Expendr: Shopping Supercharged

expendr is a mindful spending system that inserts a pause between desire and checkout. Compare real prices across stores, add non-urgent items to a timed waitlist, and convert insights into budget actions that stick.

What you can do:
- Smart Shop: search across retailers, see real prices with cents, and spot lower cost equivalents fast. Impulse-risk items are clearly flagged.
- Waitlist: add items to a configurable timer with a quick three-tap unlock and subtle haptics. When you skip or pick a cheaper option, “money not spent” is recorded.
- Spending & Optimize: get a readable summary that states what you spent and how many purchases you made in the selected period. View category pie, spending over time, and a total saved card. Tap Optimize to apply specific, SMART tips in one tap: update a budget, tighten filters, set a nudge, or change a setting.

Why it works:
- Restores a short pause at the moment of choice.
- Surfaces better value without extra effort.
- Turns data into actions you can apply instantly.

Design:
- Dark mode by default with fluid animations and crisp, rounded cards.
- Sticky bottom navigation with a hold-to-switch page control for fast navigation between Waitlist, Smart Shop, and Spending.
- Clear labeling: cents shown on prices, retailer logos stamped, accessible contrast.

Trust and alignment:
- You stay in control; expendr introduces a pause and information, not hard blocks.
- Transparent math behind savings and classifications.
- Purchases open directly on the retailer site through our affiliate links, never through aggregator detours.

Who it’s for:
- Students and young professionals tightening discretionary spend.
- Budget-first households reducing impulse leaks on everyday shopping.
- Value maximizers who like comparison without the hassle.

The result: fewer regrets, lower effective prices through smart substitutions, stronger budget adherence, and a clear sense of control over what you buy.
