### 1/5 — The App is Dead

*2026-07-04, version 2.4*

This App needs updating.

### 1/5 — No working

*2026-06-19, version 2.4*

Crashes upon opening still

### 1/5 — Zéro étoile!!

*2026-02-09, version 2.4*

L’application ne fonctionne pas sur IPhone 17. Impossible d’ouvrir l’application, elle se referme automatiquement.

### 1/5 — Completely useless

*2026-02-07, version 2.4*

Our SAR team spent thousands of dollars on NAO+ Headlamps and now we can’t adjust the settings because the app crashes as soon as you click it. None of us can turn off the blinking light in the back and with 5 ppl working on a patient all you can see is blinding blinking lights instead of what you’re doing.

### 1/5 — الرطبيق

*2026-01-27, version 2.4*

لايعمل

### 4/5 — Connexion pour configurer.

*2026-01-23, version 2.4*

Aucun problème d’utilisation avec mon iPhone 11, mais inutilisable avec mon iPhone 17 Pro. C’est pour configurer ma réactif+.

### 1/5 — Garbage

*2026-01-14, version 2.4*

Repeatedly crashes on iPhone 21 Pro Max running 26.1 iOS. Rebooted the phone. Deleted and reinstall the app. I just purchased my Swift RL and according to Google this app is supposed to function with this headlight. The headlight is going back to Amazon if PETZL doesn't address this.

### 1/5 — Doesn’t work at all

*2026-01-07, version 2.4*

App just doesn’t open. Crashes on loading screen. Tried on a number of different devices - assuming developers have just abandoned it and doesn’t work on newer iOS versions

### 1/5 — No longer loads on iOS 26.2

*2025-12-20, version 2.4*

Used to be quite useful when first installed in 2017 but no longer loads on latest iOS. Icon appears but no content shows. Now disappointing.

### 1/5 — Crashes

*2025-12-09, version 2.4*

Doesn’t work. Sent flashlight back
