I also think the pricing is unsustainable.

Even if you are making mobile apps all year round, what if tomorrow you don't want to use Fuse anymore? You'd need to keep on paying the subscription to fix bugs.

What if you are a freelancer who only makes mobile apps from time to time? Again you need to pay the whole enchilada to be able to fix little bugs from time to time.

A price per published app would make more sense IMO. Allow devs to use the complete experience for developing, make them pay when they need to compile and publish the app. If you are confident that your users will love your dev experience (which seems your stronger selling point) this would not feel like a trap.
