I had been quoted eighteen thousand pounds for an MVP. I described the app to Rork after dinner and was using it on my own phone before bed. It is not finished software and I knew that going in, but it answered the question of whether the idea worked.
Pros
Testing on a real device immediately. React Native means a developer can pick it up later.
Cons
Junior ran out in about three weeks. Push notifications took several attempts.
Problems it solves
Validated a mobile idea for £25 instead of a five-figure quote.

“Batch your instructions or you will waste the plan”
Used weekly for 6–12 months
One prompt is one message whether you are changing a colour or adding a login system. I burned thirty messages on small tweaks in my first week before working that out. Now I write one long instruction covering five changes and it goes much further.
Pros
Genuinely builds working mobile apps. Simple pricing once you understand it.
Cons
The message model punishes exactly the iterative style these tools encourage. Nobody tells you this up front.

“Good for client demos, not for shipping”
Used monthly for 6–12 months
We use it to show clients a working prototype of the app they are describing, which sells the project far better than a slide deck. Everything that actually reaches the store still gets built properly. The app-store side is where it needs the most help.
Pros
A working demo in a day wins work. Clients understand a phone in their hand.
Cons
Store review requirements and native permissions need real knowledge. Not a shipping tool for us.
