### 1/5 — Not a one time fee!

*2026-06-13*

They charged me a $9.99 fee and it was supposed to be a one time fee. The app only lasted 2 weeks before it required me to sign in again and does not allow access unless I make another payment of $9.99 😤

### 1/5 — Really bad app

*2025-11-08*

I bought it and it’s not working at all!

### 1/5 — Doesn’t work

*2024-11-06*

Do not get it, doesn’t work at all

### 1/5 — Doesn’t work

*2024-10-09*

Tried to sign up but it doesn’t let me and gives me an error message so I can’t even use the app past the login screen. Can’t even reach out to the developer because there’s no info. Also the dimensions are tiny on an iPad

### 5/5 — It’s working March 2025

*2025-03-02*

Im an avid user of this app for years 
For a very small 10$ one time fee you have this platform with you forever 
Highly recommend! I have it!
