Plans & billing
Is Krll free? What does Delphis add?
Krll is free to use. Delphis is optional and arrives with the official launch — $2.99 a month or $24.99 a year (save 30%) — and adds no ads, no daily task limit, up to 20 projects, repeating tasks, your whole archive, custom colors, friends as editors and offline use.
How do I cancel, change plan or restore a purchase?
Subscriptions are billed by Apple. Change or cancel anytime in your Apple Account's subscription settings — in Krll, go to My Page › Your plan › Manage plan. On a new iPhone, tap Restore purchases to bring back a plan bought with the same Apple Account.
Is there a free trial?
There's no trial, because Krll itself is free. Use the free plan for as long as you like and upgrade to Delphis only if you want more, once it's available.
Can I get a refund?
Purchases go through Apple, so refunds do too: request one at reportaproblem.apple.com. We can't issue refunds ourselves.
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.
