## What is Pulsalarm?

PULSALARM warns you via vibration or warning tone when you exceed your set upper and lower pulse limit and thus supports you in your pulse-based training. You can train as usual with your favorite fitness or running app. All you need to do is install PULSALARM on your Apple Watch.

Features of the Apple Watch App:
- Vibration and/or warning tone when the set pulse limits are reached
- Vibration and/or signal tone when returning to the set pulse range
- Pulse limits can be deactivated individually
- Large, easy to read display of the current pulse
- Fast adjustment of pulse limits (also possible while running)
- Works together with all known fitness, training and running apps that can be started on the Apple Watch
- Does not write data to Apple Health
- You can use the app on your Apple Watch without having your iPhone with you

Features of the iPhone App:
- Calculation of your maximum heart rate
- Individual calculation of the 5 intensity ranges (depending on your maximum heart rate) 
- Adoption of the pulse limits from the training zones
- Setting the maximum and minimum pulse limit 
- Large display of the current pulse

Important note: without the use with an Apple Watch, the functional range of the app is limited, as no permanent pulse measurement can be carried out.

No advertising, no tracking, no third-party codes. Developed with passion and programmed in Germany.

Why use PULSALARM additionally? 
Many running apps include the pace as a target in their training plans. However, the same speed can mean a high intensity for one person and a low intensity for another. It is therefore helpful to consider your heart rate instead of speed to determine and maintain the right training intensity. 
PULSALARM helps you to do this. It turns your Apple Watch into a heart rate monitor. 

What is the big advantage?
You no longer have to look at your Apple Watch during your workout and still know whether you are exercising within your personal heart rate zone. Also ideal in colder months, when your Apple Watch is hidden under a jacket or long-sleeved shirt and you can't look directly at the display while running.

For whom is PULSALARM suitable?
- Ideal for run beginners, as they can control themselves better and protect themselves from overstraining.
- Ideal for ambitious runners, as they can train more specifically in their intensity ranges and thus increase endurance and performance.
- For all athletes and fitness enthusiasts who are interested in heart rate monitoring during their training with their Apple Watch.

Summary:
With the PULSALARM app on the iPhone you can determine your 5 intensity ranges based on your maximum heart rate. You can enter your maximum heart rate directly or have it calculated. Set your personal maximum heart rate limit, which you do not want to exceed during training, and your minimum heart rate limit. When these limits are reached, your Apple Watch will alert you by vibrating and/or beeping.

## Key features

- Vibration/tone alerts for pulse limits

- Large pulse display

### 4/5 — Grundsätzlich ok

*2026-04-03, version 1.1.1*

Die App macht grundsätzlich genau das, was sie soll. Einrichtung und Nutzung sind einfach und übersichtlich, alles wirkt sauber umgesetzt und funktioniert zuverlässig.

Ein großes Manko gibt es allerdings: Sobald der Audio-Alarm aktiviert ist und man parallel über die Apple Watch Musik (z. B. über Apple Music) hört, wird die Wiedergabe beim Alarm unterbrochen – was an sich verständlich ist. Problematisch ist jedoch, dass die Musik danach nicht automatisch wieder startet. Das ist im Alltag ziemlich störend und nimmt ein Stück Komfort.

Hier wäre es wünschenswert, wenn die App die vorherige Wiedergabe nach dem Alarm automatisch fortsetzt.

Insgesamt eine gute App mit solidem Funktionsumfang, aber mit Verbesserungspotenzial bei der Integration in bestehende Audio-Wiedergaben.

### 5/5 — Great and eazy

*2026-02-21*

The app is really easy. The alarm doesn’t start until you get into your zone and then you get alerted when you’re above and below. Its nice you don’t have to deal with alerts before you get to your zone. Im glad i got this

### 5/5 — Funktioniert

*2026-01-12*

Hab eine Pulswarnung fürs Ausdauertraining gesucht. Gerade installiert für iphone 14pro und apple watch 10. funktioniert. Was noch nützlich wäre sind unterschiedliche vibrationsmuster für drüber und drunter (zb nur kurz kurz kurz, lang lang lang - damit man es direkt erkennt ohne auf die uhr zu schauen - gerade wenn man in einem sehr engen bereich trainiert)

### 1/5 — Doesn’t work anymore

*2026-01-11*

Use to work in November, but now it always shows 0 for the pulse

### 2/5 — Important - Only Works When App Is Open On Watch

*2025-08-18*

This app only works if it’s open on your watch. 

I prefer something that works in the background automatically.

Other than that, it works great!

### 5/5 — Absolut empfehlenswert!

*2025-06-22*

Die Pulsalarm App hat mir nach einer schweren Herzerkrankung möglich gemacht, dass ich mich traue, mich wieder ganz normal zu bewegen, weil ich dann sicher sein konnte, dass ich rechtzeitig erfahre, wenn mein Puls zu langsam oder zu schnell ist.

### 5/5 — A gem for heart rate notifications on the watch

*2025-05-22*

This app may not have been updated in years, but it still works flawlessly—and honestly, it’s exactly what I need. It’s a simple, no-frills heart rate alert app for Apple Watch that does one thing very well: it notifies me when my heart rate exceeds a threshold I set.

That might sound basic, but for me, it’s potentially life-saving. I use it while working in the yard, where sweating doesn’t cool you down like it should. My heart rate is the best early warning sign I have for overexertion, and this app helps me recognize heat exhaustion before it’s too late.

I love that I can launch it right from the watch with a simple tap, or use it alongside my go-to fitness tracker. It even claims not to collect user data, which is a rare and appreciated touch.

Apps like this—lightweight, focused, and respectful of your privacy—are rare. It’s a hidden gem, and I hope it keeps working for years to come.

### 5/5 — Perfekt!

*2025-04-07, version 1.1.1*

Funktioniert einwandfrei, ich bin begeistert.

### 5/5 — Genau was ich gesucht habe

*2025-04-06, version 1.1.1*

Perfekt für mein Training. Macht genau das, was ich erwarte. Empfehlenswert.

### 5/5 — Great app for fat burning zones etc.

*2025-02-04*

Been looking for an app like this for a while. Vibrates when your HR is outside your preferred exercise zones.

## Frequently asked questions about Pulsalarm

### What does Pulsalarm do?

Pulsalarm alerts you via vibration or a warning tone when your heart rate exceeds or drops below your set upper and lower pulse limits. This helps you train effectively within your target pulse zones, ensuring you maintain the right intensity for your workouts.

### How does Pulsalarm work with my Apple Watch?

You install Pulsalarm on your Apple Watch. It then monitors your heart rate and sends alerts directly from your watch. It can work with your favorite fitness, training, or running apps that are also started on your Apple Watch.

### How do I set my pulse limits?

The iPhone app allows you to calculate your maximum heart rate and then defines 5 intensity ranges based on that. You can then set your personal maximum and minimum pulse limits within these zones. These limits can be adjusted quickly, even while running.

### Can I use Pulsalarm without my iPhone?

Yes, you can use the app on your Apple Watch without having your iPhone with you. The watch will still monitor your heart rate and provide alerts based on the limits you have set.

### Is Pulsalarm suitable for beginners?

Yes, it is ideal for run beginners as it helps them control their effort better and avoid overtraining. By staying within their target heart rate zones, beginners can train more safely and effectively.

## Version history (last 3 releases)

### 1.1.1 — 2022-02-16

In this update, some features are added that users of my app had requested and now make the app even more user-friendly. 
- Now also works with always-on display on the Apple Watch
- New setting: warning tone only once when leaving the pulse limit
- Adoption of the pulse limits from the training zones
- Pulse lower limit setting reduced to 30 BPM
- Pulse upper limit setting increased to 220 BPM


And thanks for your bug reports:
- Elimination of a bug that caused music playback to stop on certain settings.
- Elimination of a bug that in some cases caused the lower pulse limit not to be disabled

And one more note:
Since the introduction of the always-on display, for battery life reasons, the data transfer from the Apple Watch to the iPhone was changed. This resulted in the pulse only being transmitted when the Apple Watch is in an active state. Therefore, it may happen that the pulse display on the iPhone is delayed. I am still working on solving this particular case, which only affects the display on the iPhone.

### 1.1 — 2021-08-23

Minimum possible pulse decreased to 30 BPM
Maximum possible pulse increased to 220 BPM
Single notification option added

### 1.0 — 2020-06-08

No release notes.
