### 1/5 — NO USA APP

*2022-05-14, version 2.0.5*

ANY DEVICE SOLD IN THE USA DOESN’T GET APP SUPPORT. PLEASE GET US AN APP WE CAN USE OR ALLOW USA SERIAL NUMBERS TO BE USED IN APP.

### 1/5 — The app doesn’t detect my serial number.

*2022-05-08, version 2.0.5*

App doesn’t work as it should. It won’t detect the serial number of my device, so I can’t complete registration. Trash communist Chinese app.

### 1/5 — WARNING

*2022-04-30, version 2.0.5*

I am unable to delete this app after installation.  It shows back up any time my phone is restarted.  I am suspicious that it may be a virus of some sort, in my opinion.

### 1/5 — Junk

*2022-04-07, version 2.0.5*

Downloaded the app and tried to register. SaId my serial no. did not exist so that was the end of registration.

### 1/5 — Won’t take SN.

*2022-03-29, version 2.0.5*

Doesn’t work whatsoever.

### 1/5 — Unusable App

*2022-02-09, version 2.0.5*

Can’t register because app doesn’t recognize serial number. Zero tech support. Fail! Should be no stars!

### 1/5 — SN - does not accept SN correctly

*2021-11-27, version 2.0.5*

Can not set up app as I does not accept SN

### 1/5 — Unable to register

*2021-10-01, version 1.10.4*

Can’t set it up.

### 1/5 — Broken

*2023-05-24*

My Machine model not found in the system. Unable to register device!

### 1/5 — Crappy app

*2023-04-30*

Horrible app doesn’t work. Can not use with resvent devices.

### 1/5 — Apps are Terrible

*2023-04-28*

Neither app works. I registered, tried to log in, and it tells me to check my login info. I reset my password, still the same response. I try and re-register, email is already in use. Seriously a waste of time.

### 1/5 — Garbage!

*2023-02-19, version 2.0.5*

Garbage! Garbage! Garbage! Garbage! See All previous reviews. Can’t register (Not even on Chinese website). Won’t accept serial #. Garbage! Garbage! Garbage! Garbage!Apple, Why are you allowing this app?!?!?

### 1/5 — Just bad.

*2022-12-12, version 2.0.5*

Impossible to register, very hard to enter dates, and it’s bugged. Give it one date on the picker and it shows a different date. Doesn’t recognize the device serial number. This app is bad.  Can’t get support either because the link for it goes to a “page not found”. This app is hot garbage.

### 1/5 — Why

*2022-11-07, version 2.0.5*

Why encourage the download when the app won’t register. The date entry fields are also a day off. Horrible app

### 1/5 — Useless app

*2022-10-13, version 2.0.5*

Will not allow registration and use because it cannot recognize my unit’s valid serial number.

### 1/5 — Will not register device

*2022-10-11, version 2.0.5*

No support, app is not operable

### 1/5 — Broken Record

*2022-09-12, version 2.0.5*

You cannot register your machine useless app.

### 1/5 — Can not Register the device.

*2022-09-10, version 2.0.5*

I am not able to register the device using the devices SN number. So using the app on your phone is impossible. I was looking forward to seeing my stats on my phone.
