Many people find themselves wasting time on the internet and utilizing it in unproductive ways. Studies have shown that when you limit the time you spend on social networking and other websites, you'll end up getting more done.
Once allows you to limit the time spent on distracting websites, encouraging focus, and mindfulness. Once lets you visit these websites once an hour. The timer starts when you close the tab of one of these websites and only applies it to the homepages. It works with websites such as Facebook, Instagram, X (Twitter), Reddit, and many others.
Love your work, not your distractions. Become more productive and stop wasting time on distracting websites with Once.

Once gets the balance right. Instead of blocking distracting sites so aggressively that you just disable the blocker, it gives you one check-in per hour. That sounds small, but it changes the behavior pattern completely: you can still glance at X, Reddit, or Instagram without disappearing into a 45-minute spiral. The setup is simple, the concept is easy to understand, and the approach feels humane rather than punitive. For anyone who wants more focus without going full digital monastery, this is a great little extension.
So glad I found this application. It is very useful, because I am oftentimes, very quickly distracted by the internet.
great tool
I love this so much, super simple and the blocking frequency of social media visit rather than aggregate time is genius and works great for me!
