How it works
Four beats,
then arithmetic.
There is no clever bit hiding in here. You enter, you train, your watch proves it, and the fund divides. Everything below is the whole machine with the lid off.
Nothing else moves the result. It turns on one thing: whether your wearable confirms you hit the target.
Enter
Pick an open challenge or write your own rules. Your entry joins one reward fund with everybody else’s.
Just train
Nothing to press. Your wearable is connected once and sessions are detected automatically, server-side.
Get verified
The wearable’s data is checked against the target and the window. You’re a completer once it passes.
Results
Up to about an hour after the window closes: entry back, plus an even share of the reward fund.
On the screen
What each beat looks like.
The arenas
Open challenges are sorted into eight rooms, the ones we run ourselves, the biggest funds, the ones closing tonight, the free-entry way in. Each tile shows what’s actually live right now.
Everything before you commit
Reward fund, time left, how many are in, the entry, and the sentence that matters: an even split between everyone who completes it. Nothing is revealed after you’ve paid.
Setting your own rules
Create a challenge in four steps: the type, the rules, the window, the entry. Extra requirements, a pace to hold, a minimum heart rate, elevation, are each wearable-validated, so you can only ask for what a wearable can prove.
The result, on your profile and in the feed
A finished challenge writes a receipt: what you did, where you finished, what the reward was. It carries a challenge ID, and it’s the same record your circle sees in the feed.
Real captures from the current build
Where the money goes
Fifty people. Twenty pounds. Ten finish.
Step one
Fifty entries, one fund
Everybody who enters puts in the same £20. Nothing is added from the side. The fund is exactly what the entrants brought.
Step two
£1,000, sitting still
It stays whole until the window closes. Nothing moves early, and nothing is decided by anything other than whether people completed the target.
Step three
Ten finish. The fund divides.
The ten completers get their £20 entries straight back. The £800 still in the fund becomes the reward, less Pledro’s share. That share is half of the £800 or 10% of the fund, whichever is smaller. Here, £100.
Step four
£90 each, exactly the same
£700 divided ten ways is £70 apiece, on top of the £20 back. Fastest and slowest completer are paid the identical amount, and if the division wouldn’t come out exact, we take pennies less so it does.
The formula, three ways
Same rule, different rooms.
25 enter · £20 · 10 complete
50 enter · £20 · 10 complete
18 enter · £20 · 12 complete
50 enter · £20 · nobody completes
And if not one person finishes
Nothing comes back to the entrants, because completing is the only route to your entry. So Pledro keeps 10%, the same cap as everywhere else, and the other 90% goes to charity.
More people missing the target doesn’t make Pledro richer without limit. Our share is never more than 10% of the total entry fees, in any circumstance, and it is zero when everybody completes. Real-money entries are not live yet, so no charity has been paid a penny. Every case, on one page →
Run your own numbers
Move the sliders. Nothing is hidden.
This is the same formula the app uses to distribute rewards, not an approximation of it.
Pledro’s share comes only from entries that stay in the fund, and it is capped.

Each person who completes is paid
On Grind challenges the same maths runs with no fee at all, the whole unreturned amount becomes the reward.

Nobody’s watching. That’s the point.
Around the entry
Rules that only ever
work in your favour.
Each of these is enforced on our servers, not asked of the app, so it holds however you got there.
A way out
Free to leave while you’re alone in it
While you are the only person in a challenge, leave whenever you like, before or after it starts, and your entry comes back in full. No reason asked for. The moment somebody else enters, everyone in it is committed, including you: leaving then means your entry stays in the reward fund.
A minimum field
Three, or it doesn’t run
A real-money challenge needs three or more entrants. Come up short and it is called off, every entry is returned in full and everybody is told. Nobody has trained yet, because it can only happen before the start.
A ceiling on the entry
£250 public, £100 private
The most you can put into one real-money challenge. On top of that a weekly cap applies by default, you can set your own lower, and lowering one takes effect immediately. Looking after you →
The setter is in it too
Whoever set it is in it
The person who wrote the target enters on the same terms, at the same entry, as everyone else. Pledro never enters its own official challenges.
Held, not lost
A review has a deadline
If a result is under review, everyone in the challenge is told why. We finish within 72 hours regardless, and if the check later clears you, we pay your entry and the share you should have had out of our own pocket. Nobody already paid loses a penny.
Before you pay
Who set it, and are they in
The challenge screen tells you who wrote the target and whether they have entered it themselves, before you commit anything.
And the one that covers the rest: Pledro never takes more than 10% of the total entry fees, in any circumstance. The arithmetic, in full →
The referee
On your wrist, doing the arguing.
Apple Watch at launch, more wearables on the way. Everything is checked against what it saw. Nothing else counts.
What gets checked
Four gates between you
and a completed challenge.
Gate one
It came off a wearable
Typed-in activities are rejected. There is no manual path, so there is nothing to argue about.
Gate two
The wearable was connected first
Only a device linked before you joined counts, and one wearable belongs to one account.
Gate three
It happened in the window
It has to fall inside the challenge window, and you have to have entered before the workout began. Nothing you trained beforehand can count.
Gate four
The numbers are plausible
Flat heart rate, impossible pace, contradictory signals, flagged and held for a person to review, never auto-rewarded.
Held is not the same as refused. It means a human is looking, and every finished challenge leaves a receipt with a challenge ID so there’s always something to point at.
21:34 → 20:58
A PB is just proof you were wrong about your limit.
