It requires registration
The first thing it asks after installation is to provide an email, so that they can email you a confirmation code. Why can’t you try it and decide if you want to register? More spam in my inbox, no thank you.Developer Response
Hello, thank you for your review. This is not a usual registration process, we require the email only to confirm that the user is a real person, to be able to protect our server resources from being consistently attacked by bots. If you are not sure you want to use the app and don't want to provide the email, you can have a look at the screenshots in the app description and make an impression (that's what the screenshots are for, ins't it?). We work constantly to provide the best possible experience for our users and we appreciate any feedback and suggestions. Thank you and have a great day!
