Speaker

David Siegel, co-founder of Glide, joins Y Combinator host Aaron for a Design Review episode about mobile app design and feedback on five startup apps.

Principles for mobile design

Siegel describes Glide as a no-code tool for businesses and says design helps software stand apart. He recommends following platform conventions, considering the conditions in which people use an app, and making text legible with sufficient contrast.

Pearls and BlueDot

The review praises Pearls for real-time search that tolerates a misspelling, native navigation, and useful medical reference content, while noting that some cards and controls are hard to read or tap. BlueDot gets users to a nearby EV charging map quickly, but the review finds it difficult to identify available stations and unclear what action to take next. The hosts suggest clearer availability cues, a more prominent next step, and testing the charging flow with drivers.

Duffel’s shopping flow

Duffel’s bright, playful design may suit college students, but small product images and a long catalog make browsing harder. Its emoji shortcuts are unusual, and tapping a shortcut does not always show the item the user expects. The review also flags weak text contrast and diversions into games and membership offers before a first order is complete.

BoldVoice and Eden Care

BoldVoice’s onboarding is clear but asks several questions before lessons begin; in the lesson, small, low-contrast controls make key actions less obvious. Eden Care’s wrapped tab labels and multiple loading states suggest a web-like mobile experience, while its care-finding screens offer limited actions and dense text. Siegel recommends making the app’s primary task easier to complete and ensuring taps receive prompt feedback.

Takeaways

  • Follow platform conventions and design for the setting where people will use the app.
  • Make the next useful action clear, especially when a user has found what they came for.
  • Show clear feedback when someone taps a control or adds an item.
  • Let users complete a first purchase or core task before introducing secondary offers.
  • Watch real users attempt the full flow and note where they get stuck.
