Must pay to use

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!

Response from developer

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

Rss is not possible

The rss feeds are not working

Response from developer

Hi. Due to high number of abuse, I no longer offer RSS feature for free. Please upgrade your account to use it. Thanks

Waste of time

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

Response from developer

Sorry for the issue. The bug has been fixed. Thanks

Does not work
