What is jet lag?
By travelling rapidly through more than 3 time zones, your body has not had time to adapt to its new destination. This is called the desynchronization effect. Your body thinks it's the morning, whereas it's time to go to bed! In short, these are difficult moments that can persist for several days and ruin the beginning of a stay.

Chronobiology :
Did you know that? Our body, as a whole, is subject to an endogenous cycle of about 24 hours. This is the circadian cycle.  The main synchronizer of our internal clocks is light: thanks to it, our body gives us the signal to sleep and gives rhythm to our day. Light is the main synchronizer but there are other secondary synchronizers such as: food, temperature, physical exercise....

The solution:
And so it is, quite naturally by relying on these synchronizers that the Gowwiz program will shift your body's circadian cycle so that it is in line with your destination.
But be careful, each person has his/her own cycle and that is why Gowwiz offers a personalized program.
And above all, don't be discouraged, don't give up. Just because you miss a day or an action doesn't mean you should give up. It's like a diet, a gap, an oversight, it doesn't matter!

### 5/5 — Je recommande

*2025-11-16*

J’ai utilisé Gowwiz lors d’un voyage à New York et j’ai adoré !
L’application est intuitive, les conseils aident vraiment contre le jet-lag et la fonctionnalité médicament permet de ne pas être décalé dans un traitement à heure fixe.

**Developer response:** Bonjour DayanaFv, C'est merveilleux d'apprendre que vous aimez l'application ! Votre satisfaction nous motive. Si vous avez des idées pour améliorer votre expérience, n'hésitez pas à les partager. Merci de faire partie de notre communauté ! Cordialement, Gowwiz

### 1/5 — Broken app

*2024-11-15*

Sorry, but your app literally doesn’t work. Can’t get in to it

### 5/5 — Long term review

*2024-06-01*

Follow the recipe and season to taste, all good 👍. With a bit of anticipation allows me to better handle jetlag.

**Developer response:** Bonjour GerryD44, C'est fantastique d'entendre que vous appréciez notre application ! Votre enthousiasme nous encourage énormément. Nous sommes ravis de vous avoir parmi nous et espérons continuer à vous offrir une expérience exceptionnelle. Cordialement, Gowwiz

### 5/5 — Super app

*2024-05-30*

Sensible au décalage horaire, cette app m’a vraiment aidé lors de mon voyage au Vietnam, elle est complète et propose pleins de fonctionnalités super utiles, bravo

**Developer response:** Bonjour, Quel retour incroyable à lire ! Nous sommes vraiment heureux que l'application vous enchante autant. Votre soutien chaleureux nous touche profondément. Nous espérons continuer à vous offrir une expérience exceptionnelle. Cordialement, Gowwiz

### 5/5 — excellent conseils

*2024-05-16*

voyage New-york Paris.
les suggestions proposées ont été très judicieuses.
ça va devenir mon compagnon voyage long.

**Developer response:** Bonjour, C'est formidable de savoir que l'application vous est si utile ! Votre retour positif nous touche vraiment. Merci encore pour votre soutien ! Cordialement, Gowwiz

### 5/5 — Efficace

*2023-08-01*

Efficace! J’étais sceptique mais en suivant les recommandations de l’appli je me suis recalée facilement! Je garde pour mes prochains voyages !

### 2/5 — Bof bof

*2023-07-29*

Ce que je redoutais arrive : yeux grands ouverts à 2h du matin et impossible de se rendormir.
J’en profite pour écrire quelques mots en commençant par dire qu’il y a quelques conseils intéressants et que le graphisme est très sympa… mais que tout cela reste très basique à mon goût. A 4,99€ je n’en n’ai pas pour mon argent. Les applis à ce prix offrent généralement plus d’où ma déception. Mon prix psychologique est à 2,99€. Quelques pistes de progression :

- Le premier problème est que l’appli ne gère pas les escales. CDG > SIN + escale 5h + SIN > AKL. L’appli reprend bêtement les conseils du 1er vol sur le second.
- Pas de conseils quand le réveil en pleine nuit est là.
- J’ai l’impression que les conseils sont toujours les mêmes et on se lasse donc très vite.
- Je n’ai pas trouvé de conseils sur la gestion d’éventuels somnifères ou Melatomine.
- Peu de conseils si le calage ne se fait pas après 24-48h
- Je m’attendais à une appli beaucoup plus personnalisée où on puisse par exemple enregistrer ses heures de sommeil et de réveil et suivre son « calage ».
- Pas ou peu de conseils sur les repas

J’ai lu qu’il y avait une nouvelle version améliorée dans les tuyaux. Curieux de voir les corrections apportées,

**Developer response:** Bonjour et merci de votre commentaire. 
Pour gérer les trajets multi-vols, nous vous conseillons de saisir votre trajet complet manuellement (onglet saisie manuelle), dans ce cas, les conseils s'adapteront sur toute la durée du voyage. 
Nous avons effectivement pris le parti de ne pas conseiller sur la prise de somnifères ou de mélatonine, cette application aide à la resynchronisation naturelle. 
Les conseils sur les repas ont été rédigés par une dieteticienne-nutritionniste avec des exemples précis de menus pour ceux qui voyagent vers l'Ouest et pour ceux qui voyagent vers l'Est.
Une professeure de Yoga a imaginé des exercices spécifiques à pratiquer lors des longs voyages.
Enfin, pour 4,99€ vous avez un accès illimité à l'application et donc à toutes les prochaines évolutions. En espérant vous accompagner de nouveau lors de vos prochains voyages!

### 5/5 — Très efficace

*2023-03-24*

Excellente app qui m a permis de très bien gérer un décalage horaire de 4h. Moins de 24h pour récupérer totalement. 
Plus

Enrôlement simple

Visuel simple et joli

Très bonne gestion des fuseaux horaires 

A bien fonctionné. 24h après le vol je n avais plus de sensations de fatigue 

Suggestions

Possibilité de mettre plusieurs vols pour gerer les vols à étapes. 

Notifications pour les recommandations 

Rajout de recò de nourriture et boissons

Horaires de déjeuner/dîner

Expositions aux écrans ou pas

Rajout de l exercice physique avant de partir/dans l avion/après

### 1/5 — Aucun intérêt

*2023-03-21*

Les conseils donnés sont du bon sens, pas besoin de payer une appli pour me dire de dormir dans l’avion Sur un Paris -New York l’appli me conseille d’aller me coucher à 3 heures du matin ?! Après une première nuit blanche compte tenu de mon vol matinal !!!!

MAJ: merci de votre réponse et précision 
Ce n’est effectivement pas très clair

**Developer response:** Bonjour et merci de votre message.
Quand Gowwiz vous conseille de faire une nuit blanche car le vol est matinal, en effet, nous déplaçons le sommeil dans l'avion (même si cela n'est pas forcément facile, d'où un sommeil plus court). Cela vous permet de tenir ensuite jusqu'à 3h du matin (heure Paris) soit 21h (heure NY). Une nouvelle version disponible en avril mettra plus en évidence les heures arrivée/départ qui peuvent effectivement prêter à confusion.

### 5/5 — Vraiment efficace !

*2023-02-27*

Testé à l’aller et au retour d’un voyage Paris-New York: j’ai bien appliqué les consignes, et ça marche ! Une totale satisfaction, car je suis habituellement très sensible au décalage horaire.
