The simplicity of creating an MVP, integrating into existing products/services was easy once I had basic knowledge for building apps in React Native or Flutter (which is what they used). It can be difficult if you are not familiar working within these frameworks as there's some quirks that will trip up non native devs at first but it does improve quickly when using them again after getting comfortable! If your looking purely towards prototyping out ideas this could work well however we're still considering other options too so cannot recommend 100% yet :) For us its been great being able create simple solutions very fast without needing high level expertise - solving problems where traditional methods would have taken months which has saved time overall.
