A simple concept for a calorie tracking app failed to get traction, but the exact same idea went viral 24 hours later after adding polished animations. This shows that subtle interactions are a key differentiator when basic app creation has become commoditized and can be the difference between failure and success.

Instead of accepting default AI designs, proactively source superior design elements. Use pre-vetted Google Font combinations for typography and find specific MidJourney 'style reference' codes on social platforms like X to generate unique, high-quality images that match your desired aesthetic.

When using "vibe-coding" tools, feed changes one at a time, such as typography, then a header image, then a specific feature. A single, long list of desired changes can confuse the AI and lead to poor results. This step-by-step process of iteration and refinement yields a better final product.

Early versions of Figma failed to gain traction because designers, its target users, fundamentally didn't trust the tool's own subpar visual design. This meta-problem highlights that for a tool to be credible to its expert users, its own execution must embody the principles it espouses. A redesign was the key to unlocking user trust and adoption.

Not all parts of an application require the same level of design polish. Founders must develop an "editorial eye" to invest heavily in the core user experience (a 9/10) while accepting "good enough" for less critical areas like settings pages (a 5/10).

For highly commoditized interactions like text editor undo or canvas pinch-to-zoom, users have powerful, ingrained expectations. Failing to match these conventions doesn't make a tool feel "different"; it makes it feel fundamentally unusable and broken, regardless of its other features. Innovation should be focused elsewhere.

To create web apps that feel native on mobile, the most crucial design principle is aggressive reductionism. Vercel founder Guillermo Rauch's advice is to "delete, delete, delete, delete" every non-essential UI element to force clarity and respect the user's fleeting attention span.

The founders avoid creating a rigid, atomized design system because the product is still iterating too quickly. They accept a "messy" component library and technical debt as a trade-off for speed. Formalizing a design system only makes sense once the product's UI has stabilized.

AI coding tools generate functional but often generic designs. The key to creating a beautiful, personalized application is for the human to act as a creative director. This involves rejecting default outputs, finding specific aesthetic inspirations, and guiding the AI to implement a curated human vision.
