Short answer. Room Planner, now called Home Planner AI (by Room Planner Ltd), is a long-established design app with a very large branded catalogue and polished pictures. Its own pricing page puts exact wall sizes, room scanning and floor plan recognition under its paid plans. Flatwalk is the newcomer, built for the phone, and it goes further into your real flat: your own floor plan, lights, the sun for your address, your street and city outside the windows. If you are planning one flat, you can do the whole job in Flatwalk for free. Pick Home Planner AI if you use an iPhone or want the widest choice of branded furniture.
