This is a well made app and does what it does very well. it keeps track of the time you spend on sites you whitelist in the extension page and forces you to acknowledge how much time you're spending on these sites. Recommended! I especially love how it blurs the site in the background instead of taking you to a new tab. Aesthetic and functional.
Just one small feature request for the dev: add an option to play a game before selecting a time to unlock a site for. It's too easy to just select a time limit and keep on browsing; i would like for example the user to write a sentence in order to unlock the ability to extend the time.
