### 2/5 — Tout perdre

*2026-08-22, version 3.28.6*

Quand je vais sur d’autres app, celle de Nautilus perd l’entraînement en cours.

### 3/5 — Ugh

*2026-06-09, version 3.28.6*

Copiez donc heavy

### 5/5 — Satisfaisant

*2026-04-22, version 3.28.6*

Très bien encadré

### 5/5 — Entraîneur

*2026-01-19, version 3.28.6*

Derrick super bon entraîneur une machine

### 1/5 — Mostly useless

*2026-01-05, version 3.28.6*

The app is mostly broken. Reservations don’t work, messaging doesn’t work, it used to show you how crowded the gym was but that doesn’t work anymore, and the app is overall clunky and feels like a college student project.

### 1/5 — Application qui ne fonctionne jamais

*2025-06-19, version 3.20.3*

Cette application n’arrête pas de me déconnecter. Ça dit que mon mot de passe n’est pas bon, j’essaie de le réinitialiser, ça n’envoie aucun courriel. Le lendemain ça me connecte automatiquement comme si rien n’était, mais le jour d’après je me retrouve avec le même problème.

### 4/5 — Overall a good app !

*2025-06-06, version 3.20.3*

Bug free. Easy to use. Graphics and animations are from previous century

### 1/5 — App uses multiple tracking websites on login

*2025-05-08, version 3.20.3*

It tries to connect to many tracking and telemetry websites and utterly refuses to login unless I allow them. 

Why does this app need to contact evidon, thebrighttag, btstatic, googleadservices to let me use the gym membership I paid for. 

This is violating my privacy and should be looked into.

### 5/5 — Pour moi c’est correct

*2025-01-23, version 3.18.15*

Je ne suis pas la plus disciplinée mais je la consulte souvent. Je reserve mes cours de groupes et je consulte mon boomrang.

### 1/5 — Servers down

*2024-12-16, version 3.18.15*

Servers have been down over a week, can’t even use the app.
