It's a little bit misleading to list "limited advertisements" as a green check-mark feature of the free plan.

Not only does it put a bad taste in my mouth (it looks like you're trying to obscure the fact that free has ads), a quick scan of the pricing page doesn't illuminate why I'd want to pay $8/mo for the next tier (which would remove the ads, I take it?).

It's also unclear if free supports using your own domain or not. The pricing page should probably make it a lot plainer that you pay to get a custom domain and no ads if that's indeed the case.

EDIT: The singlel.ink domain is a nice domain hack but the period breaks it in a weird place and I bet you're going to run into issues with it confusing people and them putting the dot in the wrong place.
