Turn one-time snackers into weekly regulars.

Office snack decisions happen in 30-second breaks. This prototype rebuilds the Cafe tab around Snacc, trust labels, and one-tap reorder — the three levers we heard repeatedly in user interviews.

UX heuristics we follow

Nielsen's 10 + a few UX laws — mapped to concrete screens.

1. 1
   Visibility of system status

   ETA badge, cart badge, live order tracker, snack-window banner.
2. 2
   Match with the real world

   Language mirrors the office break — “4 PM snack”, “Team Tea”, “Filling under ₹149”.
3. 3
   User control & freedom

   Back arrows on every screen; qty steppers with − / +; “Undo” on cart removals.
4. 4
   Consistency & standards

   Same LabelChip, ItemCard, and Section components across screens.
5. 5
   Error prevention

   Free-delivery progress bar prevents surprise fees; portion/temperature labels prevent bad picks.
6. 6
   Recognition over recall

   Your usuals, Repeat your break, Most reordered near your office — all pre-surfaced.
7. 7
   Flexibility & efficiency

   One-tap reorder for regulars; browse-and-decide for new users.
8. 8
   Aesthetic & minimalist design

   Only 3 bottom-nav tabs; each card shows max 2 trust chips.
9. 9
   Help users recognise & recover from errors

   Empty cart has a clear next step (“Browse snack mode”).
10. 10
    Help & documentation

    “What our labels mean” legend on home explains every trust chip.
11. 11
    Hick's Law

    Menu split into 5 snack windows + 6 office chips — smaller decision sets, faster picks.
12. 12
    Fitts's Law

    Sticky bottom CTAs (Add to cart / Place order) are large and thumb-reachable.
13. 13
    Jakob's Law

    Delivery-app patterns users already know: sticky ETA, ADD button, cart bar.
14. 14
    Peak–end rule

    Delivery moment ends with celebratory success + 6-chip feedback — not a long form.
15. 15
    Zeigarnik effect

    Progress bar to free delivery + tracking checkpoints keep the task open in mind.
