## What is Apnea Trainer?

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.

### 4/5 — Optimierungspotenzial

*2026-10-14*

Leider wird kein Audio mehr abgespielt, wenn man den Bildschirm ausschaltet. Das ist beim Üben am Abend dunklen Zimmer sehr schade, zudem würde ein Darkmode der App gut tun.

### 5/5 — Your breath hold trainer in your pocket

*2026-08-13, version 5.5.2*

The app has been recently updated/upgraded. It now includes a training plan based on your goals, different training options beside the plan and some nice statistics that visualise your progress.

The new version is nice to use and makes you come back for training every day, for a proper training session or for some smaller Breath work.

So its easy to improve your Apnea skills.

### 5/5 — Tolles Programm - funktioniert super

*2026-08-03*

Ich musste mich ein bisschen mit der Nutzung der App beschäftigen aber dann war alles klar. Mit Hilfe der App habe ich gute Fortschritte gemacht. Vielen Dank 🙏

**Developer response:** Vielen Dank für dein Feedback. Kontaktiere mich doch gern über die Funktion in den App Settings. Ich würde gern verstehen wie ich den Einstieg noch leichter gestalten kann :)

### 5/5 — Top!

*2026-06-28*

Ich bin wirklich begeistert. Ich habe die App nun schon viele Jahre, und sie wird immer noch aktiv weiterentwickelt. Das Streak-System finde ich gut, aber der individuelle Trainingsplan ist mega. Blue Hole im Herbst kann kommen 😊

### 5/5 — Feedback berücksichtigt!

*2026-06-09*

Vielen Dank für die schnelle Reaktion. (Ich hatte vorgeschlagen, dass man den akustischen Countdown abschalten kann.)
Cool😇

**Developer response:** Danke für das Feedback. Die Funktion kommt diese Woche mit einer kleinen Verbesserung zurück ;)
Es wäre super, wenn es dir gefällt und du dann deine Bewertung noch einmal anpassen könntest.

### 4/5 — almost perfect

*2024-08-05, version 4.2*

I am missing a more custom timer like doing wim hof etc

### 4/5 — Great app with some room for improvement

*2024-05-30*

I really love this app and use it routinely to help relax and improve my breathing. Hoping the developers can improve the voice counting as it’s a bit buggy and would be a much better experience after this minor adjustment

**Developer response:** Thank you for your feedback. Please get in touch with me to provide more detailed information. I would be happy to resolve the audio issue. Since I cannot reproduce it on my test devices, I would some more info about this.

### 5/5 — Training

*2024-01-10*

Leicht verständlich und der Erfolg kommt schon nach 3 - 4 Einheiten 👌🏼

### 5/5 — Excellent

*2023-12-31*

### 5/5 — Tiempo de apnea

*2023-08-06, version 4.2*

## Version history (last 5 releases)

### 5.8.3 — 2026-10-23

Smoother transitions when starting and ending free training. A subtle breathing animation makes the chest follow your breathing rhythm. Transitions in Cyclic training have also been refined.

### 5.8.2 — 2026-10-21

Calmer guidance in apnea plans, with self-paced breathing during warmup and recovery. The final breath before a hold is marked more clearly. New, shorter voice recordings and improved countdown timing; music can keep playing alongside the app. Personal notes for saved sessions, clearer forecast and measured progress, and a larger stopwatch tap area. Improved Apple Watch coordination.

### 5.8.1 — 2026-10-13

• Clearer training view with a compact Liquid Glass card and a distinct preview of the next breathing phase.
• Training progress and breath-hold milestones appear directly on the circle.
• Improved layout on small iPhones and iPads, including larger text sizes.

### 5.8 — 2026-10-11

• During plan workouts, the next action and its duration are now shown; before the final inhale, the following breath-hold is also visible.
• Fixed the free-training countdown and restarting after a session ends.
• Simple countdown switch in the speaker dialog, shared with advanced sound settings. Easier access to the logbook in your profile.
• New English training voice with standard and extended guidance, plus revised countdown scheduling.
• Settings are grouped by topic. Voice options appear only when Voice is selected.
• Expanded dive logbook for depth, dynamic and static apnea, with disciplines, personal bests and progress charts.
• New sick leave option: protect your training streak while you recover, without using jokers. Training reminders pause too.
• Clearer training previews and CO₂ tables with progressively shorter rests between holds.
• Adjust the final inhale for each session.
• Cooldown starts immediately after the final breath hold: breathe at your own pace, see the time remaining and feel a double vibration at the section change.
• Clearer audio and countdown options, plus follow-up plans that preserve your progress.
• Training frequency changes now apply to the current plan week, with a short confirmation animation and an immediately updated overview.

### 5.7.4 — 2026-09-13

I reworked the preparation before a breath-hold: maximal holds now start with a calm breathe-up, and every hold in a training plan gets one long, full breath instead of four seconds.
