### 2/5 — Still on free trial signed up for monthly… problems already!

*2026-06-17*

App will not even let me enter what they call "measure units„ 
Haven't really had a chance to fully evaluate the app yet,  I will be back later and update review

### 5/5 — Au top!!!!

*2025-09-26*

J’utilise cette application de cardio training depuis quelques jours et je suis vraiment conquis! Les séances sont variées, bien rythmées et adaptées à tous les niveaux. On peut facilement suivre sa progression grâce aux statistiques claires et motivantes. 
Les programmes sont personnalisés, ce qui permet de garder la motivation sans jamais tomber dans la routine. L’interface est intuitive et agréable, et les explications sont simples à suivre, même pour un débutant. Résultat : je me sens en meilleure forme, j’ai plus d’énergie au quotidien et j’ai retrouvé le plaisir de m’entraîner. Franchement, une appli incontournable pour progresser efficacement en cardio ! Je vous conseille de la télécharger !!!

### 5/5 — Idéal pour se motiver

*2024-11-29*

Moi je voulais perdre du poids et les challenges sont géniaux pour tout type de niveau

### 1/5 — Intérêt?

*2024-11-18*

Application peu utile. Ou alors si l’on se contente de peu de suivi ou de peu de sérieux. 
Comment être capable de fournir de bonnes informations sans données de fréquence cardiaque!? C’est le minimum pour fournir de bonnes informations d’entraînement. 
Bref du temps de perdu.

### 5/5 — Enfin !

*2024-09-22*

Enfin une app qui me permet d’enregistrer mes séances cardio et d’obtenir des statistiques. Depuis le temps que je cherchais une app comme celle-ci. 
Mais ce n’est pas tout. L’app permet de calculer sa VMA (vitesse maximale aérobie), sa VO2max, pour avoir une idée de notre niveau de forme et de notre âge physiologique. 
L’app calcule aussi l’espérance de vie gagnée grâce à notre activité cardio Indoor. Et bien d’autres choses encore. 
Et pour les plus sportifs d’entres-nous, on peut faire des challenges et se mesurer aux autres Whizzers sur tapis, vélos et rameurs. 
Cette app est géniale.

### 5/5 — Super Appli révolutionnaire !

*2024-09-22*

Enfin une appli qui me permet de garder une trace de toutes mes séances de cardio en salle ( sur mon tapis et vélo). Je n’ai plus besoin de faire une capture d’écran ou de noter mes temps dans un carnet ! Désormais, j’ai un vrai historique ! 
Et je sais enfin ce que je vaux par rapport aux autres femmes de mon âge sur certaines distances de courses en « salle »!  Cela me permet de connaître mon niveau de forme , de me comparer et de m’améliorer ! C’est grisant , motivant , ça me stimule pour des défis ! 
Je peux aussi m’entraîner pour améliorer ma VMA et avoir enfin une donnée rapide et fiable de celle-ci! 
APPLI au TOP !

### 5/5 — Enfin l’app que j’attendais depuis des années !

*2024-09-08*

Plus besoin de faire des photos pour avoir un historique et des statistiques de mes séances sur machines cardio ! Je peux aussi comparer mes performances à celles d’autres utilisateurs, faire des challenges avec mes amis, mesurer l’espérance de vie que j’ai gagné en m’entraînant ! C’est la seule app qui permet de mesurer sa VMA, sa VO2max et son âge physiologique, c’est super cool !!!
