Your hands speak before you do. NailSafe is a nail-biting habit-support app: Desk Mode can help you notice the gesture, and weekly photos let you follow changes in your hands. Nail biting can go unnoticed: your hand may move before you become aware of it. NailSafe’s Desk Mode can help you notice the gesture and pause. DESK MODE — DETECTION • Prop your iPhone on the desk, front camera on, and work. • When Desk Mode detects a hand near your mouth, a soft chime can help you interrupt the gesture. • 100% on-device. No image is ever saved or sent. SEE YOUR HANDS CHANGE • Guided weekly photo, same framing every time. • Before/after slider from Day 0, timeline and estimated growth. • Proof you can look at — and share. THE METHOD BEHIND IT • Habit Reversal Training built in: notice, replace, see it change. • 90-second SOS when the urge hits: breathing, a competing response your mouth can't reach, your reason. • Relapse coach: a slip restarts the counter, never your progress. YOUR NUMBERS • Bite-free days, check-ins, completed exercises and weekly photos. • Daily 5-second check-in, trigger chart, 16 achievements. A PLAN BUILT ON YOU • A short quiz: which fingers, when you bite, why. • Reminders only at your risky moments, plus an evening nail-care nudge. HONEST, NOT INSTANT Nails don't recover overnight, and NailSafe never invents a finish line or promises a date. What you see is real: your own weekly photo, your own pace, your own proof. NailSafe is a habit-support tool. It is not medical advice and does not replace a health professional. NailSafe Pro: a weekly or yearly plan with a 3-day free trial for eligible new subscribers, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage in your Apple ID settings.

EYSK Jump turns your Apple Watch (or AirPods) into a precision jump rope counter — accurate to your own jump style, not a generic guess. ACCURATE, PERSONALIZED COUNTING A quick 10-second calibration test learns exactly how YOU jump, so every rep counts — no more missed reps or false counts from a one-size-fits-all sensor threshold. LIVE ON YOUR WRIST Start a session and watch your jumps, calories, and active time tick up in real time, right on your watch face — no phone required. GOALS THAT KEEP YOU MOVING Set your own daily Jump, Calorie, and Active Time goals, and track your progress as glanceable percentage rings on Today's screen. SEE YOUR PROGRESS Daily, Weekly, Monthly, and Yearly charts (bar or line, your choice) show exactly how you're trending, with period summaries for total, high, low, and average. A FULL HISTORY, ALWAYS WITH YOU Every session is saved and synced to your iPhone automatically, with a monthly calendar view showing every day you jumped. SHARE YOUR WINS Turn today's stats — or your all-time best day — into a beautiful, ready-to-share card. Pick from 16 built-in images or add your own photos from your library, and sign it with your name in an elegant script for a card that's unmistakably yours. WORKS WITH APPLE HEALTH Pulls your basic profile (with permission) to personalize calorie estimates and logs every session as a real Apple Health workout. CLIMB THE WORLD RANKINGS Every jumper is automatically on the World Rankings — see how you stack up, filtered by World, Country, or Region, by age or gender, and by Today, Week, Month, Year, or All Time. Your nickname shows publicly once you're 16; younger jumpers are always shown anonymously. EARN BADGES AS YOU GO Beat yesterday's jump count, and you'll earn a Beat toward your current badge — collect 10 Beats to level up, and clear all 10 Levels to unlock the next badge, from Bronze all the way to Infinite. Your current badge shows below on your Home screen, and always appears on your Share card too. CHALLENGE A RIVAL Pick anyone on the World Rankings as your rival and go head-to-head. Beat their jump count on a calendar day — once it's ended for both of you — and you'll earn a bonus Beat, with a Home screen scoreboard showing exactly how close the race is. MONTHLY GROWTH BONUS Jump 20% more than you did last month and earn a bonus +3 Beats — credited the moment your month passes 120% of last month's total. EVENTS Join special challenges and world goals, open to everyone or to selected countries. Reach the target, earn Beats, and watch jumpers around the world go for it together. KIDS MODE Switch on Kids Mode in Preferences — on the Watch app or the iPhone app — and Today's/Home's screen turns into a simple, playful view for younger jumpers: a dog and cat alongside today's jump count, instead of the full stats table. GREAT FOR KIDS & TEENS Simple enough for young jumpers to pick up in minutes — clear daily goals, an accuracy-calibrated counter, and fun milestone badges keep practice consistent. Jump rope is also a favorite go-to activity many parents encourage for active, growing kids. Perfect for school fitness challenges, sports conditioning, or just building a healthy daily habit. NO WATCH? NO PROBLEM Own AirPods (Pro, Max, or 3rd generation and later) but not an Apple Watch — or just not wearing it today? Start a session right from your iPhone's Home screen and count jumps straight from your AirPods' own motion sensor, calibrated to your style just like the Watch. Made for Every Jumper Whether you're training for boxing, building cardio endurance, or just love the rhythm of a rope, EYSK Jump makes every session count — literally.
