See how it works
Add a task, and your little virtual ocean fills up with junk 🗑️: plastic 🧴, paper 📄, and every now and then, a random stray sock 🧦...
Finish the task, your ocean clears right up. You'll even get a fun fact about how long that junk really sticks around out there. (Fair warning: it's way longer than you'd guess.)
Your next task could clean the ocean.
This is just the beginning. There's a bigger mission behind Krll: turning your daily wins over your plans and to-dos into real, positive change for the ocean — just like you clear the junk from your virtual one. Go build. Go learn. Go feel good with us.
