calendar keeps every day's words and notes. Milestones land with confetti at 1,000 words, 10,000, halfway, and the day you type "The End." Badges, share cards, and a Year in Words when December comes.
MAKE IT YOURS
One book free, or a whole shelf with Premium. Covers you design yourself, with palettes, artwork, or a photo. Widgets for the Home and Lock Screen. Light or dark, whichever hours you keep.
Writing 50,000 words in November? The deadline math was made for months like that. (Word Sprint isn't affiliated with any writing organization or challenge — it's just built for the same goal.)
PRIVATE BY DEFAULT
Your writing lives on your device. No account required, no ads, no tracking. The circle is free; Premium adds cloud sync with Sign in with Apple so your books follow you to a new phone.
Premium is a monthly or yearly auto-renewing subscription, managed through your App Store account. The free plan includes three books, every habit feature, and no time limit.
