### 1/5 — Worthless

*2022-05-03*

It would be easier to build and create your own app from scratch versus trying to use this one.

### 1/5 — Worst app I’ve used

*2022-03-07*

This app is not user friendly and won’t even let me sign up. When entering data, It won’t let me select M/F or undeclared, and with nothing selected, you cannot move forward in the sign up process! Very frustrating and disappointing, as I wanted to use this to schedule classes at a new gym I just joined.

### 1/5 — Don’t bother wasting time

*2022-03-01*

Doesn’t work. Simply doesn’t work for anything. Even as simple as creating an account, it doesn’t let you. Instead the app just crashes when trying to make a booking or even creating an account. Im not wasting anymore time with this app.

### 1/5 — Black screen???

*2022-02-17, version 4.2.4*

Terrible app. 

Downloaded. Opened and only saw a black screen. Repeated multiple times. Same result.

### 1/5 — Can’t open it after downloading

*2021-11-22*

All I get is a black screen on my iPhone after downloading it.
