Jobs to be done

When my wallpaper looks wrong when I unfold my phone, I want to get a matched pair for both screens in seconds, so I can enjoy my new phone and show it off.

Ana, 31, designer in Lisbon (illustrative) · Bought an iPhone Duo on launch day; cares about aesthetics. Buying signal: Would pay a few dollars for a pack that fits both screens.

Build and go-to-market

Tech stack

Next.js on Vercel; image generation API (e.g. Flux via a hosted provider); Vercel Blob; Stripe

GTM channels

Shareable before/after screenshots; Pinterest SEO for "iPhone Duo wallpaper"; faceless TikTok slideshows of pairs

Risks

Main risk

Small, short-lived demand and free wallpaper incumbents adding foldable sizes.

All risks

Value: Attention — Rising but small X demand | Usability: High — DuoWallpaper and big apps | Feasibility: Attention — Image-generation cost | Business Viability: Attention — IP in generated images

Next validation step

Not recommended. If tested: a free web generator page with 20 pairs; kill if under 5,000 downloads in 14 days.
