Doin' vs YuMuuv.

YuMuuv is for HR teams. Doin' is for anyone with an audience. Same word — “challenge” — completely different tools.

Who each product is built for

YuMuuv targets corporate wellness managers at large organisations. It integrates with Fitbit, Garmin, Apple Watch, and Google Fit to pull step counts, sleep data, and activity metrics into team leaderboards. The buyer is the HR department or a wellness programme budget owner. Employees participate because the company enrolled them — not because a friend shared a link.

Doin' is for creators, brands, and anyone who wants to challenge a group of people they actually know. One person creates a challenge — running, cold showers, reading, anything — and shares a link. Anyone who opens it can join. No company account required, no admin onboarding, no wearable needed. Photo proof replaces sensor data.

Proof mechanism: sensors vs. photos

YuMuuv's core mechanic is wearable data sync. Step counts, active minutes, and heart rate data flow in automatically. It's passive measurement — you wear the device, it logs your activity.

Doin' requires one photo per day as evidence of participation. The photo is timestamped server-side — you cannot back-date it. If you miss a day, your streak breaks publicly. The photo creates authenticity that a step count cannot: you can see Alex actually ran, not just that their watch logged movement.

Distribution: closed org vs. open link

YuMuuv challenges are internal. Employees are added by an admin; participation is confined to the company. There is no public join link, no Instagram share, no WhatsApp forward. The audience ceiling is your headcount.

Doin' challenges spread through shared links. A creator sends one link to their followers. A brand posts a challenge QR code at an event. A friend group uses a WhatsApp thread. The same invite-link flow handles 2 people or 10,000. There is no admin enrolment step — tapping the link is the join flow.

Use cases that each platform owns

YuMuuv owns: company-wide step challenges, HR-driven wellness programmes, wearable-integrated fitness competitions with SSO login and executive dashboards. If your budget is a wellness stipend and your audience is company employees, YuMuuv is the right tool.

Doin' owns: branded challenge campaigns (a brand runs a 7-day challenge for its customers), creator-audience challenges (an influencer challenges followers), conference activations (a conference runs a challenge for attendees), and friend-group bets. If your audience is outside your org — followers, customers, fans, friends — YuMuuv cannot reach them.

Which one to choose

Choose YuMuuv if: you are an HR manager running a company wellness programme, your participants are employees, and you need wearable data integration, SSO, and enterprise billing.

Choose Doin' if: you want to challenge people outside your organisation — your customers, followers, event attendees, or friends. Doin' does not require a wearable, a company email, or an admin to set it up. It works from a link, in a browser, in 30 seconds.
