Starting is the hardest part. Gentle Start makes it one tap. When a task feels too big to begin, this is the smallest possible push. Open the app, tap once, and a calm focus timer counts up from zero. That's it - you've started, and starting was the whole battle. There's no goal to reach. No streak to keep alive. No countdown racing you to a finish line. Gentle Start counts UP, not down - so there's nothing to fail and no way to fall behind. Stay thirty seconds or thirty minutes. Both count. Both are real. HOW IT WORKS - Tap to begin: one button, no setup, no plan, no account. - The timer counts up quietly inside a living, animated scene. Nothing on screen pressures you - it's just proof that you're doing it. - Stop whenever it feels right. You showed up, and that's enough. WHY IT'S DIFFERENT Most focus timers and productivity apps are built around finishing - streaks, daily goals, charts, pomodoro countdowns, reminders that nag. For a brain that already feels behind, that pressure is the very thing that makes starting feel impossible. So Gentle Start leaves it out. No metrics staring back at you. No guilt. No catching up. Just a gentle way across the one line that actually matters: from not-started to started. WHO IT'S FOR Made for procrastinators, people with ADHD and executive dysfunction, students facing down an assignment or a long study session, writers staring at a blank page, and anyone who knows the strange, heavy weight of simply beginning. Whether you call it procrastination, task paralysis, or "I just can't start" - if "just start" has never once worked as advice, this was built for you. CALM BY DESIGN - 28 living themes: drifting clouds, falling snow, rising bubbles, a quiet night sky, and more - soft animated scenes that are easy on the eyes while you work. Or pick random and come back to a fresh space each session. - Ambient soundscapes: rain, fireplace, forest, and other gentle audio to ease you into focus. - A companion while you work: a tiny animated sun keeps you company in the Dynamic Island and on your Lock Screen during a session - with a whole sky of suns to choose from. - Home Screen widgets and Live Activities keep your session calm and glanceable without opening the app. - Works with Siri and the Action Button, so you can start without even looking. WHAT GENTLE START WILL NEVER DO - No streaks - No daily goals - No guilt, no shame - No ads - No subscriptions - No account or sign-up - No tracking Your sessions stay on your device. There's nothing to log into, and nothing watching you work. Gentle Start isn't here to make you do more. It's here to make starting feel possible, especially on the days it doesn't. Tap once. Start small. That counts. Gentle Start is on iPhone, iPad, and Apple Watch. Wherever you are, make your next start a gentle one.
