Duffy provides quick access to your step count directly on your Apple Watch face as a complication. I was surprised to find that a steps complication wasn’t included on Apple Watches out of the box. Being a veteran iOS developer, I decided to build one in my spare time. I really loved my prototype version and thought there were more people who would love it too. So I put in the extra effort to release it to the App Store for everyone! Duffy is completely free, has no ads, and is even open source so if you’re also a developer, you can help me enhance it. Duffy is a simple app, but it will probably turn into the most used app on your Apple Watch. No more opening the Activity app and scrolling around to find your steps. It’s now available at a glance. Duffy is more than just an elegant Apple Watch complication. Use the full watch app for easy access to your steps, flights climbed and distance travelled for today and the past week. Set a daily steps goal and be notified on your watch when you reach it. The companion iPhone app provides the same access to your steps, flights and distance on a much larger, easier-to-read surface while also allowing you to dig deeper into your data to see trends and statistics over time. Duffy reads the steps, flights climbed, distance travelled, and activity energy from your iPhone and Apple Watch from the Health app (via the HealthKit API).

APPLE WORKOUTS TRACKS YOUR ACTIVITY. NUDGE KEEPS YOU MOVING. Nudge is the Apple Watch companion that turns your daily step goal into a simple countdown. See exactly how many steps you have left, how long they’ll take, and whether you’re on pace to finish by your chosen time. Keep using Apple Workouts for your walks, runs, and workouts. Nudge adds the planning, motivation, and gentle reminders that help you build the habit of moving every day. Built for iPhone and Apple Watch, Nudge works with Apple Health to turn your daily step count into practical guidance you can use throughout the day. WHY PEOPLE LOVE NUDGE • Count down the exact number of steps you have left today • See how many walking minutes remain to reach your goal • Know whether you’re ahead, behind, or on pace • Set a daily goal and a “Finish By” time that fits your schedule • Review your daily and weekly progress to build lasting habits • Estimate calories burned from your walking activity • Receive optional reminders that help you stay on track • Celebrate when you reach your daily goal DESIGNED FOR APPLE WATCH Nudge was designed around the Apple Watch experience. Instead of opening your watch to rings, percentages, or complicated metrics, you see the one number that matters most: Steps Left Today. Swipe through simple views to check your countdown, review your progress, start a guided walk, or adjust your settings. Whether you have 800 steps or 8,000 remaining, Nudge helps you understand exactly what it will take to finish your day successfully. YOUR DAILY WALKING PLAN Big step goals can feel overwhelming. Nudge breaks them into something manageable. Based on your remaining steps, walking pace, and Finish By time, Nudge estimates how much walking you still need and suggests practical walk sessions to help you stay on track. One glance tells you whether you can finish with a quick walk now or whether it’s time for a catch-up walk before the day gets away from you. CONSISTENCY MATTERS MORE THAN INTENSITY Fitness isn’t about the occasional perfect workout. It’s about building the habit of moving every day. Review your daily and weekly history to see your progress, goal streaks, walking calories, and the days you reached your target. Small wins add up, and Nudge helps you see that progress over time. OPTIONAL REMINDERS Stay on track with helpful reminders throughout the day, including: • Morning briefings • Progress updates • Walk suggestions • Goal celebrations You’re always in control. Adjust reminder frequency, walking pace, Finish By time, and daily goals to match your routine. APPLE WATCH COMPLICATIONS Keep your progress visible throughout the day. Add Nudge complications to your favorite Apple Watch face and see your remaining steps, progress, or countdown with a quick glance, without opening the app. ONE WALK AT A TIME Whether your goal is 3,000 steps or 10,000, Nudge makes daily movement simple, visible, and achievable. Know exactly what’s left, take the next step, and build a habit that lasts. Nudge uses Apple Health, with your permission, to read step data.
