Grubhub — Restaurant takeout & grocery

Grubhub is a food delivery marketplace connecting hungry users with local restaurants. The iOS app lets users browse restaurants by cuisine, filter by price and rating, customize orders, and track delivery in real-time. Beyond restaurant delivery, Grubhub offers grocery and convenience store ordering. The platform handles the full transaction — ordering, payment, delivery logistics — taking commission while saving users the hassle of calling restaurants or picking up food themselves.

Grubhub's interface optimizes for the decisive moment: getting hungry users to order before they abandon. Restaurant cards show estimated delivery time, ratings, and promotional offers prominently — the three factors most likely to drive clicks. Menu browsing supports easy customization with clearly priced modifications. The delivery tracking map provides real-time reassurance, reducing "where's my food" anxiety that would otherwise generate support tickets. Photography is crucial — appetizing food images do the selling work that descriptions cannot.

• **Location-Aware Launch**: The app detects location and shows deliverable restaurants immediately. No address entry blocks the first interaction, reducing friction for new users who just want to browse.

• **Filter Chips**: Horizontal filter chips (Offers, Rating, Delivery Time) enable quick refinement without entering a separate filter modal. Users can iterate through criteria rapidly while seeing results update.

• **Order Customization Flow**: Menu items expand to show modifications (extra cheese, substitute ingredients) with clear price impacts. The structured format reduces errors compared to free-text special instructions.

• **Real-Time Delivery Tracking**: The map shows driver location updating live. Status stages (Confirmed, Preparing, On the Way, Delivered) set expectations and reduce "where's my food" anxiety.

• **Reorder Shortcuts**: Recent orders appear prominently for one-tap reordering. This acknowledges that users often want the same thing from the same place, and friction shouldn't block repeat behavior.
