Well, your link has 17 of these, why not one more?

Plus, this one is for meditation only, and has feedback, I doubt any of those links would give specific advice on meditation like this site does.

For people interested in meditation, I believe this is actually a great app.

More than half of the 17 are free.

I could spend a little more time searching for a list of exclusively free habit forming tools (or prepare one) but that's not necessary to prove my point.

My point is that free alternatives exist.
