Ranked in the top 5 best-selling sports apps in Germany, Australia, the UK, and France. ----- Description ----- The precise breath-holding training app for freedivers, snorkelers, and anyone who wants to hold their breath longer. Imagine you’re snorkeling in the ocean on vacation and see big, colorful fish 6 meters below the surface—you’d love to dive down on a single breath and take unforgettable photos. With Apnea Trainer, that’s possible. By training three times a week, you’ll quickly double your time underwater. Your personalized training plan: Answer a few short questions about your skill level and your goal—Apnea Trainer will use this information to create a training plan spanning several weeks that’s tailored just for you. Each session is scheduled and builds on the previous one, so you’ll see measurable improvement week after week. Your progress is tracked automatically—all you have to do is train. Four training modes: • Apnea Training – Inhale, hold your breath, exhale. Optimal intervals for maximum performance improvement. • Pranayama – Four-phase breathing for relaxation and preparation right before snorkeling or freediving. • Cyclic – Cyclical breathing training in rounds with hold and recovery phases that specifically increases your CO₂ tolerance. • Custom Pro – All four phases freely adjustable from 0 to 240 seconds for competitive athletes. The smart Performance Index automatically adjusts training times to your level—you’ll improve without having to do the math yourself. Visual and audio cues (voice prompts and haptic feedback) guide you through each phase. No need to think—just train. Apple Watch: Start and control your workout right from your wrist. During the exercise, you’ll see your heart rate in real time and be guided through each phase by gentle vibrations—without having to look at your iPhone. Stopwatch & Progress: With the built-in apnea stopwatch, you can measure and save your best breath-hold attempts. Track your personal bests on weekly, monthly, or yearly charts and share special milestones with friends. Logbook for real dives: Record your freedives with location, map preview, duration, max depth and notes — with location suggestions, and depth in meters or feet. Your training sessions appear in the logbook too, including a heart-rate graph per session. Widgets & Apple Health: Three home screen widgets show your streak, weekly goal and today's training status at a glance. Live Activities bring your running session to the Lock Screen and the Dynamic Island. Completed sessions can be saved to Apple Health as mindful minutes. Motivating Streak System: Stay on track and dive deeper and deeper. Maintain your daily workout streak, advance through deeper and deeper zones, and earn over 35 awards for consistency, volume, and personal records. If you miss a day, a “Freeze” joker will save your streak. Share your unlocked achievements and new personal bests with a single tap as a beautiful image on your social media. Privacy & Sync Without an Account: Your progress is securely synced across all your Apple devices via iCloud without requiring registration or an account. The data is stored exclusively in your private iCloud database—no tracking, no sharing, and the highest privacy standards. More than 10,000 active users confirm its success: Beginners can double their performance within 7 days by using Apnea Trainer for 3 minutes daily. Advanced athletes have reported consistent performance gains of 10 to 20 seconds within 10 days.

LaneSync turns two iPhones, or an iPhone and an Apple Watch, into a finish-line timing system for sprints. No internet, no Wi-Fi network and no extra hardware: the devices talk directly to each other, so it works on any track or field. HOW IT WORKS • Sync: put the two devices side by side and tap Sync clocks. • Start: the start device calls "Runners, take your mark… Set…" and fires a starting gun after a random pause. The clock starts on the gun. • Finish: the finish iPhone films the line and detects every runner who crosses it, on the device, using body-pose detection. • Review: bring the devices back together. Step through each finish frame by frame, mark the exact moment each chest crosses the line, assign it to a runner and save. Clock drift is measured at both ends of the session and corrected, and times are shown in hundredths, rounded up as fully automatic timing does. BUILT FOR COACHES AND ATHLETES • Two phones, or one iPhone with an Apple Watch as the starter • Any distance from 5 to 1,000, in metres or yards • Groups of runners: time a whole squad, with several runners per clip • History by day and session, with PB and SB badges • Share a result card, and save finish clips to Photos • Export every time as CSV, or share sessions and personal bests (LaneSync Pro) • Light and dark appearance YOUR FIRST WORKOUT IS FREE Time your first workout free: a whole session, with as many runs as you like, reviewed and saved. After that, more workouts with that iPhone as the finish phone need LaneSync Pro on it, or on the start phone: a start phone with Pro covers the finish phone it times with. Everything you save stays free to view: History, every result with its PB and SB badges, result cards and clips saved to Photos. You can delete any of it at any time, and nothing you record is ever hidden. LANESYNC PRO An optional subscription for coaches and athletes who time regularly: • Unlimited workouts, and your start phone covers any finish phone it times with • Export every time as CSV, and share sessions and personal bests as text • Progress charts of every run at each distance • Personal-best progression over time • Each runner's own trend, or the whole squad on one chart • Last run against the PB, and the average of the last five runs New subscribers start with a 7-day free trial. If your subscription ends, everything you saved stays in History, and a session you've already started can always be finished and saved. APPLE WATCH AND HEALTH When the watch is the starter, LaneSync starts a workout session (HealthKit) only so the watch stays awake during the countdown with your wrist down. It reads no Health data and saves no workouts. PRIVACY No account, no ads, no analytics, no tracking. Your times, runner names and clips stay on your devices. SUBSCRIPTION TERMS LaneSync Pro is an auto-renewable subscription, available monthly or yearly. New subscribers start with a 7-day free trial (once per Apple ID). When the trial ends it converts automatically to the paid plan you chose and your Apple ID is charged that plan's price, unless you cancel at least 24 hours before the trial ends. Without a trial, payment is charged to your Apple ID when you confirm the purchase. The subscription renews automatically at the same price and for the same period unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. Manage or cancel any time in Settings › your name › Subscriptions; cancelling keeps Pro until the end of the trial or of the period you've paid for. Prices are shown in the app and may vary by country. Terms of Use: https://www.apple.com/legal/internal-services/itunes/dev/stdeula/ Privacy Policy: https://moonyose.github.io/lanesync-support/privacy.html Requires two iPhones, or an iPhone and a paired Apple Watch with LaneSync installed (Apple Watch works with iPhone only). The finish iPhone needs its camera.
