### 1/5 — Скам , списали деньги и все . Приложение просто не работает

*2025-10-05, version 2.9.3*

Просто списали деньги , пишет ошибку соединения с интернетом при любом действиии

### 1/5 — Kein Export als mp3 möglich

*2025-09-15, version 2.9.3*

Kein Export als mp3 möglich und damit für mich nutzlos!

### 1/5 — I feel deceived

*2025-06-24, version 2.9.3*

While the app has a clean interface and a promising concept, I was disappointed to learn that it only allows for 50 minutes of text-to-speech usage. This limitation was not disclosed at the time of purchase, which I consider misleading. After paying for a full annual subscription, I feel deceived.

Unless this issue is resolved in the near future—either by removing the cap or clearly justifying and communicating it—I would like to cancel my purchase and request a refund. Please provide a response regarding how this will be handled.

### 2/5 — Perfect

*2025-05-26, version 2.9.3*

Re-edit, what happened, was good for Music Generation, why you changed?????

### 1/5 — App changed

*2025-05-25, version 2.9.3*

They changed their APP business model from generating music to creating voice text only. I have songs I want to download off the app but can’t.

### 5/5 — text to speech app

*2025-04-07, version 2.7*

My favorite app now

### 1/5 — A true limited free trial 🙏

*2025-03-30, version 2.4*

A true free trial without committing payment details would help assess if this app is OK. Can’t even try it without clicking purchase 😞 
Might be a worthwhile app 🤔 but who knows❓

### 1/5 — H

*2025-03-06, version 2.2*

Its not free

### 1/5 — Update deleted files

*2025-02-26*

I’m working on a children’s book and copy pasted multiple versions along with my favorite voice Lily to find out today they updated the app, my saved library is totally deleted and only 1/3 of the voices remain. I will not be resubscribing

### 5/5 — Best speech generation app, ever ❤️

*2025-02-19, version 2.0*

This is the best speech generation app, reading has become much more interesting))
