I'm usually not too fond of subscriptions either, but I have to say that Muse has the most ingenious subscription model I've ever come across: If you're using it casually, the free version is plenty (Remember that you can always archive stuff by exporting it, and 100 cards will go a long way. Plus, you can stop paying and still have read-access and even limited editing for your existing boards).

If you use it heavily as a daily driver, then the $3.99 or $9.99 should be a drop in the bucket. It scales very naturally between casual use and the paid tiers. Personally, I could probably do with the $3.99, but I'm choosing to pay the $9.99 since I want to support their ongoing research. Their podcast shows the enormous amount of thought they're putting into this, and it shows! Together with Blink (an SSH app with similar focus on UX design) this is by far the most productive iPad app I have.

Is that how most app subscriptions work? People usually call it “freemium”.

I mean, yeah, "freemium" is somewhat common, but in this case I find it particularly graceful in that the freemium doesn't limit the features, just the complexity of your board
