### 1/5 — Don‘t get it

*2026-05-29*

It worked…..
For the first two weeks the it stopped working and is now stuck on the home page. Genuinely disappointed.

I just downloaded it, and it won't open at all? I've reinstalled twice, same thing. And I've restarted my phone, checked for phone updates.. Nothing works?

### 1/5 — Not teen/adult friendly

*2026-04-12*

It uses writing only for a very long time when you sign up. People want to play with apps and listen to sleep meditation stories, but this app makes you read lots of writing without many animations and forces you to do “training” rather than fun and helpful sleep activities. It’s really boring and wouldn’t appeal to teens.

**Developer response:** Hi there,
Thanks so much for reaching out and we’re sorry to hear that you find the app too text-heavy. The training is designed to build lasting improvements to users’ sleep habits that continue to help over time. If this isn’t what you’re looking for – we do have a meditation track in the ‘More’ section of the app!

### 1/5 — Won’t let me open!

*2025-12-02*

I tried using this app and it won’t let me open it, as soon as I click it immediately sends me out, I delete and re-download AND reset my phone.

### 1/5 — can’t even log in

*2025-05-03*

wont let me put in my phone number - I left out the area code, put it in, spaces, everything but it said it wasn’t valid.

### 1/5 — Time waste.

*2024-09-17*

It’s a Great way to irritate someone.

### 1/5 — Won’t work

*2024-02-03*

It’s asking me for me phone number but it won’t let me put in my last digit.

**Developer response:** Hi there, sorry to hear there has been a problem with registering for Sleep Ninja. When entering your phone number, please leave out the country code (61) and you will be able to put in your full number.

### 2/5 — App won’t open

*2025-03-15*

We got through session 1 and tracked two times before the app just started working - it wont even open. Tried downloading it on our iPad and it’s not opening on that either. My daughter was enjoying using the app together so this is disappointing.

### 3/5 — Help please

*2025-11-19*

Every morning it says I have to go to bed! So I can’t track my sleep or level up
