For friends who lift
The group chat says 'tomorrow'. The Pact knows if tomorrow happened.
Two plans, one pact: you see each other's standing, never the numbers.
You don't need the same plan — one lifts, one runs. In a Pact you each commit to your own thing and see each other's status and weekly consistency. When someone's behind, a Nudge says it so you don't have to.
- Each to their own: You: gym three times a week. Jonas: morning runs. Two commitments, one pact.
- See the standing: You see Jonas's standing and his weeks, never his numbers.
- One nudge: Jonas is behind this week. One tap, and the nudge lands.
- A receipt in the evening: Jonas logged a run. His standing is his own; your nudge moved it.
Different goals. Same seriousness.
Each of you picks your own commitment. You see title, status, and weekly consistency — never each other's numbers. One tap sends a Nudge when they stall, a Nice when they show up.

The evidence behind this
We grade what we lean on, and we show the grade. A is settled science; B is real but modest or genuinely contested — we say so rather than quietly leaving it out.
Half an hour of brisk walking — or any movement at that intensity — five days a week is associated with a 31% lower risk of dying in any given year, pooled from 661,000 people. And the steepest gain is the first one: going from nothing to something.

The caveat
Cohort data with self-reported activity — but dose-response, mechanism, and consistency make this about as close to causal as observational evidence gets. Steps variant: the curve flattens around 6,000–10,000 steps/day (Paluch 2022) — the round 10,000 is marketing, not science.
Strength training isn't only for looks: 30–60 minutes a week is associated with 10–17% lower all-cause mortality — independent of whatever cardio you do.

The caveat
Smaller literature than aerobic exercise; whether higher volumes help or plateau is unsettled ("unclear" per the authors).
