A clickable mock of the Dev version: no accounts, no server, free first year from the App Store, peer-to-peer friends, and calorie estimates.
The paywall is a $0 App Store purchase — the intro offer gives 12 months free, then $2.99/yr. Switch the stage selector to see the lapsed-user wording.
On Today, toggle food groups, then type calories or tap Estimate to compute a rough value from food weights. Estimates are always labeled and disclaimed.
On Friends, tap Simulate: receive Alex's file — that's the peer-to-peer JSON a friend AirDrops you. Alex then appears in Rankings with real stats.
Demo only — condensed to 5 tabs (the app has 7). All figures shown are estimates; the app is a tracking helper, not medical or nutrition advice.
