Saltydog MVP feature cut

This route is the discipline guardrail: preserve the two-tap order card, prove demand, and resist turning the first version into a travel super-app.

North star

Open fast. Show clearly. Get the right coffee.

Primary user: expat, nomad, or tourist in Vietnam with repeated coffee-order mismatch.

Primary context: phone in hand, standing at the counter, low patience, noisy environment.

Primary win: a barista understands the order without a back-and-forth translation ritual.

Ship now

The smallest product that proves the wedge and keeps the order-card action brutally fast.

  • Preset builder for drink type, sugar, milk, ice, temperature, strength, and takeout
  • Optional note field for edge-case modifiers like "if possible, a pinch of salt"
  • Full-screen bilingual barista card with huge contrast-first typography
  • Save up to 3 presets in the freemium tier
  • Offline-ready PWA shell so the card still works with bad cafe signal
  • Quick-launch home screen flow optimized for two taps
Earn later

Only after people repeatedly use the card and ask for broader preference support.

  • Unlimited presets and country/language packs
  • Icon-assisted cards for lower language reliance
  • Audio playback of the localized order
  • Food preference cards: vegan, allergy, no pork, no fish sauce, spice level
  • Shared presets for expat groups and travel creators
Do not touch yet

Tempting surface area that bloats the wedge before proof of retention exists.

  • Cafe discovery, reviews, or marketplace mechanics in v1
  • User accounts before strong retention exists
  • Complex loyalty systems, maps, or social feed features
  • Anything that slows the core order-card action
Validation loop

What needs to happen before scope expands

  1. 5 to 10 in-the-wild cafe tests with the card open on an actual phone
  2. 20 to 50 reactions from Vietnam expat and nomad communities
  3. One smoke-test page collecting emails for early access
  4. One bilingual review pass to tighten the Vietnamese phrasing before broad promotion
