Primary: $14/mo subscription. 14-day free trial, no card required to start. At 10k paying users → $1.68M ARR with near-zero infra cost (single static page + browser-local state, no backend until needed). Upgrade tier at $24/mo unlocks family profiles (Aanya gets her own strip).
Secondary: affiliate equipment + supplement. Time-gated, never aggressive. The "you might want a 24kg now" card surfaces at week 6 only if session intensity has plateaued — meaning the recommendation is earned data, not a banner ad. Partners: Rogue (kettlebells, ~8% affiliate), Momentous (protein, ~15%), Manduka (mats, 10%). Conservative blended take: $4–7/user/year on top of subscription. The trust is the moat — recommend rarely, recommend right.
Tertiary: corporate wellness. Companies pay $9/seat/mo for the same product, branded. The single-file architecture makes white-labeling a half-day job.
The Weekly Strip share. Every Sunday, the app generates a shareable image of the user's 7-day strip — filled circles, intensity bars, total minutes. One-tap share to iMessage / WhatsApp. Friends see it before they hear about the app. The strip is the ad.
12-Week Before/After Overlay. Optional photo capture at day 1; at day 84 the app produces a side-by-side overlay (with the strip underneath as proof-of-work). The honesty of "I did 84 sessions" is more credible than any transformation post.
Founder mode. Harnoor's exact case is the marketing: a 36-year-old with a young family who can't get to a gym. The landing page leads with his Wednesday-after-the-9pm-call moment, not a six-pack.
Injury. Every exercise screen has a permanent Skip / Scale button — never buried. Voice coach announces "skip if anything pinches" at the start of every session. The app refuses to be a coach for the wrong day; the recovery branch is the safety valve. Add a one-time intake (any current injuries? what hurts?) before session 1 — workouts route around flagged joints.
Over-reliance on voice. Some users will silence audio. Visual countdown + haptic pulse mirrors every voice cue, so the app works mute.
Plateau / boredom. After day 30, introduce theme weeks (Power Week, Mobility Week) so the format stays fresh without breaking the one-decision spine.
