### 1/5 — Must pay to use

*2025-03-02*

I logged in and attempted to send the first article. Immediately, I got an error that my “free trial had ended” and I needed to upgrade to send a PDF to Kindle. Not much of a free trial!

**Developer response:** Sorry there was a bug in the iOS authentication module. Can you share your email address so I could update your account? My email daniel@ktool.io

Thanks

### 1/5 — Waste of time

*2024-05-18*

Simple login also doesn’t work. If i request password change it just keeps saying passwords don’t match in a loop

**Developer response:** Sorry for the issue. The bug has been fixed. Thanks

### 1/5 — Does not work

*2024-04-06, version 1.8.3*

I did all I was supposed to but my file is not in my PDF

### 1/5 — Doesn’t work

*2024-01-27, version 1.8.3*

Doesn’t do what it’s supposed to do.

### 1/5 — Não consigo enviar nenhum artigo

*2023-12-27*

Na hora que eu tento envia da erro, pede pra eu contatar o suporte, mas não tem nada onde possa falar.

**Developer response:** Hi Raul. I’ve removed the flag on your account immediately and sent you an email to inform about it.

Unless you’re using multiple free account to abuse my service, you should be able to use the app without a problem.

### 5/5 — приложение работает!

*2025-10-30*

приложение работает в 2025 году с книгами Киндл. чтобы отправить книгу на читалку добавьте на сайте амазон почту этого приложения (его вы найдете при попытке отправить книгу когда придет письмо с блокировкой отправки). после аппрува книжки быстро долетают в читалку. супер удобно! и любого размера без всяких подписок и доплат) пользуйтесь!

### 5/5 — Incrível

*2023-11-09*

Melhor maneira de enviar artigos, documentos, newsletters para ler no Kindle. Ainda tem opção de converter os texto para o estilo ADHD. Vale cada centavo para ler textos em uma tela com menos luz.

**Developer response:** Thank you 😊
