Founding Heroes · Polonia Challenge '26
Help us build Planet Heroes, together with Polonia
Planet Heroes is a global app from Poland that turns everyday activity into Green Coins. We're testing it in the US with Polonia members we trust — and asking for your support and your honest input.
Join between 11 November 2026 and 1 March 2027. Your 100 days start the day you sign up.
Nov 11 to Mar 1
Sign-up is open. Download the app and create your account any day in that window.
100 days
Counted from your own day 1 — so everyone's Challenge ends on a different date.
After day 100
Planet Heroes stays open. You keep your Green Coins and keep earning for your activity.
Why we're asking Polonia
We could test Planet Heroes anywhere. We chose to start with people who share our roots — and who will tell us the truth.
We're relying on Polonia to help us build a strong global app. So the Challenge opens and closes on two days that mean something to us.
In Poland, a hundred days has its own word: studniówka. This one is yours.
How the Challenge works
Watch 100 days fill up
Example: someone who joins on 11 November and opens the app every day. Scroll to move through their Challenge.
-
Day 1 · 11 Nov
You join. Your 100 days start.
+100 Green Coins for joining. Answer a short welcome survey, set your goal — for example a daily step count — and get +100 more.
-
Days 2–20
Every day you're active counts.
An active day is a day your steps or a bike ride sync to the app, or you log an action — a veggie meal, recycling, a greener trip or a clean-up. Miss one? Nothing resets.
-
End of each calendar month
A month closes. A bonus drops.
7–13 active days: 70. 14 or more: 150. Every day of the month: 350. You get the highest level you reached, added on the 5th of the next month (or the next business day).
-
Start · around day 50 · after day 100
Three short surveys.
+50 for each. Your answers go straight to our product team and decide what we change.
-
Day 100 · 18 Feb
Your first and last months are shorter.
Only days inside your 100-day window count, so a month you start or finish part-way pays at most 150.
-
After day 100
90 of 100 days? +1,000.
Be active on at least 90 of your 100 days and get 1,000 Green Coins. This example adds up to 2,350. Challenge bonuses top out at 2,470 — when day 1 falls on the 1st of a month — plus 200 for every friend you invite.

Be active — and let the app see it
Connect your steps, or log an activity: a bike ride, a veggie meal, recycling, a greener trip or a clean-up. Steps count on the day they sync, so open the app daily. You'll earn regular Green Coins for your activities too.

Green Coins
What Green Coins are for
You can exchange Green Coins for discounts and special promotions from our commercial partners in Poland. Partner offers in the US are not available yet — we'd rather tell you that now.
Check where and how each offer can be used before you exchange your Green Coins.

Two things we're asking for
How you can help
Join — and tell a friend
Our goal is at least 1,000 participants in the US. It's a goal, not a limit: everyone who joins by 1 March 2027 takes part on the same terms. Share your invitation link: for every friend who joins, you both get 200 Green Coins.
Tell us what works and what doesn't
We'd love to hear it straight. You'll get three short surveys — at the start, around day 50 and just after day 100. Your answers go to our product team and decide what we change.
Your privacy
Your data stays yours
- We read your step data only with your permission, and we never share it with brands.
- Organizations that share the Challenge never see any individual member's data.
- Connecting step data is optional. Activities you log in the app count as active days too.
For Polonia organizations
Share the Challenge with your members
Clubs, associations, parishes, schools and community groups can share the Challenge with their members using their own code. We prepare the text and graphics in Polish and English.
There is no competition between organizations and no rankings, and taking part is always voluntary for members.
Contact usQuestions
Who can join?
Anyone aged 18 or over who lives in the US and creates a new Planet Heroes account between 11 November 2026 and 1 March 2027. The Challenge is aimed at Polonia, but it's open to everyone who qualifies.
Do I need to buy anything?
No. No purchase is needed to take part or to earn Challenge bonuses.
What counts as an active day?
A day when the app records activity from you: your steps or a bike ride sync to the app, or you log an action such as a veggie meal, recycling, a greener trip or a clean-up. Simply opening the app doesn't count. Steps count on the day they sync — syncing a whole week at once counts as one day — so open the app daily.
What if I miss a day?
Nothing resets. Missed days only affect that month's bonus and the 90-day bonus.
Where can I use Green Coins?
With our commercial partners in Poland, for discounts and special promotions. Partner offers in the US are not available yet.
When does my Challenge end?
100 days after the day you sign up, counting your sign-up day as day 1. If you join on 11 November 2026, your last day is 18 February 2027; if you join on 1 March 2027, it's 8 June 2027. Check your own date.
What happens after my 100 days?
The Challenge bonuses stop, but the app keeps working. You keep your Green Coins and keep earning regular Green Coins for your activity.
What happens after 1 March 2027?
Sign-up for the Challenge closes. If you joined, your 100 days continue until they end. The app keeps working for everyone after that.
Is there a limit on participants?
No. 1,000 is our goal, not a cap.
Do I get anything for inviting friends?
Yes. You get rewarded for every friend who joins. Share your invitation link with a friend and you both get 200 Green Coins!
