About

TwentyFiveWords

Twenty Five Words is a calm daily-writing companion built around small, finishable sessions—not marathon desk sessions. You get a fresh creative challenge each day (or write freely when you want), hit twenty-five words to stay on streak, and keep everything in a private Stories archive you can tag and revisit anytime. Three challenges per day: Browse carousel-style cards, pick what resonates, then open full-screen detail—prompts rotate so practice stays varied. Craft-aware prompts: Many exercises include short technique notes—style study, emotion practice, dialogue, and more—without feeling like homework. Write freely: Toggle off the prompt when you’d rather journal or riff on your own idea; title, tags, and streak-friendly word count stay consistent. Stories archive: Every submission lands in Stories—filter by hierarchical tags, scroll by month, edit entries later, and copy text whenever you need it elsewhere. Progress & streaks: Current streak, stats, and a Duolingo-inspired calendar keep momentum visible—without turning creativity into a score chase. Widgets & reminders: Glance at streak status from the Lock Screen or Home Screen so gentle accountability stays peripheral, not loud. Private by default: Writing stays on your device; optional iCloud sync uses Apple’s private CloudKit container—we never host your journal. Thanks for being one of the first writers here, TwentyFiveWord will keep improving with every update.
