Challenges, competition & coin prizes

A challenge in OneMoreDay is a time-boxed contest built on a single health metric. You pick what counts, who can join, and when the window opens and closes. Progress is read from the activity you log and the health data you chose to connect, so nobody has to update a spreadsheet or take anyone's word for it.

The five challenge modes

• Competition, everyone works the same metric and the highest total wins.
• Race, the first player to reach the target wins, regardless of who ends up highest.
• Consistency, the score rewards showing up repeatedly rather than one big day.
• Together, a shared effort where the group is working toward one combined outcome.
• Team, squad against squad. Each side's members are pooled into one team score.

What can be measured

Challenges are scored on verified metrics rather than self-reported claims:

• Steps
• Running distance
• Sleep hours
• Meditation minutes
• Missions completed
• Mission consistency

Those values come from what you log in OneMoreDay plus any health sources you connect, Apple Health and Apple Watch through HealthKit, WHOOP, Strava, Fitbit, Garmin, Health Connect, Zepp, COROS and Suunto. Connecting a source is always your choice; the core game works on logged activity alone.

Tracking friends during a competition

Every challenge has a live ranking. Accepted participants appear in a paginated leaderboard that updates as progress syncs, showing each player's avatar, current value, streak and the health source their progress last came from. You can see who is genuinely ahead, how far ahead, and whether their number is backed by a connected device or logged by hand.

Challenges can be invite only, where the organiser adds specific OneMoreDay users, or open, where anyone with the invite link or join code can enter. Invitations are accepted or declined explicitly, so a leaderboard only ever contains people who opted in.

How coin prizes work

Challenges can carry a coin prize pot. Here is the exact mechanic:

1. Entry. The organiser sets an entry amount. Every player who joins commits that many coins. A commitment reserves your coins, it does not spend them yet, and your visible balance stays where it is until the challenge settles.
2. The pot. The prize pool is simply the entry amount multiplied by the number of committed players. A 50-coin entry with six players makes a 300-coin pot.
3. Settlement. When the challenge window closes, the pot is settled in a single atomic transaction. Every participant is debited their entry, and the winners are credited their share.
4. Winners. In race mode the winner is whoever completed first. In every other mode it is the highest score. Ties are fully supported, tied winners split the pot evenly, and any leftover coin from an uneven split is handed out one at a time so no coin is ever lost to rounding.
5. Refunds. If nobody produced a verified result, or nobody joined, every commitment is refunded in full and the challenge closes without a payout.

You cannot enter a pot you cannot cover. If a challenge needs more coins than you have available, the app tells you the exact amount required and the amount you actually have, and the join is refused rather than putting you into a deficit.

Coins are an in-game currency earned through play. They are not money, they cannot be bought with cash to enter a pot, and a challenge pot is not a wager against the house, the entire pool comes from the players and returns to the players.
