## Most critical reviews (10 lowest-rated)

### 1/5 — No funciona la aplicacion

*2023-05-29, version 3.8.5*

Se queda solo el poner correo, no avanza mas la aplicación asi llegue los códigos o pin, Mala aplicación

### 1/5 — Stupid

*2022-10-04, version 3.8.5*

Can’t create an account without a code. Can’t get the code without creating an account.

### 1/5 — Not good

*2020-04-20, version 3.2.1*

Random glitches will work for a few days and then a new issue will spring up. Latest one is it stopped syncing with Fitbit then it won’t unpair Fitbit device to reset everything. I have lost days of sleep data that just randomly disappears from time to time.

### 1/5 — No registra

*2020-02-04, version 3.0.5*

Cuando pide el correo para el registro se queda ahí, no avanza más para configurarlo.

### 1/5 — Still no Garmin

*2020-01-29, version 3.0.5*

Still no ability to pair Garmin products despite press release saying so 2 months ago. Now version update notes say updated “garmin integration", but still no support to pair garmin products nor any visible front end garmin ability whatsoever.

### 1/5 — Misleading

*2019-11-13*

Can’t even access this without some other equipment. Useless to evaluate.

### 2/5 — Logs me out of app randomly

*2020-06-03, version 3.2.2*

When it works it’s great but from time to time it logs me out of the app and I can’t log back in. Instead of logging in with username and password it promps you to put in your email so it can send you a link. Well no link is ever sent making it impossible to sign in for days on end.

### 3/5 — Needs an Apple Watch app.

*2019-09-15, version 2.0.14*

As an Apple Watch owner I think this is a no brainer. I hate having to wear both when Apple Watch does everything needed for this to work.

### 4/5 — Made me notice my fatigue

*2021-02-13, version 3.4.2*

I have used this app for a while now and am impressed by it's simplicity. Its fatigue detection is quite accurate. Sometimes when I find myself feeling very tired around midday and look at app, it actually shows a dip in my fatigue score.

I use a Fitbit Versa 2 to track my data and I see this app also supports Garmin, which is great. But it would be great if we could use this app without requiring a tracking device. What if I wanted to switch to a different tracker like an Apple watch?

### 4/5 — Keeps improving

*2021-01-22, version 3.4.2*

Glad to see updates!  
Old review: The app is good. But the new view makes it harder to see the exact same stuff. I agree with having a trends button to see extra information (and further into the past, please) but I shouldn't have to go there to see things that used to be on the home screen.

### 4/5 — Improvement needed

*2017-03-15, version 1.3.5*

An in app alarm clock with Readiband vibrating to wake you up is needed to make this app better
