• Get real-time information about the state of the headlamp from a smart phone or tablet:
- battery charge level
- remaining burn time
- the headlamp profile currently active

• Five predefined profiles adapt performance to the activity: multi-activity, trail running, trekking, mountaineering and bivouac. Each profile has a choice of multiple lighting levels

• Create custom profiles:
- customize the headlamp to best suit the need

• LIVE mode:
- access control of the headlamp from your mobile device with Bluetooth®
- adjustment, in real time, of the brightness and burn time
- display of battery charge level

• Emergency light signal:
- if an alert needs to be sent, a brief message can be programmed into the smart phone and transformed into a Morse code light signal by the headlamp
- useful when there is no cell reception or other means of communication

Worst app!

I bought this lamp because of this app however you should be able to adjust profiles with the lamp off number one number two sometimes i will open the app and it will just randomly cycle through modes like a ghost, most importantly though it forgets your profile settings!! When you launch the app and it's open for a little while it will show you totally different values for your settings in your lamp you must re-close that app and reopen it again it'll show you correct profiles however updating your lamp profiles is a crapshoot whether it will upload the correct values or not or the random values that it just sometimes sets a big disapointmen!

effectively you can't setup your profiles while in off line mode. But the battery consumption in bluetooth mode is very insignifiant. Can you tell us what kind of problems do you have when loading profiles ? Please write to the following adress:
The live mode is a real live mode that means parametes are lost when you leave this mode (by navigating in other app menus or killing the application). But it does not loose anything when your phone go to sleep mode (only if you switch off your phone).
Best regards


PETZL Reactik headlamp

Dependable and powerful lighting as promoted. Too many times have I purchased an outdoors product with expectations from advertisement capability, just to be let down. Cost is affordable for quality of purchase. Thought had problem with battery, contacted customer service, same day reply and with just a couple communications the rep had me back up and running. Was simple human error(mine). Am an outdoors recreation and hunting guide. Clearly lighting is of UTMOST necessity. Recommend PETZL to all fellow colleagues. In my circle of ppl in same industry are almost all using PETZL with satisfaction on professional level. CANNOT operate without lighting. No room for error/malfunction in real time operations in deep country. Therefore PETZL is my go-to equipment of choice. Confidently recommend to all, for personal and professional use. Good luck, God Bless and God Speed to all. Get outdoors and enjoy the fresh air! V/r, state of Maine.

Not usable on an iPhone X

It’s the first time I have ever encountered an iOS app where you can’t close or get past the “on-boarding” or initial tutorial screens. The last screen has a very small “X” in the top right corner - right under the battery level indicator - that no matter how hard you try, it cannot be accessed. My suggestion would be to Q/A this app on an iPhone X and re-submit to the App Store. As for the rest of the app, well I have no idea. Can’t get to it. C’mon Petzl ! You can do better.
