### 1/5 — Broken App

*2026-07-08, version 1.11*

App is broken and won’t let you login

### 1/5 — App doesn’t work

*2026-07-01, version 1.11*

The app doesn’t work horrible

### 1/5 — Dead App

*2026-04-08, version 1.11*

Others have mentioned this, but you can’t log in from the initial menu. Last dev update 3 years ago.

### 1/5 — Scam

*2026-04-01, version 1.11*

This is a scam. If you pay for premium content, you will not be able to access it. 

If you search on google, you will find multiple other people saying the same thing. They do not respond to email snd there is no phone number provided. Stay away, they will steal your money.

### 1/5 — Horrible Service

*2026-02-26, version 1.11*

Can’t even login into my paid account. What’s the point of having an app on the app store and it doesn’t work or allow you to login. Poor service, do better!!!!!!

### 1/5 — Disappointed. BROKEN APP

*2026-01-28, version 1.11*

App is useless. CANT EVEN LOGIN. Paid for the 6 month subscription on my computer which came with ios app access… well the app has serious bugs and won’t allow me to login. The sign-in button doesn’t work after I input my login info — stays frozen on the login page…
I knew it was gonna be bad when I saw the app has 2 stars and its last update was 3 years ago. Will probably need to contact credit card company to request chargeback because I’m paying for “app access” but the app doesn’t even work.

### 1/5 — App doesn’t work

*2026-01-26, version 1.11*

The app doesn’t work

### 2/5 — Can’t login. Can only create account

*2026-01-06, version 1.11*

As others have mentioned, the login doesn’t work. It seems like creating your account from the app works and you can sign up for the paid service from there. Unfortunately I signed up and paid on browser so I can’t use the app. The dev team doesn’t seem to care about this issue since the last update says 3 years ago. This is part of the perks they list when signing up and can’t even use it. Very dissapointing since this is a paid service…

### 1/5 — Nonfunctional

*2025-12-16, version 1.11*

Paid for a subscription, then found the reviews. Same experience: app doesn't even allow login, so it's completely nonfunctional.

### 1/5 — APP DOES NOT WORK

*2025-10-10, version 1.11*

It is impossible to sign inn. This problem has existed for a long time and they don’t care to fix it.
