What actually separates them

Forest asks you to care about a tree; Opal removes the option. Both work, on different people, and the honest test is what happens after the first failure. If killing a tree makes you sit back down, Forest is cheaper, simpler and more pleasant. If killing a tree teaches you that nothing actually happens, the mechanic is finished and no amount of trying harder restores it — at which point enforcement is what is left.

Pick Forest if…

a gentle mechanic still works on you, and you want the simplest possible tool.

Pick Opal if…

you have already discovered that gentle mechanics stop working on you, and you want data about where the time went.

We build a competing product, so weigh this accordingly — the fuller picture on each is in Forest alternatives and Opal alternatives. Prices are bands as of August 2026, not quotes.
