On: "Which app should I build with my designer friend?"

Top pick

Outfits app using AI

Building an AI outfit styling app offers the ideal balance of daily user retention, monetization via affiliate commerce, and rich UI/UX design challenges. While haircut previews have viral novelty, fashion apps provide ongoing utility rather than occasional usage. A flight tracker is heavily entrenched by well-funded competitors with costly data feeds.

Haircut previews with AI, which provides instant visual novelty and clear B2B2C distribution through local barbershops.

Wildcard

A collaborative virtual closet app where friends can style outfits for each other using AI try-on tools.

Best time

Start prototyping core UI flows immediately while testing lightweight diffusion models for outfit generation.
