How it works
Four beats,
then arithmetic.
You enter, you train, your wearable proves it, and the fund divides.
Nothing else moves the result. It turns on one thing: whether your wearable confirms you hit the target.
01 Enter
Pick an open challenge or write your own rules. Entries close when the window opens, so everybody in it starts together, and your entry joins one reward fund with theirs.
02 Just train
Nothing to press. Your wearable is connected once and sessions are detected automatically, server-side.
03 Get verified
The wearable’s data is checked against the target and the window. You’re a completer once it passes.
04 Results
Up to about an hour after the window closes: entry back in full, plus an even share of whatever is left over.
Those four beats as they look on the phone are on Inside Pledro, with every other screen in the app.
Where the money goes
Fifty people. Twenty pounds. Ten finish.
Step one
Fifty entries, one fund
Everybody who enters puts in the same £20.
Step two
£1,000, sitting still
It stays whole until the window closes.
Step three
Ten finish. The fund divides.
Ten get their £20 back. Pledro’s share stops at £100; the £700 above it is the reward.
Step four
£90 each, exactly the same
£700 divided ten ways is £70 apiece, on top of the £20 back.
The four steps, in full
- Everybody who enters puts in the same £20. Nothing is added from the side. The fund is exactly what the entrants brought.
- It stays whole until the window closes. Nothing moves early, and nothing is decided by anything other than whether people completed the target.
- The ten completers get their £20 entries straight back. Pledro is paid out of the £800 still in the fund, but never more than 10% of the fund, so here it is £100. The £700 above that is the reward.
- £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.
Pick an example. The sum runs again.
25 enter at £20. Ten complete.
The ten who completed are paid the same, to the penny.

50 enter at £20. Nobody completes.
Nothing comes back to the entrants, because completing is the only route to your entry. Real-money entries are not live yet, so no charity has been paid a penny.

Fee first, then the reward.
Pledro is paid first, never more than 10% of the fund, and everything above that ceiling is the reward.
When there is no reward at all
The order it comes out in: Pledro is paid first, out of the entries that stay in the fund and never more than 10% of the fund. Everything above that ceiling is the reward. So there is no reward at all until more than one in ten miss the target — everyone who completed simply takes their entry back in full and nothing more.
With 10 entrants at £10 and 1 missing the target, the £10 that stays in the fund is exactly the ceiling: all £10 of it is Pledro’s share, and the 9 who completed take their £10 back and nothing more.
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.
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.
Each person who completes is paid
Pledro’s share is the entries that stay in the fund, capped at 10% of it. Everything above that cap is shared between the people who completed.

On Grind challenges the same maths runs with no fee at all, the whole unreturned amount becomes the reward.
The referee
On your wrist, doing the arguing.
Apple Watch, Garmin, Whoop and more. Everything is checked against what the wearable saw. Nothing else counts.
What gets checked
Four gates between you and a completed challenge.
It came off a wearable
Typed-in activities are rejected. There is no manual path, so there is nothing to argue about.
The wearable was connected first
Only a device linked before you joined counts, and one wearable belongs to one account.
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.
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.
What you enter with
Grind now. Pounds later.

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.
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.
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.
£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.
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.
A review has a deadline
If a result is under review, everyone in the challenge is told why. We finish within 72 hours regardless.
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.
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 →
