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 large, colorful fish 6 meters below the surface—you’d love to dive down with a long breath and take unforgettable photos. With Apnea Trainer, that’s possible. With three training sessions a week, you’ll quickly double your time underwater.
The training principle is regularly used by freedivers. It originates from yoga and strengthens the diaphragm muscles, allowing you to fill your lungs with more oxygen and release more carbon dioxide when exhaling. The smart performance index automatically adjusts training times to your level—you’ll improve without having to do the math yourself.
Three training modes:
• Apnea Training – Inhale, hold, exhale. Optimal intervals for maximum performance improvement.
• Pranayama – Four-phase breathing for relaxation and preparation right before snorkeling or freediving.
• Custom Pro – All four phases freely adjustable from 0 to 240 seconds for competitive athletes.
Visual and audio instructions (voice prompts and haptic feedback) guide you through each phase. No need to think—just train.
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.
Motivating Streak System:
Stay on track and dive deeper and deeper. Maintain your daily training streak, progress through increasingly deeper zones, and collect over 35 awards for consistency, volume, and personal records. If you miss a day, a Freeze Joker saves your streak. Share unlocked achievements and new personal bests with a tap as a beautiful image on your social networks.
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 if they use Apnea Trainer for 3 minutes daily. For advanced athletes, consistent performance gains of 10 to 20 seconds within 10 days have been reported.
This app comes recommended by Tim Ferriss. I’ve been trying it for just 5-minutes every morning, which is really grounding. It’s a elegant way to improve your overall breathing incrementally with time. Plus, love the gong sound at the end. Great job developers!Tip: Enable “Voice Count Down”!
Great app for breath control
Qwertyuo
This app is not O2 or CO2 tables. It is a breathing regulation program, very good for controlling breath and relaxing for increasing depth and time as well as a less stressfulI way of training. If you want tables then use iholdbreath which allows you to practice tables. I use this as a warm up switch app do a table and then switch back. I have found this very effective.
Great help!

I've tried a few apps to help my spearfishing time underwater the breath up is definitely the most important part I learnt it primarily from this app! How long you should breath in, breath out, also how long to pause.I've never reviewed an app but this one has blown me away with the instantaneous results.Thanks chaps

This app is amazing for training, improving, helping and getting you ready for any dives. I have used this app for about one mouth, and already improving rapidly. I use it twice a day every couple of days I am making it harder for myself. I highly recommend this app.
